234 ENTOMOLOGICAL NEWS. [Sept., '04 



while busy stridulating, I could usually take him before he 

 could get in position to spring. So keen and shy are they, 

 however, that often, after a careful advance, occupying sev- 

 eral minutes, the singer would notice me when still several 

 feet distant, and would not again make a sound, no matter 

 how long I remained motionless. 



' Their mode of stridulating closely resembles that of Chor- 

 thippus curtipennis ; the sound produced is, however, far 

 stronger. 



' The males are brilliantly colored, the black lateral lobes 

 of the pronotum and the coloration of the hind femora being 

 very striking. The females, when resting motionless, greatly 

 resemble a grayish twig, which resemblance is considerably 

 augmented by the decidedly truncate abdomen." 



These specimens are of the same general size as individuals 

 examined from De Grassi Point, Ontario ; Vermont ; Norway, 

 Maine and " Penna.," but considerably smaller than a pair 

 from the cedar bogs of northern New Jersey. These latter 

 are enormous, considerably exceeding specimens of C. abdomi- 

 nalis in size. One female specimen, taken on pine, August 

 1 7th, belongs to the long- winged form called prima by Morse, 

 the tegmina and wings reaching slightly beyond the tips of 

 the posterior femora. 



Chloealtis abdominalis Thomas. 



Seven males. Pequaming, August 12 and 21 (meadow). 

 L,'Anse et Vieux Desert Reservation, August 20 (road along 

 lake shore), September 5 and 6 (meadow). 



' I took but seven specimens of this species ; all males. 

 They were taken in August and early September along the 

 lake shore. On September 5th two were captured while strid- 

 ulating on the top of some decked hemlock logs. They were 

 very spry, somewhat resembling in their movements and the 

 sounds which they produce the males of conspersa. More 

 specimens could easily have been taken." 



Mr. A. N. Caudell of the U. S. National Museum has very 

 kindly compared one of these specimens with males of this 

 species from the northwestern States, and finds them identical.
