A NEW GENUS OF BEES. 



BY J. C. CRAWFORD, JR., WEST POINT, NEBR. 



ProtciJidrenopsis, new genus. — Labial palpi four-jointed, r about 

 twice as long as 2-4 together, 2-4 slightly decreasing in length; maxillary 

 palpi 6-jointed, i and 2 subequal, longer than any of the following joints ; 

 3, 5 and 6 subequal, 4 slightly longer ; tongue long, lanceolate ; 

 mandibles simple ; labrum transverse, process of Jabrum large, almost 

 covering labrum ; foveas present, small ; stigma large, well developed, 

 nearly two-thirds the length of the obliquely truncate, subappendiculate 

 marginal cell, which is about as long as the two submarginals together ; 

 second submarginal fully one-third longer than the first, receiving the first 

 recurrent nervure about one-third from base and the second near apex ; 

 median cell along the median nervure, a little longer than the submedian, 

 the transverse median nervure joining the median just before the origin 

 of the basal nervure ; scopa on posterior tibiae, first joint of tarsi and on 

 venter. 



Type, the following species : 



Protandrenopsis fuscipennis, n. sp. 5 . — Black, somewhat shining, 

 almost entirely nude, the pubescence being confined to the golden- 

 yellowish anal fringe and scopa on legs, a little inconspicuous pubescence 

 around insertion of antennfe and on vertex, a line on prothorax passing 

 around behind tubercles, some yellowish pubescence on rear of head, on 

 under side of insect and a io-stf plumose hairs at extreme side of abdominal 

 segments ; all pubescence inconspicuous and not showing from above, 

 except fimbria and scopa ; head closely and rather coarsely punctured, 

 more coarsely so on sides of face ; process of labrum very large, concave, 

 the anterior margin bent upwards, process smooth and shining, basally a 

 little roughened and with a median ridge, apically subemarginate ; rest of 

 labrum covered with yellowish pubescence ; foveae narrow, short, deep, 

 the lower end nearer eye than the upper; mandibles black, obscurely 

 reddish medially ; mesothorax coarsely and rather sparsely punctate, the 

 pleura confluently so ; sides of metathorax finely roughened, the 

 truncation closely and finely punctate, becoming sparse and coarse at 

 top, laterally ; base of metathorax narrow, rounded behind and bounded 

 by a carina ; behind this an impunctate space ; enclosed base with 

 coarse, quite regular rugae, almost what is called a transverse row of 

 shallow pits in the genus Colletes ; wings very deeply infuscated ; 

 jiervures and stigma blackish ; tegula; black anteriorly, dark testaceous
