THE STILT-BUGS. 



333 



tate, the carinae each ending behind in a small tubercle. Elytra with 

 membrane relatively short, finely, transversely rugose. Length, 8.2 — 

 9.5 mm. 



Lake and Porter counties, Ind., Aug. 1 — 28 (Gerhard). 

 Snicker's Gap, Va. (Davis). Algonquin, 111., May 20 (Hart). 

 Blowing Rock, N. Car., April 9 (Brimley). Canaan, Mass., July 

 12 (Frost). The general range of this species is northern, ex- 

 tending from Quebec and New England north of the 42nd Par- 

 allel, westward across the continent. South of the Ohio River 

 it is definitely recorded only from the mountains of North Car- 

 olina and Georgia. A specimen in the National Museum is 

 labelled "Duvall Co., Fla.," but McAfee expresses doubt as to 

 its coming from there. It is also known from Kansas, Ari- 

 zona and California. Uhler calls it "the subalpine analogue" 

 of Jalysus spinosus Say, and states that on Aug. 5 in eastern 

 Colorado he found them "flying in the bright sunlight and 

 they might easily have been taken for Tipulidce." About Buffalo, 

 N. Y., Van Duzee (1894, 172) says they "are common in weedy 

 fields and pastures. The summer brood appears about August 



1st, and is taken in winter hiber- 

 nating." The North Carolina speci- 

 men at hand has an oblong blackish 

 mark on disk of hind lobe of pro- 

 ^. // notum and the clavate tips of 



femora are brownish. The sulcus 

 of sterna also lacks the whitish 

 granules usually found along the 

 sides, but the structural characters 

 agree in all respects with typical 

 muticus. 



II. Jalysus Stal, 1862, 59. 



Very slender species having the 

 head sparsely punctate and (in our 

 eastern one) without spines; pro- 

 notum densely and coarsely punc- 

 tate, the front portion with two 

 smooth callosities, the hind lobe 

 strongly convex; scutellum with a 

 short, sharp inclined spine ; elytra in great part hyaline, reach- 

 ing base of sixth dorsal, clavus transversely rugose ; beak 

 reaching onto metasternum, its sulcus obsolete on head, narrow
