reaching distance and flies rapidly for 

 many rods. Even when marked down 

 it is very difKcult to see, owing to its 

 close resemblance in color to the sand 

 on which it alights. I know of but one 

 locality where it is found away from 

 the sound of the surf, — this is at North 

 Haven, Ct., where it occurs sparingly 

 on barren sandy wastes. 



I have taken adult specimens on July 

 24, and Mr. Henshaw found it plen- 

 tiful on Nantucket Id., on Sept. 23. 



It is found on the shore of all the sea- 

 board New England States. I have 

 seen specimens from West Beach, Me. 

 (5 nymphs, M. C. Z.) ; Hampton, N. 

 H. (Scudder) ; Salisbury Beach, Mass. 

 (A. L. Babcock) ; and have taken it 

 at Provincetown and West Chop, M. 

 v., Mass. ; Watch Hill and Block Id., 

 R. I. ; Niantic, North Haven, and 

 Stamford, Ct.

This is an easily recognized species, 

 the only one likely to be confused with 

 it being Spharagevion saxatile from 

 which it may be distinguished by the 

 narrow wing-band, enlarged radial 

 veins, pale hind tibiae, and distinctly 

 two-notched pronotal carina. In color 

 it varies from a dark gray or brown to 

 black sprinkled with ashy, darkest on 

 the head and pronotum, palest on base 

 of hind thighs, and with the tegmina 

 indistinctly trifasciate. Occasionally 

 specimens occur light yellowish-brown 

 or ashy in color but as a rule the spe- 

 cies is the (.larkest colored of all our 

 locusts. 



It is found plentifully in northern and 

 western New England, its favorite 

 haunts being bare ledges on elevated 

 land and low mountains. On these it 

 delights to bask in the sunshine, crawl- 

 ing about over the lichen-covered and 

 weatherbeaten rocks with whose tints 

 its coloring harmonizes, or to hover in 

 the air above them, sharply stridulating. 

 Its '• song" in flight is the loudest pro, 

 duced by any of our locusts, and con- 

 sists 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 

 locusts, being especially shy and difficult
