Sparrow Lake is an expansion of the Severn river, situate a little south of lat. 45° and east of 80° longitude. Gelogically, this part of Ontario belongs to the Laurentian formation, and that of a very rugged type. The southwest side of the lake, where these coleoptera were taken, save in a few spots among the rocks, is wholly uncultivated and uncultivable to the Georgian Bay, a distance of from 20 to 30 miles. Till recently it sustained an immense forest growth, mostly pine, which has now disappeared, and has been succeeded by a dense and almost impenetrable jungle of briars and bushes of many deciduous species.

1. Amalopota Fitchi, n. sp.

Closely allied to A. Uhleri. Smaller; elytra smoky, about twice banded with white; nervures carmine, ocelli apparently wanting. Length, 6 mm.

Male: Vertex shorter and broader posteriorly than in Uhleri, hind margin very feebly emarginate, apex of the pronotum not advanced beyond the base of the lateral keels; frontal keel, viewed from the side, broader and more strongly rounded, with a more conspicuous notch at the base of the clypeus than in Uhleri.

“Godman and Salvin, Rhopal. I., p. 177, 1882, under teh specific name Lacinia, place Saundersii and Tellias, Bates: Quehtela and Ardema, Reakirt; Paupera, Felder; Mediatrix and Misera, R. Felder; Pretoria, Boisduval; Crocale, Edwards; Adjutrix, Scudder, and Adelina, Staudinger; all of which they consider but inconstant forms of one species.

In the same leaves of Populus angustifolia in which were found the tenthredinid (lepidopterous?) leaf-miners,* in the Canada Alamosa, northern Sierra county, N. Mex., in June, 1892, there were also found speciemns of a very distinct leaf-miner. It bears of striking resemblance to the leafminer of the vine found in the Mesilla valley of the Rio Grande. It possesses the sucker-like mouth of that miner. After being mounted in glycerine on a slide for several days, however, the outer portion of the distended sucker-like organ became transparent, exposing within what appear to be two stout rounded mandibles with teeth on their inner edges.

Mr. Butler (P.Z.S., 1892, p. 133) remarks concerning the Hyblœidœ (Hyblœinœ, I would rather write) as follows:-

“The position of this family is somewhat doubtful; the aspect of the species forcibly reminds one of the Tortrices, but the neutration does not altogether correspond with that of the Tortricidœ; at the same time the Hyblœidœ do not appear to be true Noctuites.”
