Genus CoRYCOMiMA Karsch. 



Corycomima K.a,rsch, Stett. Ent. Zeitschr., LVII, p. 343 (1896). 



This is still another genus, which is peculiar to the African tropics. 

 It is also monotypic, so far as at present known.

Suborder GRYLLOTALPOIDEA. 



Among the saltatorial orthoptera none are more interesting than 

 the insects known as "mole crickets." These, on account of their 

 structure and burrowing habits, differ quite remarkably from their 

 allies, the true crickets. Mole-crickets on account of their aquatic, 

 or subaquatic, habits are confined to humid regions, where they may 

 be obtained by digging for them at the margins of streams and by 

 beating or sweeping the sandy beaches and rank vegetation growing 

 in such localities. 



These insects have usually been included with the crickets, but the 

 present writer prefers to set them aside as a distinct suborder with 

 affinities to both the locusts and the crickets. There are much fewer 

 forms in this suborder than are found in other groups of orthopterous 

 insects. This is probably due to their somewhat restricted distri- 

 bution, due to their burrowing and moisture-loving, or subaquatic, 

 habits.
