AMERICAN niPTERA. 29 



" Een 9 uit de omstreken van Quebec, in het Brusselsche museum 

 aanwezig, gelijkt zoo volkomen op dcze Europesche soort, dat ik het 

 gerust als zoodanig durf determineren " (v. d. Wulp, 1. c.)- I luive 

 before me a specimen from (Canada (J. B. ('aulfield) that agrees very well 

 with the description of Schincr's. 



53. L.a|>liria viiltur Osten Sacken, West. Dij)!. 286. 



Ten specimens from Washington Territory, Oregon and California I 

 identify with this, but, in all my specimens, the dorsum of the thorax 

 across the middle is clothed with short black pile. 



54. Lapliria antlira.v n. sp. 



9. — Black; head, tliorax, legs, and first two segments of the abdomen wholly 

 blaek pilose: remainder of the abdomen, except the extreme tip, densely clothed 

 with close-lying bright yellowish-red pile. Wings blackish. Length 21 mm. 



The pile of the face is abundant, on the lower part composed mostly of bristles. 

 Dorsum of thorax shining, wholly covered with short black pile, except the short 

 black bristles above the wing. The third— seventh segments of the abdomen are 

 wholly concealed beneath bright orange-red pile; the pile lies very closely and 

 thicklv. Tip of abdomen and venter black pilose. Legs wholly black pilose. 

 Wings' dark brownish or blackish; the anal and second basal cells in large part 

 hyaline; the middle of the fourth and fifth posterior cells lighter. 



One specimen, Northern California (0. T. Baron). 



This species must resemble L. rapax 0. S., and it is possible it may 

 be the other se.x, but the r'nfire lack of white pile renders such a view 

 improbable. 



55. Liaphria f'erox n. sp. 



9 .— Black : fecial gibbosity, thorax except the posterior part of the dorsum, tip 

 of abdomen and legs, black pilose ; face on the side above, beard, and posterior part 

 of dorsum with reddish yellow pile. Length 18-20 mm. 



First joint of antennae rather short, thick, the second distinctly more than half 

 as long, both clothed with black hairs. Facial gibbosity thickly covered with long 

 black bristles and finer black hairs, separated by a distinct interval from another 

 tuft of black hairs just below the antennae; on each side of the face above with 

 short, close-lying, bright yellow pile. Pile of the occiput below yellow, above 

 partly black. Dorsum of thorax nearly opaque brownish black ; on the inner side 

 of the humeri a large yellowish grayish poUinose spot; pile of dorsum erect, not 

 very abundant nor long, black, a little ligliter colored in front ; on the posterior part 

 and on the scutellum longer, yellow. Pleurae thickly grayish pollinose, pile sparse ; 

 the long, fan-like row in front of the halteres, black ; abdomen shining black, 

 rather thickly clothed with reddish pile, thicker on the posterior and mid- 

 dle parts of the segments, a large spot on the sides in front, more shining, 

 sometimes with short obscure pile. The outline of the pile on each segment is 

 more apparent when viewed directly from above ; when seen from behind more 

 changeable, and the ground color everywhere visible. Front and middle coxae 

 with yellow pile; legs wholly black pilose; the front tibiae and tarsi on the inner 

 side thickly yellow pubescent; hind tarsi somewhat reddish. Wings brownish on 

 the outer part, hyaline toward the base.
