CHARLES W. HOOKER. 157 



It was originally described by Ashmead as a Thyreodon, but 

 he was not sure where it belonged as shown by his statement, 

 after the description, that "the large stigma might exclude it 

 from the genus Thyreodony Later (Transactions American 

 Entomological Society, Vol. 23) he states that T. texamis 

 belongs to the genus Eremotylus. The general character, 

 especially the shape of the radial and discocubital veins, the 

 nervellus broken well below the middle and the presence of 

 a stigma place it at once in the genus Eremotylus. It has 

 been confused with Ophion slossonce, but these two species 

 can be easily distinguished by their venation which is typical 

 of the two genera. It is apparently closely related to E. 

 infuscatus. 



Distribution. — Cypress Mills, Texas ; Moscow Mountains, 

 Idaho, July 8 ; Washington. 



This species seems to have a somewhat limited range in 

 the southern and western United States and northern Mexico. 

 It has been taken at Cypress Mills, Texas ; California; Mos- 

 cow Mountains, Idaho, and Washington. 



Nothing is known of the life history, habits or hosts of 

 this species.
