Habitat. — Head of Pine Creek, Calgary, Alberta, July 21, 1900, 

 Mr. Dod (No. 31). 



This striking s])ecies was first sent me by Mr. Dod in December, 

 1900, and was returned to him as probably new. It was again sent 

 me in 1901, still unique, and is now described from the female only —

This species is robust, with quadrate heavy thorax, short triangular 

 wings, and is allied to chaitaria and defessa.
