 tinctly elevated wider than high, 4.

 ruptly elevated above the posterior and frequently in- 

 clined forward, 4, Heliria Stal.

Genus Carynota Fitch. 



This genus may be distinguished from Ophiderma pri- 

 marily by the oblong, non-stylated terminal areole of the wing 

 and also by its having the dorsum longitudinally arcuated with 

 more or less of a sinus posteriorly, at least in the more typical 

 species. In porphyrea and its allies there is a distinct impres- 

 sion on either side behind the humeral angles and in this 

 respect they approach Cyrtolobus in that group of species I 

 have called Xantholobus. Carynota muskokensis is a more de- 

 pressed species and approaches Ophiderma. As pointed out by 

 me in 1890, (Psyche V. p. 391), Dr. Stal was mistaken in plac- 

 ing this genus as a synonym of Ophiderma. I would however 

 consider it identical with Optilete Stal, the type of which, 

 porphyrea, is I believe congeneric with mera the type of Cary- 

 nota. Our species may be located by the following key: 



Ground color testaceous grey; apex of the pronotum and a 

 transverse band behind the middle brown. 



1, mera Say. 



Ground color rufous to dark chestnut brown, 1. 



1. Dorsal line of the pronotum regularly but feebly arcuated 

 for its whole length ; color dark chestnut brown, obscure- 

 ly and irregularly dotted with yellowish with a somewhat 

 larger triangular spot on the middle of the lateral mar- 

 gins; lateral compression very slight,
