THE CANADIAN ENTOMOLOGIST. 17 



Described from rive specimens from Fort Collins, Colo., collected by 

 Mr. Van Duzee and the author, and two males from the National 

 Museum, one from Santa Clara Co., the other from Los Angeles Co., 

 Calif., both collected by Coquillett. 



The longer and more pointed vertex will at once separate this from 

 any of the numerous varieties of belli, montana and geminata. 



Thamnotcttix bullata, n.sp. — Somewhat resembling chiragrica, smaller 

 and with a narrower head, irregularly pale and fuscous, a pair of large 

 black spots against the eyes in front; elytra with the nervures broadly 

 light. Length, 5 mm. ; width, 1.6 mm. 



Vertex two and one-half times wider than long, half the length of the 

 pronotum, but little longer on middle than against eyes, roundingly con- 

 fused with the inflated front, which is broadest across the antennal sockets 

 and abruptly narrows to the clypeus. Elytra considerably longer than 

 abdomen, almost parallel margined, apex obtusely rounding, appendix 

 narrow : venation distinct, the nervures broad, the central anteapical cell 

 extending beyond the other two, and slightly constricted in the middle half. 



Colour : vertex pale orange, four dashes on the apex of vertex and 

 front, anterior pair the larger, and a pair of large round spots occupying 

 the entire space between the ocelli and the eyes, black. Pronotum 

 cinereous or milky, more or less irregularly blotched with fuscous ; 

 scutellum pale yellow, with two large triangular spots within the basal 

 angles. Elytra sprinkled with brownish fuscous, the nervures broadly 

 white, emphasized on some of the cross nervures ; face pale yellow, a few 

 arcs on front brown ; antennal sockets and narrow sutural line black ; 

 legs and below pale yellow, the ovipositor black. 



Genitalia : female segment about half longer than the penultimate, 

 the posterior margin slightly emarginate on either side of a broad median 

 lobe that about equals the slightly acute lateral angles. 



Described from three females from Los Angeles Co., Calif.; Coquillett 

 collector. Received from the U. S. Nat. Museum. 



This is another of the broad-headed species of Thamnotettix, which 

 like atridorsiun and chiragrica are not typical of the genus, and at the 

 same time do not seem to be well placed in Athysanus. 



Thamnotcttix languida, n. sp. — Form of Kennicotti and Coquillctti 

 nearly, but with a longer vertex and broader form. Darker than Kenni- 

 cotti, with a pair of black spots just over the margin of the vertex and
