ORTIIOPTEEA OF INDIANA. 415 



one drew near. Usually, however, it was at a distance from any 

 visible pit and would then leap vigorously when approached, often 

 to a height of five feet and a distance twice as great. By close search 

 it will probably be found to occur along damp sandbars in all por- 

 tions of the State, as its general range includes the United States 

 east of the Great Plains. 



LIII. Ellipes Scudder (1902). 



This genus was but recently separated from Tridaclijlus. The 

 main distinguishing characters are given in the key. But one spe- 

 cies, B. miiiuta (Scudder), ranging from Mmnesota to Cuba and 

 Mexico, and from Indiana to California, is known from the United 

 States.

 In Indiana this small sand cricket has been taken in Spencer, 

 Vigo, Putnam and Lake counties. It frequents damp aamiy places 

 which are sparsely covered with grass or other vegetation, where it 

 is often found in company with the grouse locusts or with the larger 

 sand cricket, Tridactylus apicalis Say. A^^iile more active in its 

 movements it does not leap as high nor as far as that species. The 

 best way to capture them, after discovering a colony, is to sweep 

 rapidly just above the ground with a net of cheese cloth or other 

 close meshed material. 



Sul)-faiiiil.v MYRMECOrHILIN.E. 



The Indiana members of this sub-family are very small, sub- 

 spherical crickets, which bear a general resemhlance to the young 

 of cockroaches but leap actively when disturbed. They live wdth 

 colonies of ants in or beneath rotten stumps and logs and under 

 sttnies. Tlicy belong to the single genus, MyriHCCophiki, character- 

 ized as follows:
