230 THE CANADIAN ENTOMOLOGIST. 



margin very slightly sinuate ; ovipositor long, slightly exceeding the 

 rather slender pygofers. 



Described from two females from Biscayne Bay, Fla., collected by 

 Mrs. Slosson. 



Thamnotettix Sherniani, n. sp. — Resembling cyperacea in general 

 appearance. Slightly stouter, paler, with a double-lined vertex margin 

 and a deltocephaloid venation. Length 5.25 mm.; width 1.5 mm. Vertex 

 flat ; anterior margin obtusely angular, definitely and slightly acutely 

 angled with the front, a third longer on middle than against eye, half 

 wider than long. Elytra rather long, but with the apex broader than in 

 cyperacea. Venation distinct, strong ; two cross nervures between the 

 sectors ; the central anteaj^ical cell long, constricted and divided beyond 

 the middle. Colour : pale tawny, iridescent over a subolivaceous 

 ground. Vertex pale tawny-yellow ; anterior margin white, narrowly 

 margined above and below with black, the black line above almost con- 

 stricted into six dots. Elytra subhyaline with a slight tawny iridescence. 

 Face pale tawny, below pale straw. Genitalia : female segment rather 

 long ; posterior margin nearly straight; the lateral angles prominent. 



Described from one female taken at Raleigh, N. C, by Prof. 

 Franklin Sherman, who sent a number of fine Jassid^ for determination. 



Chlorotettix rugicol/is, n. sp. — Resembling spatnlatus^ but with a 

 broader vertex. Green, with a red band on the margin of vertex. Length 

 7 mm. Vertex broad, obtusely rounding, but little longer on middle than 

 against eye, two and one-half times longer than wide, evenly rounding to 

 front. Elytra rather long, the veins large and distinct. Colour : pale 

 green, a transverse red band on margin of vertex and front, sometimes 

 extending over the eyes. The male has the elytra clouded with tawny 

 brown. Genitalia : female segment deeply triangularly excavated, with a 

 strap-shaped tooth, similar to that in spattdatns. Male valve nearly as 

 wide as the ultimate segment, and al)out half as long ; plates nearly flat, 

 long, triangular ; the margins sparsely haired. 



Described from four specimens : One female from Jacksonville, 

 Fla., from Otto Heidemann ; a pair from Woodbine, N.J., taken Aug. 

 2nd, 1902, by E. P. Van Duzee; and one female from Victoria, Tex., 

 received from U. S. Nat. Museum. The remarkably broad vertex with 

 the red margin will at once separate this from the other spatulate forms in 

 this group.
