yellowish white at the base of the segments. Sometimes the 

 bands are obsolete and sometimes, on the more anterior seg^- 

 ments, divided in the center by the brown. Beneath the color is 

 ashen gray in the females, but darker in the males. 



Habits of the Adult. 



Practically nothing- is known of the habits of the adult ; but 

 •it is reasonably certain that the species does not bite. It must be 

 fairly abundant at Lahaway in May, but Mr. Brakeley has never 

 taken it either in his room captures or in the field, day or night. 

 No specimens have been taken by any of the collectors in their 

 general gatherings, so the species must.be a very local one in 

 New Jersey. It certainly does not rank as a troublesome or 

 pestiferous one. 



In general appearance it resembles an undersized, dark pipicns 

 and would not be readily distinguishable from it did the two fly 

 together. 



Description of the Larva. 



The larva is illustrated on figure loi, with details of structure 

 greatly enlarged. When full grown it measures, exclusive of 

 anal siphon, 7-8J/2 mm. ,=.28-34 of an inch in length, is of a 

 delicate build and of a pale yellowish or bronzed grayish color. 

 The head is yellowish brown and the siphon dark brown, black 

 toward the tip, rendering it rather conspicuous in contrast with 

 the paler color of the larva. The head is large, almost the size 

 of the thorax, is not quite three-fourths as long as broad, rounded 

 in front and full at the sides, with a decided offset between the 

 vertex and the gen?e for the reception of the antennae. The 

 vertex is immaculate, with two smail hair tufts near the center 

 and one long hair slightly in advance of each; another tuft is at 

 the base of each antenna. The antennae (fig. loi, 5) are long 

 and slender, narrower beyond the tuft, curved inwardly, uni- 

 formly grayish brown, with the surface covered with long spines. 

 The tuft is large, composed of many long hairs and arises from 

 an offset at the outer fourth ; the apex with three ver}^ long- 

 bristle-like hairs, one short bristle and a very small terminal 

 joint, all articulated. The eyes are reniform, not large and are 

 situated on the sides where the head is widest; sometimes the 

 eye is divided into two parts, one large anterior body and a little 

 one at its center, posteriorly. The hairs composing the rotary 

 mouth brushes (fig. loi. 3) are long and silky, and are not
