C. lusorius (Osborn and Ball). 



Proc. la. Acad. Sci., iv, 226, 1897. 



Vertex one-half longer on middle than at eyes. Olive-brown 

 with a faint crescentiform band between eyes. Brownish tinged 

 with red, especially on elytra. Female segment emarginate pos- 

 teriorly, with a broad, angular, dark-margined median tooth half 

 as long as acutely rounding lateral angles. Length 7-8 mm. 



Found on coarse grasses during July and August, but always in 

 open woods or sheltered areas. From collecting observations it 

 seems to be a woodland species.

C. nudatus Ball. 



Can. Ent, 32, 340, 1900. 



A large species of the genus with vertex twice longer on middle 

 than next the eyes. Pale green with some brownish areas on 

 pronotum, scutellum and elytra. Female last ventral segment with 

 posterior border dark margined, a notch at center and a shallow 

 emargination either side divides the segment into four lobes. 

 Lateral angles prominent. Male valve narrow, roundingiy angu- 

 late ; plates broad at base, three times the length of the valve, 

 gradually narrowed to acute, slightly produced tips,, 



A grass-feeding species with a southern distribution. The 

 collecting of this species in Connecticut establishes a very interest- 

 ing and unique record. It is apparently distributed along the 

 Atlantic cuastal area.
