 filled with succulent grasses at the head of gulleys. 



NEOCONOCEPHALUS RETUSUS (Scudder).2 



Churchland, September 15, November 4; Portsmouth, October 3; 

 Deanes, September 26; Franklin, September IS; Tappahannock, 

 August 21 (juv.), August 23 to October 2; Sharps, October 13.

1 Practically all the material included under this species appears to be intermediate between the typical 

 race and the subspecies crepitans. 



2 In the writer's article on New Jersey Orthoptera, p. 522, the records there included under Mops actually 

 pertain to retusus. Rehn and Hebard by their recent revision have rendered a great service to field 

 workers in clearing up the confusion in which this and several other related genera had previously been 

 involved (Trans. Amer. Entom. See, vol. 40, 1915, pp. 36&-413).
