40 Journal New York Entomological Society. [Voi. v. impression deep ; elytra convex, smooth, with two fine punctures, sutural stria almost touching the base, marginal stria broadly interrupted. Length, 2 mm. Habitat : Pennsylvania, District of Columbia, Georgia, Illinois. Resembles T. xanthopiis but lacks the second sutural stria; it is also smaller and paler in color. T. gemellus Casey. — Slender, convex, dark rufous, base of an-tennae and legs testaceous ; thorax broader than long, sides rounded ; feebly sinuate before the hind angles, which are obtuse, median line fine ; elytra scarcely wider than the thorax, sutural stria fine, with traces of a second stria. Length, 2.4 mm. Habitat: New Jersey (Cape May). T. dolosus Lee. — Pale rufous, elongate, convex ; thorax rather flattened, quadrate, sides slightly rounded ; posterior transverse impres-sions deep, finely punctate ; base deep, more marked at the angle ; elytra broader than the thorax, elongate, smooth, distinctly bipunctate ; su-tural stria almost touching the base, marginal stria interrupted. Length, 2.25 mm. Habitat : Massachusetts, District of Columbia, Illinois, Missouri, Arizona, Texas. T. fuscicornis C/id. — Entirely reddish brown, with the last seven joints of the antennce fuscous. Thorax of the form of granarius, with the rounded sides directed obliquely towards the base; hind angles a little prominent and acute ; transverse basal impressions less deep, and has but one puncture at the middle. Elytra elongate, like those of dolosus, but the sides are more rounded and above are more convex. Length 2.5 mm. [To be Continued.^ SOME SYRPHIDiE FROM LONG ISLAND. By Nathan Banks. The flies in the list given below were taken within a few miles of Sea Cliff, L. I., N. Y. The island, or at least this portion, is not so rich as the adjacent mainland in this group of insects. Specimens are usually more rare here, and species common elsewhere are unknown, or at least uncommon, here. Such, for example, is the case with the two large species of Heiiophili/s, with Syrphus torvus, Mesograpta getninata, and others. Along the shore we find two characteristic species. Eristalis ceneus and Triodonta ciirvipes. Among the more interesting
