PSYCHE. 



[September 1S97. 



are red-winged. While much collect- 

 ing needs to be done before one can feel 

 certain, I believe that it will be found 

 that the red-winged form is most com- 

 mon in the warmest parts of New 

 England. 



This is a common and widely distrib- 

 uted species, occurring nearly every- 

 where on sandy spots in southern New 

 England, and probably throughout the 

 entire district. On the seashore it is 

 sometimes associated with T. viari- 

 titna. It is usually plentiful where it 

 occurs, though often very local in con- 

 sequence of its habitat. When dis- 

 turbed it flies for but a short distance, 

 often only a few feet, the male produc- 

 ing a very slight, scarcely noticeable, 

 crepitation. 



I have taken it on various dates from 

 July 17 to Oct. 7 at Fryeburg, Me. ; 

 No. Conway, N. H. ; Provincetown, 

 Revere, Sherborn, and Wellesley, 

 Mass.; Watch Hill, R. I.; Canaan, 

 Montville, Niantic, Stamford, and 

 Thompson, Ct. ; and offshore on 

 Martha's Vineyard, Penikese, and 

 Cuttyhunk Ids. Mr. Henshaw has 

 found it common on Nantucket in late 

 Sept., and it has been taken at Nor- 

 way, Me., by Smith (M. C. Z.).

An easily recognized species, not 

 likely to be mistaken for any other 

 occurring with us. The sides of the 

 pronotum vary considerably in the 

 degree of prominence of the angulation, 

 sometimes being almost rounded, some- 

 times with a distinct, tooth-like projec- 

 tion. In color it varies with the soil of 

 the locality, the ground-color ranging 

 from white to light brown, more or less 

 sprinkled with dusky blotches ; these 

 are sometimes nearly obsolete, and 

 again nearly confluent on the head, pro- 

 notum, and base of tegmina. Specimens 

 from North Haven, Ct., show numer- 

 ous bright rufous fleckings, agreeing 

 with the reddish color of the soil at that 

 place. This variation in color is often 

 marked even in a small area, as I 

 noticed at Block Id. where a portion of 

 the beach is much darker than the rest, 

 and the locusts frequenting that part 

 agreed with it in tint. 



This is a common species along the 

 sandy sea-beaches of southern New 

 England, but while common it is one 

 of the wariest and most difficult to cap- 

 ture of all our locusts. Extremely shy, 

 it starts up befoie the pursuer is within
