Thamnotettix morsei Osborn. 



A single specimen of this species has been found and its associa- 

 tion is not known. Barber Point, Aug. 1, 1917. 



Thamnotettix eburatus Van Duzee. 



Only one locality, east from Barber Point, Ang, 11, 1920. is 

 noted for this species and it is evidently quite rare. Its food 

 plant is evidently the sweet gale as no other plant has been recog- 

 nized in connection with it. 



Thamnotettix belli (Uhler). 



This is a northern and western species and not heretofore 

 recorded for New York State. It has been recognized as most 

 abundant in the Rocky Mountains. It occurs especially in wood- 

 land on undergrowth and this is considered as its definite habitat. 

 Cranberry Lake, Aug. 1, 1917. Wanakena, July 15, ]920. Grasse 

 River, July 22, 1920. 



Thamnotettix belli var. brunneus Osborn. 



This variety was described from Maine and has the same general 

 association as the preceding species but differs particularly in the 

 coloration. Wanakena, Aug. 1-7, 1917. 



Thamnotettix waldanus Ball. 



This is an inhabitant of the deep Avoods and has been found only 

 on undergrowth in a dense forest and must be considered as 

 restricted to this association. It was taken Aug. 29, 1920, 

 especially among ferns but where maple ^;eedlings and some other 

 plants were present and it was hard to be certain of food plant. 



Thamnotettix chlamydatus (Piovancher) 



This species has usually been taken on 'ihe borders of thickets or 

 forest and was found along a woodland roadway on underbrush 

 but its food plant is not definitely known. Plains, Aug. 3, 1920. 



Thamnotettix pallidulus Osborn. 

 Cranberry Lake, July 17, 1920. 



Thamnotettix cypraceus Osborn. 



Differs from the typical form in lacking the tawny stripes on 

 head and pronotum. Plains, Aug. 3, 1920. 



Thamnotettix melanogaster (Provancher). 



This is a very common species throughout the eastern part of- 

 the U. S. and found in patches of sedge or swamp grasses. Sedges 

 are probably the usual host plant. Cranberry Lake, Barber Point, 

 Julv and Aue-. Grasse River, July 22, 1920.
