Elytra tawny, subhyaline, nervures white margined with brown, 

 appearing striped. An indistinct brown band extends from humeral 

 angles to the tips of elytra, interrupted by the pale nervures. Venter 

 black, margined with yellow; ovipositor and tips of male plates black. 

 Genitalia: Female last ventral segment as long as preceding, 

 longitudinally striated; posterior border slightly emarginate and nar- 

 rowly notched either side of middle; pygofers long beset with long 

 brownish bristles. Male valve broad, long, apex roundingly angled. 

 Plates short, broadly and convexly rounded, posterior half diverging to 

 a black rugose blunt point. Posterior half beset with many long white 

 bristles. 



Four specimens, a pair from Trout Lake, Sept. 7, 1916, and 

 two males from Ladysmith, Aug. 9, 1916, were swept from 

 sedges in low swampy ground. 



2324. Chlorotettix unicolor (Fh.) — Common and generally distributed. 



2326. Ch. spatulatus O. & B. — In northwestern localities. 



2327. Ch. tergatus (Fh.)— Throughout the vState. 

 2331. Ch. galbanatus VD. — At northwestern points. 



Chlorotettex borealis n. sp. 



(Figs. 32, 33, 34, 35.) 



Resembling C. vividus in shape, but slightly smaller and with 

 distinct genitalia. Length 5 mm. Much smaller than any 

 other known northern species. 



Vertex obtusely angled, slightly more than one-half longer on the 

 middle than next the eye, twice as broad as long. Anterior margin 

 of pronotum strongly convex; posterior margin slightly concave; 

 lateral angles broadly rounded. Elytra smoky hyaline. 



Color: Resembling C. vividus in color, more of grass green than 

 found in most species of the genus. Last ventral segment of female 

 with a dark median stripe from the apex of the incision to the base of 

 the segment. Ovipositor dark. Tibia and tarsi of front legs brownish. 



Genitalia: Female last ventral segment twice as long as preceding, 

 lateral angles well rounded. A rather broad median notch extending 

 half way to the base; sides convexly angled posteriorly. Male valve 

 twice as long, triangular with rounded apex. Plates rather long, 

 convexly rounded to rather blunt tips. Hairs mostly on margin and 

 dorsal surface. 



A pair were swept from grass in a clearing at Trout Lake, 

 Sept. 7, 1916. 



2336. Ch. lusorius O. & B. — At central and northern points.
