houey yellow. Wing veins (except at base) and siiguia yellowish brown ; radius 

 indistinct; areolet very minute, triangular. Posterior coxte subcyliudrical, 

 nearly as long as abdomen. 



Described from seven specimens (two % , five 9 ) from Massachu- 

 setts in the collection of the American Entomological Society. 



At first sight this species has much the appearance of an AjxDiteles, 

 as the areolet is so minute as to be indistinguishable without con- 

 siderable maernification.
