This is our largest locust belonging to the (Edipodina-. The 

 males are ready fliers, taking to wing upon being approached. 

 The female seldom flies up more than once and often escapes 

 notice by remaining quiet. The species is found in dry, bushy 

 pastures, on hillsides, or on light, uncultivated soils. The young 

 appear about the first of September, and are " curious little de- 

 pressed toadlike objects usually purplish leaden in color." This 

 species reaches the adult stage the last of April or the first of 

 May and is found until the latter part of July. Our earliest 

 record is April 28. Thompson, South Kent (A. P. M.) ; New 

 Haven, 4 May, 12 May, Oxford, 21 May, Rainbow, 24 May 

 (W. E. B.) ; New Haven, 17 June (E. J.^S. M.) ; Hamden 28

H. rugosus Scudder. 



This species is similar in size to tuberculatus. The vertex 

 does not extend so far in front of the eyes and is more rounded 

 at the connection with the face (Fig. 28a). The median carina 

 extends to the front and a cross carina divides the disk into four 

 nearly equal parts. Pronotum with the surface of the disk with 

 numerous oblong or elongated tubercles, the hind margin ob- 

 tusely angled. The disk of the hind wings usually pale yellow 

 but varying to orange. 



H. rugosus is very rare in New England and has not been 

 recorded from Connecticut. It has been taken in Norway, Maine, 

 and in Eastern Massachusetts. Scudder gives the distribution as 

 " U. S. east of the Rocky Mountains." It should be looked for 

 in localities similar to those inhabited by tuberculatus.
