June, 1913] AlDRICH : NORTH AMERICAN SpECIES OF LiSPA. 134 



Abdomen rather depressed for a c?, black, abnost shining, with the follow- 

 ing parts light gray pruinose ; a broad anterior spot on each side of the second 

 and third segments, connecting with a broad central portion extending the 

 whole length of the segment; on the fourth segment the lateral spots are 

 even larger and sometimes brown pruinose, while the central spot is small 

 and indistinct, so that the middle is shining black in front ; fifth segment 

 velvety black, with a triangular pure white pruinose spot above, very con- 

 spicuous. Venter blackish gray, with long bristles on the first segment. 

 Bristles of the sides of the abdomen rather abundant, appressed on the second 

 and third segments, erect and dense on the first, fourth segment with about 

 three discal on each side and a row of marginal slightly interrupted in the 

 middle ; fifth with rather delicate but numerous bristles. 



Wings subhyaline, of normal form. 



Legs black with thin whitish pruinosity ; knees hardly at all lighter ; 

 middle femora a little slender toward the apex, tibise with a pair of 

 bristles on the outer side just below the middle; hind femora below with a 

 row of about 9 bristles, becoming long and slender past the middle, and a 

 single bristle on the hind and outer side below the middle of the tibia ; the 

 tibia has also rather long hairs on the outer side ; hind tarsi considerably 

 shorter than their tibiae (tibia 1.37 times the tarsus), the first joint almost 

 as long as the other four. Length 6 mm. 



Female. — Head about 2.50 times the front in width, but varying some- 

 what; face with a few scattering hairs on the sides; vibrissse generally well 

 developed. Abdomen more flattened, the median gray areas of the second 

 and third segments wider and more diffuse and with a slender longitudinal 

 line in the middle. Hind tarsus longer, almost equaling its tibia, the first 

 joint considerably shorter than the following four. Length 6.6 mm. 



In both sexes the front is not at all narrowed below. The abdom- 

 inal coloration as usual is sometimes not quite so well developed as de- 

 scribed above. 



Many specimens: Lawrence, Kans. ; Brookings, Elmira and Pierre, 

 S. D. ; Cache Junction, Utah ; Moscow and Elk River, Ida. ; Hood 

 River, Ore. Some of the specimens are cotypes of Stein's nigro- 

 macnlafa. 



Lispa salina new species. 



A large, hairy, gray species, with yellow palpi and a conspicuous white 

 spot on the tip of the abdomen in the male. 



Male. — Head 2.44 times front in width ; front brown, this color running 

 to a point near the antenna between two black patches which fade into brown 

 above ; around and behind the ocellar triangle are numerous small hairs ; the 

 upper two pairs of orbital bristles divergent, the remainder, about 6 pairs, 

 decussate; a row of proclinate hairs on the orbit outside the bristles; viewed
