On July 1, 1893, the writer collected a number of mealy bugs on clover (Trifolium pratense) at Ithaca, N. Y. They were found at about the level of the ground between the several stems of the plant, and also on the roots under the soil. On July 17 of this year the same insect was found on the same plant at Agricultural College, Mich. As they were both supposed to be D. trifolii, Forbes, a comparison was made with the original description.

Deltocephalus Callidus, n. sp.

Form and general appearance of signatiforns nearly, more robust, venation slightly variable, resembling that of compactus. Length 3 mm.; width 1 mm.

Vertex obtusely angulate, one-sixth wider at base than its middle length, scarcely equalling the pronotum; front long and narrow, but slightly wider than clypeus below; pronotum more than twice wider than long; elytra equalling the abdomen, rather broad, outer claval area slightly reticulated, central anteapical cell usually divided.

I have named my specimens in accordance with the material in the National Museum, arranged by Prof. Smith. The result is unsatisfactory, bacause this is the gum-tree larva described by Edwards and Elliott as I proepilata, Grt. (Papilio Ill., 135). The larva mentioned in Guenée as delineata has a different food plant. There is evidently some confusion here, which must be adjusted by the next monographer of the genus.

(7) Chionapsis furfurus, Fitch; 1856-1869. N.

A very common species in Massachusetts, recorded from Amherst, Worcester, Andover, Lawrence, and Methuen, on wild redcherry, pear, wild and cultivated apple, flowering quince, chokeberry, shad-bush, and black alder. It is known from Virginia, Maryland, Pennsylvania, Illinois, Indiana, West Virginia, North Carolina, Ohio, New York, Kentucky, Rhode Island, Connecticut, Georgia, Utah, Kansas, New Jersey, and Washington, D. C., on choke-cherry, wild red cherry, wild and cultivated apple, crab apple, pear, peach, Japan quince, cherry currant, red flowering currant, and European mountain ash.

Ripersia arizonensis, n. sp.

♀ enclosed in a broadly oval snow-white waxy sac, about .3 mm. long, 2 mm. wide, 1½ mm. high, sac widest between middle and caudal end.

♀ oval, about one-third longer than broad, shiny, light purplish-brown, about .3 mm. long. When boiled in K. H. O. turns reddish-brown. Derm colourless, with numerous bristles scattered over the dorsum. Antennæ 6-jointed: 6 longest, joint 4 shortest; formula 6, 1, 2, 3, 5, 4. Each joint with several hairs, joint 6 quite bristly.

Antonina Nortoni, Parrott and Ckll.

Sac white, subglobular, cottonlike, completely enveloping female.

♀ oval, plump, cream-coloured, with slight tinge of brown on margin. Boiled in caustic potash, becomes transparent, with the exception of the antennae, the two pairs of spiracles, and ultimate segment, including anal region, which are a dark yellowish-brown. There are many single glands, especially towards and about posterior segments; they are less numerous anteriorly. On outer side of each spiracle there is a crescentic group of rather large circular glands, placed very close together. Antennae aborted, short, thick, composed of three segments measuring respectively 18–25, 13–16 and 27-28 mm. Mouth-parts large Spiracles chitinous, large and extended. Anal orifice circular, situated in a depression, surrounded by a strong chitinous ring. Anal ring with six long, stout hairs measuring from 53 to 89 mm. in length.

Apparently related to Farmairia, Sign. ♀. Scale waxy, hard, brittle, cone-shaped with radial ridges and furrows. Antennæ five-jointed. Anal-plates curved; the two together forming a ring. Each plate is furnished with ten long hairs. Type, E. rugosa.

Edwallia rugosa, n. sp.

♀.—Scale white; wax hard and brittle, cone-shaped, having the appearance of a barnacle, and radially ridged or fluted like the shell of Pecten. The base is slightly oval in shape, being wider anteriorly than posteriorly; the anterior side is slightly convex, so that the top of the scale is caudad of the middle. A number of fine concentric rings run around the scale parallel to the base.

♀ scale 1.6 to 1.8 mm. in diameter, .5 to .6 mm. in altitude, circular, quite convex, roughish, a light brown with slight tinge of pink; ventral scale thick, white at centre with brown on margin, not easily separated from scale, when detached from host plant leaves but a very slight trace of white; exuviae sublateral, often nearly marginal, orange, covered with whitish secretion.

