214 ORTHOPTERA OF NOVA SCOTIA. PIERS. 



Camnula pellucida, Scudder. 



Clear-winged or Pellucid Locust. 



This sober-coloured insect occurs from Connecticut north- 

 ward, and has been reported from Quebec (Provancher) and is 

 common at Montreal (Cauifield). I have so far obtained but two 

 specimens, both females. The first was captured, September 5th, 

 1895, in company with Circotettix verruculatus in a stony place 

 near Block-house Pond, Halifax. The second was taken, 

 October 2nd, in a damp, grassy spot on the side of the road, 

 close to Cow Bay Bridge. When upon the ground, the species 

 somewhat resembles C. verruculatus. 



Dissosteria Carolina (Linnaeus). 



Carolina Locust. 



This locust is widely distributed, being found from the 

 Atlantic to the Pacific, and in the United States as well as 

 in Canada. It is the largest acridian occurring in Nova Scotia. 

 It frequents dry stony places and roadsides, and resembles in 

 colour the prevailing tint of the situation in which it occurs. 

 It is much less abundant than C. verruculatus which is found 

 in the same situations. The last individual noted in 1895 was 

 seen on September 28th. 



Circotettix verruculatus (Kirby). 



Very common in dry, warm stony places, in company with 

 the less abundant species, D. Carolina. During flight it produces 

 a loud cracking or clapping sound, which is familiar to all and 

 very suggestive of hot and dusty country roads. Although 

 resembling, when on the ground, the larger D. Carolina, it may 

 be readily distinguished when in flight the basal portion of 

 the wing being yellow in verruculatus , whereas in Carolina it 

 is black and the outer edge of the wing is yellow. In 1895 the 

 last specimen of verruculatus was taken on September 28th. 

 It appears about the end of July.* Six specimens of this insect 

 are among some Orthoptera collected by Mr. Marshall in the 



* In 1895, it was first noted on July 18th, and it was common on the 25th.
