Stenaspilates flavisaria, new species.—♂. Expans, 33–38 mm. Head, thorax and abdomen yellowish-white. Ground colour of wings yellowish-white, in some specimens washed with a fawn-brown tint. Primaries with a dark-ochreous intradiscal line crossing one-third from the base, curved broadly outward from costa, then bisinuous to inner margin. Extradiscal line brown, bounded outwardly by a narrow white line, crossing at the outer third, with a gentle outward and inward curve to cubitus 2, then with a sharp outward semicircle, and another short curve to inner margin.

The following new species of mosquitoes have been found in New Jersey during the present summer (1905) in the course of the investigation conducted by Dr. John B. Smith.

Culex pallidohirta, sp. nov. ♀.— Head brown, occiput clothed with yellowish scales and a few dark brown ones intermixed; antenn♀ brown, the basal joint and basal half of following one dirty yellow; proboscis brown, with whitish scales scattered over the surfae save at the apical fourth; palpi brown, tipped with silvery white, four jointedm apical joint minute, flattened, spiny.

Culex siphonalis, sp. nov.—♀. Head brown, occiput covered with pale yellow scales, antennæ brown, basal joint and two following ones testacesou; proboscis pale brown, with dark brown scales scattered over the surface, covering the apical fourth; palpi dark brown, with minute terminal joint oval in form, pointed at the apex and slightly spiny. Mesonotum covered with pale yellow and brown scales at the sides and with a median vitta wholly of brown scales, the pale yellow scales sometimes forming a narrow border to this vitta; scutellum brown, with yellowish-brown bristles on the posterior margin; metanotum evenly brown; pleura brown, clothed with patches of dirty white scales; halteres yellowish-white, black at the apex.

In a recent number of this journal* Mr. Quayle gives some notes on the habits of the Californian Culex squamiger, Coq., and compares these briefly with those of a species occuring in Nw Jersey which we have been calling squamiger (following a determination by Mr. Coquillett), and suggests the possibility of there being two forms. The identification of our species with the Californian one has been doubted by Prof. Smith and myself since we learned of the salt-water habit of the latter; but not until Mr. Quayle pointed out the difference in the length of tracheal gills of the larva was a close comparison of the species made.

It will be noticed that in the preceding paper on Geometridæ, I have used the Comstockian terms of designating wing-veins. Heretofore these have not been used by any writers on this family of moths; in act, they have been very little used by writers in any family. The reason for this is, not that the system is not a good one, but because it is comparatively new. Most of the older writers have become used to the number system, having employed it in all their previous work, and therefore retain it to preserve uniformity, and perhaps make no effort to familarize themselves with the new dispensation.
