34 PROCEEDINGS MANCHESTER INSTITUTE 



August 2 and September 5, at Provincetown, Mass., West 

 Chop, M. v., and North Haven, Ct." 



One female in collection is bright reddish brown ; the males 

 are "chiefly blackish fuscous, marked with white." 



Bncoptolophus sordidus, with Dissosteira Carolina, belongs 

 to the ubiquitous type, and by the remarkable protection gained 

 from their ability to acquire, in general color, the particular 

 tint of soil which they inhabit, seem destined to hold fast their 

 numbers. 



Specimens of Psinidia fenestralis with orange-colored wings 

 were plentifully distributed, but none of the rose variety were 

 met with during the season, thus proving the latter to be the 

 exception. 



I was especially pleased to note the next named trim and cool- 

 looking locust as a resident species, though it was certainly not 

 rare in this locality, Circotettix verruculatus. To capture it 

 requires all the agility and patience of the Odonate enthusiast. 

 When at rest upon the rocks, it is so like in appearance to their 

 weathered surface that it is not easily discovered till startled by 

 your approach. After a short and zigzag flight, accompanied by 

 a loud crackling noise, it often alights in the path before 3'^ou, 

 but only to dissolve once more into the general color of the rock 

 so quickly that the eye cannot follow. 



Mr. Morse so aptly describes the haunts and mannerisms of 

 this species, that I again quote his description, — "It is found 

 plentifully in northern and western New Kngland, its favorite 

 haunts being bare ledges on elevated land and low mountains. 

 On these it delights to bask in the sunshine, crawling about over 

 the lichen-ccvered and weather-beaten rocks, with whose tints 

 its coloring harmonizes, or to hover in the air above them, sharp- 

 ly stridulating. Its 'song' in flight is the loudest produced by 

 any of our locusts, and consists of a series of separate notes, 

 clicks, or snaps, not a rattle, and is readily distinguished by this 

 peculiar snapping quality. It is one of the wariest of our lo- 

 custs, being especially shy and difficult to approach during the 

 warmer part of the day, when it often flies awa}' to a distance of 

 several rods and circles about, returning to the place whence it 

 started, or dances up and down in the air, snapping loudly."
