 at middle than next the eye. 



Color rich brown, vertex yellow in front land brown on posterior half, 

 face yellow, tinged with brown with two conspicuou'S black round spats 

 close together and close to the border of vertex ; pronotum, scutellum 

 and eyltra solid brown with no traces of yellow lines, the elytra becoming 

 semi -trans pa rent at apex. Beneath yellow with the lasit ventral segment 

 and pygofers brown. 



Genitalia : female, last ventral segment long, evenly rounded and 

 siiin5)le on hinder border. 



This form has been taken on several occasions and does not seem to 

 show any intergradation with belli in color pattern but it agrees so 

 closely in genitalia and in size and form that until males or a larger 

 series of individuals is in hand it seems best to consider it as simply 

 a variety. Specimens have been taken at Orono July 8th and 29th, 1913 

 and July 3rd, 1914. 



Thamnofetti.v chlamydatus Prov. 



Athysanus chlamydatus Prov. Pet. Faune Ent. Can. Ill, p. 339 (1890). 

 Thamnotettix infuscata Gillette and Baker. Hemip. Colo. 98. 

 Thamnotettix punctiscuta Gillette and Baker. Hemip. Colo. p. 99. 



Brownish with a greenish olive tinge especially when fresh. Scutellum 

 with two distinct dark spots. Length 5.5 mm. 



This was fairly common at Orono being taken on several occasions 

 June 3 and 30, July 7, 8, 9, 29, Aug. I and 7 and at Mt. Katahdin Aug. 22. 

 Some of the specimens were swept from, birch and hazel and the latter 

 particularly seems likely to be its food plant. 



This species was described from Canada and Colorado and has been 

 recorded from Sault Sfce Marie, Mich., Lake Placid, New York in the 

 Adirondacks, and these records for Maine gives it a considerably wider 

 range though still limited to the distinctly northern fauna. 



Thamnotettix melanogaster Prov. 



Jassus melanogaster Provancher Naturaliste Canadienne IV, 378, (1872). 

 Thamnotettix melanogaster Prov. Pet. Faun. Canad, HI, 284, (1890). 



Bright yellow, often tinged with orange, the border of the vertex 

 with four distinct black spots in a row ; venter black as also the tergum 

 of abdomen. Length 5 mm. 



This, is a quite common species in low ground occurring on coarse 

 grasses and sedges. It was taken at Orono Aug. 2, North Harpswell 

 Aug. i2th, Mt. Katahdin Aug. 22nd and at Ft. Kent Aug. 28th. It is 

 occasionally found in sufficient abundance to be counted injurious to the 

 grasses on which it occurs.
