146 ENTOMOLOGICAL NEWS. [May, '04 



From the H. H, Brehme bottle there emerged, on July 2d, 

 C. mtisiais, C. sylvestris and C. trivittatus. July 3d, musicus 

 and sylvestris hatched. The larvae were carefully examined 

 in alcohol, and three full-grown individuals were separated 

 out as probable trivittatus. 



A second collection made by Mr. E. Brehme, July ist, 

 yielded more adults and larvae. Collections made in the 

 Hatfield Swamp, August nth and 12th, also by Mr. Brehme, 

 yielded yet further specimens, always in company with C. 

 sylvestris. 



Outdoor captures of C. trivittatus adults were made July 2d, 

 at Trenton, by Mr. Grossbeck ; July 4th and 5th, at Chester, 

 by Mr. Dickerson ; July 13th at Summit, July 17th and i8th 

 at Deckertown, July 21st and 2 2d at Lake Hopatcong, all by 

 Mr. Grossbeck, and September 3d, in the Great Piece Meadow, 

 by Mr. E. Brehme. 



The larva (Plate ix, fig. i) is a stout, rather chunky wrig- 

 gler, grayish in color, 7 to 7^ mm. in length, and in general 

 build like sylvestris, with which it occurs. The head is com- 

 paratively small, one-third wider than long, evenly rounded in 

 front, brownish in color, darker at the base and blotched on 

 the vertex. The antenna (fig. 2) is less than half the length 

 of the head, sparsely set with rather large spines, tapering a 

 little toward the tip which is blunt, set with one long and one 

 short spine, a bristle and a stout little articulated peg. The 

 mandible (fig. 3) is set with small spines on the dorsal surface 

 of the base, and this is one of the few species so distinguished. 

 The mentum is triangular, the height at centre is equal to 

 two-thirds the base, the lateral margins are a little curved, 

 the teeth are small. The maxillary palpus is shown at figure 

 5 ; the mouth brushes are of the usual form, its hairs pectinated. 



Thorax somewhat angulated at the sides, marking the seg- 

 ments, and with a tuft of long hair at each angle. It is some- 

 what wider than long, with two transverse depressions on the 

 dorsal surface. 



Abdomen with the segments well marked, each with a lat- 

 eral tuft of long hair, decreasing in length posteriorly. The 

 comb on the eighth segment is arranged in an irregular patch
