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,

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
