brown scales, the pale scales of the sides sometimes forming a 

 narrow border to this brow'n stripe ; the pleura brown, clothed 

 with patches of dirty white scales. The femora are yellowish 

 beneath and at the extreme apex on the upper side, the remainder 

 covered with mixed black and white scales ; the tibiae and the first 

 tarsal joints blackish brown, sprinkled with whitish scales, all 

 the other tarsal joints black. The fore and mid tarsi are nar- 

 rowly ringed with white at the base of the joints except the fifth 

 one in the anterior feet ; the posterior tarsi with broad basal bands 

 of pure white. The claws of the anterior tarsal joint in the male 

 (fig. 73, i) are very stout, unecjual in size and each with a large 

 median tooth; those of the mid tarsal joint (fig. Jt^, 2) are un- 

 equal, the larger long and slender with a long- blunt tooth one- 

 third its length from the base, the smaller with a median tooth 

 near the base. The posterior claws (fig. 73, 3) are equal, each, 

 with a median tooth nearer the base. In the female the claws are 

 equal and slender on all feet, with a single long tooth near the 

 base of each. 



The abdomen is blackish brown with pale yellowish bands at 

 the base of the segments and extremely narrow^ apical ones at the 

 base of the posterior three segments, irregularly merging into 

 the brown, becoming diffused at the sides until, beneath, the 

 scales are mixed together indiscriminately, the white ones pre- 

 dominating. The bands of the male are very wide, mixed with 

 brown scales and tend to cover the entire posterior segments. 



Habits of flic Adults. 



Nothing is known of the habits of this species in the adult 

 stage. The only specimens at hand were bred from larvae and, 

 though frequent collections were made at the places where the 

 larvje were found no specimens were ever taken. We know, of 

 course, that it is a woods mosquito and it probably never g-ets 

 away from their shade. We know also that it is an early species 

 and the probabilities are that there is only one brood. ]\Ir. 

 Coquillett believes that this species is like can fans; but there seems 

 to be no difficulty in discriminating between the two when the 

 thoracic vestiture is complete.
