inch in length, the beak is about one-third the length of the body, 

 and the wings expand 12 mm., or about half an inch. The head 

 is dark brown, with scattered creamy yellow scales and a dis- 

 tinct creamy border to the eyes. The palpi in the female are 

 brown, four jointed, the apical one small, oval in shape, pointed 

 at the apex and distinctly spiny or hairy. In the male (fig. 41, 4) 

 the palpi are wholly brown, the basal joint twice as long as the 

 two apical ones taken tog'ether. The antenna of the male is 

 plumose, paler than the palpi, with shape and number of seg- 

 ments as usual. The female antenna is normal. 



The thorax is dark brown, covered with short, upright scales, 

 the yellow ones scattered over the surface, often collected into 

 stripes. Legs with the femora pale brown, darker at the apex, 

 and yellowish beneath ; the tibiae with mixed yellow and brown 

 scales, dark brown at the apex ; the tarsi dark brown, almost 

 black, broadly white banded at the base of the joints in the 

 posterior legs. In the mid-tarsi the bands are narrower and 

 almost lost in the anterior ones. 



In the male the claw joint of the anterior tarsi (fig. 71, 3) is 

 excavated inwardly, with one long claw and a shorter one, each 

 with a median tooth, nearer the base. The mid claw joint 

 (fig. 71, 4) is short, not excavated, with a very long and a short 

 claw, each with a single tooth near the base. The claws of the 

 posterior tarsi (fig. 71. 4) are small, of ecjual length and each 

 with a single claw. The claws of the female (fig. 71, 2) are 

 alike on all feet, somewhat longer than those on the male pos- 

 terior feet and with one tooth on each. 



The abdomen is blackish brown, broadly banded at the base of 

 the segments with creamy white, which sometimes encroaches a 

 trifle on the apex of the anterior segment. The bands become 

 broader toward the sides, more so posteriorly, until they connect 

 at the sides and the apical segments are often wholly white. The 

 bands are very broad in the male so that the abdomen appears 

 white, banded with black. The under side of both sexes is dirty 

 white. 



Habits of the Adult. 



Little is known of the habits of this species in the adult stage. 

 It is as early on the wing as canadensis, occurs in the same places 

 and bites just as hard. And having said this, I know in addition 

 only that after the middle of May nothing more is seen of the in- 

 sect. Its life seems much shorter than that of canadensis and it 

 seems not to range far from the place of its birth. Of its biting
