These two families immediately follow the Coccinellidæ in our lists, and are evidently related to them in many respects, the former, perhaps, the more closely, especially in tarsal strucutre. In habits there are, however, wide differences, the Coccinellidæ, as a already stated in a former paper, being chiefly aphidivorous, while the Endomychidæ and Erotylidæ are mostly fungivorous.

Egg.—Diameter, .035 inch by .02 inch high. Low conoidal, so much flattened as to be somewhat lens shaped, ribbed longitudinally with 37 striæ, 18 of which reach the micropyle, the striæ marked transversely with shallow cross striæ. Colour, dull olive. Duration of this period, 221 days.

♂—Head produced and very flat, rounded in front, wings reaching tip of abdomen; colour gray-brorvn. Length, 9 mm. Length of head, 2.3 mm.

Head thin foliaceous, margins very thiu, a median, thicker space, which beneath widens to base of head, forming a convex keel. Eyes touching prothorax.

During the past summer, while on a visit to the northern portion of this State, my attention was attracted to the presence of numerous mudcells on the lower surface of stones lying along the bands of the Wapsipinicon River, These cells, most of them empty, with one end forced off, somewhat resembled the single one with which some or our common mud-wasps start their establishment of the ceilings of little-used rooms, or on the rafters of outhouses, but very much smaller. The largest measure about 12 mm, in length and 8 mm, in breadth, while the small ones are only 5 mm. long and 2.5 mm wide.

In June, 1892, in company with Mr. Fletcher, who was anxious to obtain Erebia Discoidalis, Kirby, I made a visit to the famous Sudbury mining region. Leaving Ottawa on the 15th, at 3.40 p.m. we arrived at Copper Cliff at 5 a.m. the following day. As the hour was so early we tried a little collecting before calling on our friend, Mr. J. D. Evans, manager of the copper and nickel mines, who had kindly invited us to stay with him.

Trypeta (Acidia) tortile, n. sp., æ. Wholly yellow except a black dot above each wing; ovipositor brown; bristles black; scutellum bearing four bristles; thorax and abdomen shining; ovipositor flat, very borad, nearly as long as the last two abdominal segments. Wings hyaline, the anal cell, bases of marginal, sub-marginal, and of the final basal cell, also the apex of the second basal cell, yellow; a black spot on furcation of the second and thrid veins, and one on lower half of vein at apex of anal cell; a brown band commences on cossta between apices of auxiliary and of first vein, and extends to the discal cell, going over the small cross-vein and continuing as a yellowish streak into the discal cell; a second brown band commences on the costa between apices of the first and second veins, and crosses the wing, passing over the posterior crossvein, and near its terminus sending a spur into the third posterior cell; apex of wing from slightly before apex of the second vein to beyond tip of fourth vein, brown; first and third veins bristly. Length, 5 mm. Washington (O. B. Johnson). A single specimen.

The numbering of these notes is continued from p. 132.

(9.) Chionaspis ortholobis, Comst. In the middle of March Prof. Bruner sent me a Chionaspis, which he said was common on cottonwood in Nebraska, being also occasionally found on the white willow. It appeared to me to be a new species, and I was about to name it after its discoverer, but Mr. L.O. Howard, to whom I had sent specimens, delared it was ortholobis.

In the Canadian Entomologist, 1892, pp. 193–197, the writer published some notes on New Mexico Heteroptera an Homoptera. The notes on the fifty-three species in the present paper are additional and complete the list, so far as the names can be obtained, of all the Hemiptera collected by the writer in New Mexico and Arizona.

Raphia frater,var. coloradenis, Put.-Cr.

Mature larva.— Head rounded, partly retracted under joint 2, waxy greenish-white, ocelli black; mouth white. Body of nearly uniform width, joint 13 smaller; segmental incisures deep. Colour translucent, clear green, with many yellow piliferous dots, on joints 3 and 4 the dorsal ones tipped with red, and a central pair of these are prolonged into short, contiguous processes. On joints 5, 9 and 12 each, a transverse, curved, yellow band, reaching to the first dot above the spiracle.

