Thamnotettix belli Uhl. 



Jassus belli, Uhler, U. S. Geol. Survey Bull. Ill, 471, 1877. 

 Thamnotettix belli Van Duzee, Psyche VI, 306. 



This a small light yellow species with oblique lines on the elytra and 

 a distinct yellow band across head and pronotum. Two small round 

 black spots on front next vertex. Length, 5 mm. 



This is a western species described from Colorado and apparently 

 common there. Van Duzee gives its distribution as Colorado, Canada, 

 Mich., and in my New York list a single specimen was referred to this 

 species though not agreeing entirely with western specimens. Three 

 specimens collected at Orono by Mr. Shaw June 6th, July 7th and i8th 

 extends its distribution into Maine and shows that it occurs early in 

 the summer and one of the specimens is marked from "Hazel." These 

 sipecimens agree well with Colorado specimens in my collection. Also 

 Mt. Katahdin 3000 ft. Aug. '02 (Barber). 



Thamnotettix belli var brunneus n van 



Similar to belli in size and form and in female genitalia but without 

 the black spots of vertex and with no yellow band on pronotum or 

 yellow lines on elytra. Length 5 mm.