♀ oval, deep yellow, with dark brown on margin of posterior segment, and yellowish brown about mesal lobes and region of proboscis. When boiled in caustic potash becomes transparent, with mesal lobes a yellowish brown, and region of proboscis a reddish brown.

This subfamily is rather poorly represented in Arkansas, only eight of the thirty-one genera recognized by me as occurring in North America having been found within its borders, and only one genus, Orphula, is represented by more than a single species.

Mermiria rostrata, McNeill.—Has been found in the State, but its occurrence at Mackay, I. T., makes it altogether probable that it belongs to our fauna.

The pioneer work done by Prof. Comstock on the Coccidæ of America has put all workers in this group of insects under lasting obligation to him. It was inevitable, however, that, taking up a new subject and handling a vast amount of material for the first time, mistakes should have occured. An instance in point is the curious mixing up of the material which occured in the case of the description of the species known as Aspidiotus convexus, Comst.

Nidularia (?) californica, n. sp.

♀ covered with wax resting on a thin white secretion. Colour orange-ferruginous, shiny, varying greatly in size and shape. The average specimens are about 3 mm. long, 1½ wide, and 1 mm. high; generally pyriform, but it is difficult to give any special form, as the insect adapts itself to the position on the plant.

After boiling in K. H. O. derm is colourless, mouth parts, glands and caudal portion remaining brown. There are indications of antennae, which are very small and very bristly, segmentation not visible. There are four large disklike spiracles on the ventral surface, each disk contains numerous glands. There is a row of thick, blunt spines on each margin, and one on the dorsum. These marginal spines are shaped like a spearhead set in a socket. With these there are several rows of round spinnerets. Rostrum attached to a prominence, which, however, varies with the position the insect adopts.

Genitalia: female, ultimate ventral segment nearly four times wider than long, posterior margin slightly emarginate with a short broad medium tooth; male valve broad, short; plates broad at base, concavely, attenuately pointed, two and one-half times longer than valve, equalling the pygofers, which are thickly beset with stout hairs.

Described from two females and two males from Holly., Colo. The small size and the black spot near the anal angle of the elytra at once distinguish this species.

The following notes relate in large part to additions recently made to the Canadian fauna through the activity of collectors in the Dominion. several species which their possessors were unable to identify by means of the tables have been submitted to me, and, proving new to the Canadian lists, are incorporated in these pages, that students may have access to the descriptions. The families are taken up in the order of their treatment in the Canadian Entomologist.

Hadenella subjuncta, Smith. A few at light in 1897 about the beginning of July. (See page 323, Vol. XXX.)

Drybota stigmata, Grt. Cartwright.

Polia confragosa, Morr. Sept. 15th (1896). Three specimens at sugar in Elm Park.

Laphygma frigiperda, S. & A. Sept. 8th, one at bloom.

Eupsephopæectes procinctus, Grt. Cartwright. I think Mr. Heath has only taken one of these fine insects.

Trigonophora periculosa, Gn. Cartwright.

Brotolomia iris, Gn. June 19th, etc., several at light, also taken resting on walls of house.

At Wooster, Ohio, this species was observed in the fieds on May 26, and at Alliance, nearly due east, on October 24, while at Bridgeport, in the extreme eastern central part of the State, it was found, active, on November 4, all during 1898. It appears to have been more numerous of late in the vicinity of the south shore of Lake Erie than elsewhere in the northern portion of the State, and more abundant than I have formerly observed it in the same latitude in Indiana and Illinois.

By the kindness of Prof. L. Bruner I have recently been able to study specimens of the South American Orphula pagana Stal., the type of the genus, and so to compare its structure with that of our native species latterly referred to Orphula. By this it appears, as Mr. Bruner has pointed out to me in correspondence, and as Mr. A. P. Morse has suggested (Psyche, VII., 407), that our species should be referred rathar to Orphulella, separated by Giglio-Tos from Orphula in 1894, though this was afterwards regarded by him as having only a subgeneric value Orphula in the stricter sense of the term is not, so far as I know, represented in the United States. Orphulella is the most widely distributed genus of North American Trypalinae and the most abundant in species. Those known to Prof. J. McNeill in his recent revision of our Tryxalinae were well separated by a table which I have here made the basis of a new one to include a considerable number of new forms. Besides describing these, I have added notes of distribution of the others, based on the collections in my hands, and given their principal synonymy.
