Thamnotettix ciliatus Osboni. 



l>ike other species of this group in the creniis the species occurs 

 in boggy places on sedge or coarse grasses. It is seldom taken 

 but very likely occui-s in abundance on a certain host plant at the 

 proper season. Cranberry Lake (Hedgehog Pond), Aug. 11, 1920.

Thamnotettix smithi Van Duzec. 



This sjiec'ies seems 1o be much less abundant than m-^htnogaster 

 to which it is closely related. It occui's in lo'v ground and in 

 marsh upon grasses and sedges; it may be restricted to a certain 

 species of fond plant and consequeiilly not oft( n collected.

Fairly common though not abundant on marsh grasses and 

 sedges of sAvamp meadoAV. Cranberry Lake. Ausr. 1, 1917; July 28.

Chlorotettix unicolor (Fitch). 



This form has been taken at many different locations and may 

 be considered as one of the important species of the region ; its 

 occurrence on grasses is sufficient to make it of economic impor- 

 tance where these grasses have any yalne. Both young and adults 

 live npon the grasses of the SAvarap meadows and form one of the 

 most conspicuous features of these associations. Cranberry Lake.

Chlorotettix lusoriiis fOsborn and Ball). 



This species occurs in mixed grasses and sedges and so far as 

 observed here prefers the higher locations but where there is con- 

 siderable moisture and shade. It is too rare to be of economic 

 importance. Barber Point. Aug. 5, 1920. Bear ^tountain, 

 Aug. 15, 1920.
