We take great pleasure in presenting this month a likeness of Prof. Saunders, who must be well-known, if not presonally, certainly by reputation, to every reader of the Canadian Entomologist. He was one of the founders of the Entomological Society of Ontario in 1863, and became its President in 1875, which position he held continuously till he was appointed Director of the Experimental Farms of the Dominion in 1886. From 1874 to 1886 he was the General Editor of this Magazine, and conducted it with singular ability and success.

These conspicuous spherical galls occur somewhat rarely at Ottawa upon the stems of Solidago rugosa, and have been found to yield only the handsome fly with produces them, and its parasite Eurytoma gigantea, Walsh. The 24th May last I spent at Casselman, about thirty miles southward from Ottawa, with Mr.Fletcher, and we found the galls abundant upon Solidago serotina, upon the banks of the South Nation.

Platyura lurida, n. sp ♀. Head and antennæ black, first two joints of the latter and the mouth parts somewhat yellowish. Thorax, pleura, scutellum, abdomen and legs, pale yellow, the tarsi toward the apex brownish-yellow, the thorax marked with three reddish-yellow vittæ. Wings hyaline, slightly tinged with yellowish toward the costa, otherwise unmarked; tip of auxiliary vein nearly twice the length of the humeral cross-vein beyond the base of the third; sub-costal cross-vein nearly three times the length of the humeral beyond the latter; anterior branch of the third vein oblique, ending its own length beyond the tip of the first; sixth vein reaches the wing margin. Length, 6 mm. Washington. A single specicmen from Prof. O. B. Johnson.

The genus Kermes of modern authors contains about a dozen subglobular forms, found on oaks, with one exception. These insects might be taken for species of Lecanium, but a microscopial examination of their characters, especially in the larva, shows that they are quite distinct from that genus.

On July 9, 1892, I found in the Grand Canon, Arizona on the Hance trail, near the Colorado River, numbers of the green galls of this species on the narrow-leafed Salix sp. (probably S. longifolia.) Three that were picked on this date measure 19 to 20 mm. in length, and 11 mm. in width on widest portion near base. They preserve their light green colour, except for their whitish, thick pubescence. Some last year's galls were also found in the canon on the willows near the stone cabin. They measure 16 to 17 mm. in length, and 10 to 11 mm. in width. They are more spread out apically; therefore not conical in outline, and are reddish-brown in colour, probably from being weathered.

Eighth stage.—Head shining black, yellowish punctured around the mouth, antennæ yellowish; eye and jaws black; width, 1.8 mm. Body ochreous yellow, 6-annulate with irregular quadrate sub-dorsal (two per segment) and lateral (one per segment) black spots, confluent on joint 13; sub-ventral ridge faintly discolured; anal plate blackish. No white secretion. The larvæ do not feel in this stage, but seek for soft wood in which they bore their galleries for pupation.

XII. The Hydrophildæ of Ontario and Qubec (concluded).

This paper can scarcely be considered in any sense an original one since it consists almost entirely of tables published in greater detail by Dr. Horn in his reviews of this portion of the Hydrophilidæ. By removing the extra-limital forms, I have been able in some cases to modify the synopses so as to make them a little easier to follow, and it is hoped that they will prove of use to many students of the Canadian fauna who may not see the more complete originars. with this prelude, which will place the credit where it properly belongs, we may proceed.

2931. Ptenidium pullum, Makl.—Not rare. In grass tufts in winter.

2951. Trichopteryx xanthocera, Matth.—Rare. Under log in Feburary.

2952. Trichopteryx parallelopipeda, Matth.—Rare. In grass tufts in February.

2953. Trichopteryx diffinis, Matth.—Common in November in seed pods of fox glove.

The following list embraces all described species of the order Siphonaptera. For descriptions of all species known at the present time, see the preceding papers of this series, where will also be found a partial bibliography. For the complete bibliography and synonymy of all species published up to 1880, see Taschenberg's Die Flohe.

In 1875–61 I pointed out that the earliest name for the genus, which is commonly called “Acronycta” by authors, is Apatela, Hubn., 1806; the type and sole species cited in the Tentamen being the European A. aceris. My attempts to group the American species and brings them into correspondence with the European forms under subgeneric titles are unsatisfactory, as I have not been able to compare sufficiently the European species in all stages with our own.