Mr. Wolley Dod has recently sent me from Calgary quite a number of specimens of this form, and I consider it a valid species. The description, however, of Alberta (♂) is quite inadequate. There is great variation in expanse of wing, and in colour. Some examples are dark brown, some are yellow-white, like the pale N. Ridingsii; some are decidedly fulvous, like Varuna.

Most of the species recorded below were collected by the writer in the vicinity of Ithaca, N. Y. during the years 1888 and 1889. I have seen the collections of others and have found in them some forms that I had not collected. I have also examined the collection of Cornell University, and found several species not previously seen from the locality. This list is not complete, as undoubtedly more species will be found in the Cordulidæ and Gomphidæ.

(In 1889 and 1890, Mr. William Sheraton, of Wycliffe College, Toronto, collected some Odonata at Pictou, Nova Scotia, for me. At the end of the collecting season of 1889, he sent me a letter containing his field notes on the specimens captured. These observations are so interesting, in my opinion, that any publication in which they appear ought also to bear Mr.Sheraton's name as joint author. He has kindly acceded to my wish in this respect, although modestly protesting that his part has “been only such as any child could have done.” All notes in the present paper concerning localities, habits and dates are to be credited to Mr. Sheraton, while I am responsible for the determinations and the few bibliographical notes.)

Monostegia quercus-coccineŒ, n .sp.

Eggs apparently inserted by a series of thrusts of the ovipostior parallel to the midrib of the leaf. The saw cuts under the upper epidermis are confluent, forming a long blotch over 1 mm. wide and about 20 mm. log, running close to the midrib. The larvæ feed gregariously, eating the lower epidermis and parenchyma.

After reading Mr. J. W. Tutt's note on page 47 of Can. Ent., I have looked over many of our species of Pieris and Anthocharis with the following result:-Our genus Pieris is probably entirely pure and congeneric with the European. The majority of our species of Anthocharis are congeneric with Euchloë cardamines, as figured by Mr. Tutt, but some species are different and should be removed from the genus. I have not examined seven of the species given in Prof. Smith's list, but those which I have seen separate in synoptic form as follows:-Mr. Tutt's nomenclature of the veins differs from that in use here, as will be seen by a comparison of my figures (Figures 9 and 10) of Anthocharis sara with the figures on page 47 of Can. Ent.

The following list has for its foundation a collection belonging to the Experiment Station of the Kentucky State College. The diurnal Lepidoptera have not been made the object of special collecting by the Station entomologist, and doubtless a good many species will be added in the future:-

1.Papilio ajax, Linn. Common in all wooded regions throughout the State. High Bridge, Nortonville, Clay's Ferry, etc.

I did not suppose that anything I worte on North American Butterflies was likely to find favour in Mr. Edward's eyes, but in a long cirticism of my paper on Œneis, which I have just seen in Canadian Entomologist, there are two or three points on which he has so much misunderstood or misrepresented me that I cannot pass them by, as I shall do the greater part of his remarks, as unworthy of notice.

During the past few years Mr. Trevor Kincaid, of Olympia, Washington State, has kindly sent me many interesting arachinds from that region. Among them quite a number of phalangids, some of which have been described, others will be given in this paper.

In this group we have in some of the genera a return to the cephalic and thoracic ornamentation by horns or tubercles in the males, as shownin the Coprophaga I however, none of the Canadian species would be thus misplaced by anyone having even a slight acquaintance with the family, as aside from this character the resemblance is slight. From some of the Melolonthinæ they are not so readily distinguished, except by the position of the spiracles, as defined in a previous article.

Saitis Annæ, n. sp.—Length 3½mm.; width of abdomen, 1 mm. Cephalothorax, about as long as, but perhaps not quite so broad as abodemen. Abdomen broadly oval. Cephalothorax, about 1½times as long as broad; broadest between 2nd and 3rd rows of eyes. General colour grayish brown, not metallic.

In the two preceding papers of this series 36 species and 3 varieties of Acridiæ have been recorded as occurring in Indiana. Since the last paper, published in the Entomologist for February, 1892, appeared, five additional species have been taken within the State, and many lacts have been gathered concerning the life history, habits and range of the species previously recorded. Moreover, my private collection has been largely increased by exchange for specimens from other parts of the United States, and I have possessed myself of almost all the literature extant upon the group, so that I am enabled to clear up a few mistakes in synonymy rvhich crept into my first papers.
