 num, basal half of first antennal and legs except knees and tarsi, dull 

 yellow; under surface blackish, thickly clothed with rather long grayish 

 hairs. Head obtusely triangular, convex, slightly longer than width of 

 vertex; eyes small, rounded, not prominent. Antennae relatively stout, 

 pilose, joint 2 shortest, 1 and 3 subequal, 4 longest, 3 most slender. Pro- 

 notum with two transverse rows of rather coarse punctures. Abdomen

Putnam Co., Ind., Sept. 28; three adults and nymph taken 

 from the pools below a hillside spring (//'. 5". B.). White Plains, 

 N. Y., April — August {Bueno). Recorded heretofore only from 

 New York, New Jersey, Ohio and Michigan. Bueno (loc. cit.) 

 says : "It was taken in numbers at White Plains in a spring in 

 a marshy woodland, where it clings to the long mosses growing 

 into the water or walks about leisurely a short distance from 

 the rocky sides of the basin." Resembles americana but less 

 tapering behind, pronotum distinctly punctate, mesonotum not 

 visible and pale dorsal patches of abdomen usually better de- 

 fined and bluish instead of silvery-gray as there. 



1132 (1307). Microvelia Americana (Uhler), 1884, 274. 



Elongate-oval, robust for the genus. Winged form with head, pro- 

 notum, and under surface in great part black, thickly clothed with 

 minute appressed yellow or grayish hairs ; narrow edges of pronotum and 

 a transverse line on its front margin, basal joint of antennae, a large spot 

 on each connexival, legs except knees and tarsi, and last ventral in great 

 part, yellow; antennae, except base and knees and tarsi, fuscous-brown; 

 elytra fuscous-brown, the cells in fresh specimens vaguely paler. An- 

 tennae as in key, joint 2 shortest, 4 slightly longer than 3. Pronotum as 

 wide at middle as long, its humeral angles less prominent than in the 

 smaller species, apex of hind margin obtusely angled. Elytra narrower

Marion, Putnam and Lawrence counties, Ind., July 16 — Sept. 

 23 (W.S.B.). Palos Park, 111., and Golden, Colo., July— Sep- 

 tember (Gerhard). This is our largest and most widely dis- 

 tributed species, ranging from Ontario and New England west- 

 ward over almost the entire United States. No definite Florida 

 station is recorded, but both Van Duzee and Bueno include that 

 State in their distributional notes. Of its habits Uhler (1884, 

 275) says:
