536 PROCEEDINGS OF THE ACADEMY OF [1895. 



the enclosure large, well defined, and covered with about 12 strong, 

 somewhat wavy striae; tibiae and tarsi spinose; wings subhyaline, the 

 marginal cell excepted, nervures brownish, stigma yellowish, sub- 

 median cell of posterior wings terminating much beyond the origin 

 of the cubital vein ; abdomen shining, almost impunctate, first 

 segment not striated basally, pygidial area flat, rounded at apex, 

 distinctly margined laterally, strongly punctured. Black ; base of 

 clypeus, scape beneath, sometimes a small spot on inner orbits 

 beneath, pronotum, tubercles, a spot behind them, a stripe bordering 

 the dorsulum laterally, scutellum, spot on metanotum, large spot on 

 each side of middle segment, a fascia at apex of dorsal segments 1-5 

 and a narrow one at apex of ventrals 2 and 3 or 4, yellow; legs 

 except base testaceous, the fore and medial femora more or less 

 yellow beneath; basal half of flagellum beneath of the same color as 

 legs, which color sometimes extends to the upper portion. Length 

 8 mm. 



$ . — Colored like the 9 , but the clypeus entirely yellow and the 

 flagellum entirely black; eyes strongly converging beneath, the space 

 between them at the base of clypeus equal to somewhat more than 

 half of that at the vertex ; clypeus about twice as broad as long in 

 the middle ; flagellum long, somewhat setaceous, the joints more than 

 twice as long as broad, the first two joints about equal in length; 

 hind tarsi less thickened than in asperatus. Length 7-8 mm. 



Montana. The color of legs, large spots of middle segment and 

 almost want of yellow on orbits are good superficial characters to 

 separate decorvs from its allies.

Occurs from Canada to Georgia (Handlirseh), westward through 

 the more northern States to Washington. The spots on middle 

 segment are not constant. A 9 specimen from New Jersey, col- 

 lected in the latter part of June, I refer to simillimus doubtfully. 

 Its legs are highly colored with yellow and reddish, mandibles with 

 a yellow spot basally, and the furrow between the metapleurse and 

 middle segment is foveolate throughout, whereas in typical speci- 

 mens the fovea? are confined to the top. Another specimen, a $ , 

 from Washington State has the enclosure of middle segment striated 

 throughout.
