14 SYNOPSIS OF THE GENUS CHLOROTETTIX 



Color: Almost uniform pale green, often washed with yellowish. 

 Disc of pronotum, basal angles and a median notch on scutellum 

 darker. Elytra hyaline, nervures often distinctly green in color. 



Genitalia: Last ventral segment of the female long, with a 

 rather broad, shallow notch, becoming narrowed and sharper at 

 apex; the edge of the lobe on either side more or less sinuate. 

 Male valve short and broad, almost truncated. Plates broad at 

 base, outer margins concave on apical half, apices moderately 

 produced, subacute, slightly divergent ; a few spines on margin ; 

 pygofers large, greatly exceeding plates. 



The species has a distribution from coast to coast through the 

 northern part of the United States and southern Canada. It has 

 not been recorded for a southern state. Specimens at hand from 

 Maine, New York, New Hampshire, Ohio, Wisconsin, Iowa, Ore- 

 gon and Washington, seem to show very clearly the distribution. 

 In addition to these states it has been reported for Colorado, 

 California, and the southern border of Canada. I have examined 

 specimens in the Osborn collection which were collected at Fitch's 

 home and compared with the types of this species in the Fitch 

 collection at Albany. 



Chlorotettix similis n. sp. 



Size and form of unicolor and resembling it very closely in 

 general appearance, but with head slightly longer at middle, and 

 distinct genitalia. Length, 6.57.5 mm. 



Vertex broadly rounded as in unicolor but distinctly longer at 

 the middle than next the eye. Width between the eyes more than 

 twice the length. Pronotum short and broad, more broadly 

 curved anteriorly than the anterior margin of the vertex. Elytra 

 as in unicolor. 



Color: Uniform pale green, unmarked; elytra greenish, 

 hyaline, nervures faint or indistinct. 



Genitalia: Last ventral segment of female longer and narrower 

 than in unicolor, more than twice as long as preceding segment, 

 and convexly narrowed, posteriorly, from about the middle. The 

 posterior margin is composed of two rather narrow, strongly 

 rounded lobes, formed by the median notch, the sides of which 

 are convexly rounded and, after meeting, often overlap along the 

 median line of incision. This incision extends one- third of the 

 way to the base. The whole surface of the segment is very rugose
