Glossonotus Butler. 



The characters of this genus are entirely artificial, being based 

 on the position and form of the pronotal crest which unfortunately 

 is much inclined to vary. Theoretically this crest is tongue-shaped, 

 erect, and placed well forward. Four species are recorded from 

 Connecticut.

Common. A large attractive species recognized by the long 

 slender horn which inclines slightly forward, uniform in width 

 and not expanded at the tip, and the white dorsal vitta extending 

 down the posterior median dorsal line. The tegmina are smoky 

 hyaline, clouded with brown at the tips and sparingly punctate at 

 bases and along margins of veins. 



The life history has not been worked out. Mr. Woodruff 

 reports that he has taken the species in Connecticut on black oak 

 and chestnut and also on yellow birch near a chestnut woods. 



Hosts: Hazelnut, swamp white oak (Quercus bicolor), hickory, 

 black oak (Q. velutina), chestnut, yellow birch.

Apparently the most common species of the genus in Connecti- 

 cut. Mr. Woodruff reports it most abundant on red oak but has 

 taken it also on white oak, chestnut, and on yellow birch growing 

 near chestnut. 



A short, heavy-bodied species, usually chocolate-brown in color 

 but sometimes grading into darker browns, with a broad whitish 

 or yellowish vitta down the posterior dorsal median line. The
