on the Missouri by A. W. Lindsey, and presented to me by Prof. H. 

 F. Wickham, has been identified as Okanagana riniosa. This insect 

 fits Say's description in every particular. The uncus is slightly more 

 pinched or ridged on the dorsum, also the cleft at the extremity is 

 somewhat deeper than in the males of Okanagana novehoracensis 

 (Emmons) from New York and Maine, but in other particulars it 

 appears to be the same. It is probable therefore that noveborascensis 

 is the same as rimosa, certainly not more than a variety. 



The fore wings in rimosa and canadensis (Provancher) are pro- 

 portionately narrower than in any of the other species considered and 

 in this particular the two Okanaganas that extend to the northeastern 

 United States and eastern Canada, can thus be separated from the 

 more western forms, tristis Van Duzee, excepted.
