 Grouse Locust. 



Typical examples of this race or form differ from typical crintaltin in 

 having the front margin of pronotum projecting more strongly over the 

 head and the median carina a little higher, more strongly compressed, 

 more evenly curved and often so thin in section that, when held againsr 

 the light, the punctuations of its surface appear translucent. Length of
