18 THE CANADIAN ENTOMOLOGIST. 



another pair on the base, a submarginal row on pronotum and a basal row 

 on scutellurn. Length, $ 6 mm., £ 5 mm. ; width, almost 2 mm. 



Vertex one-half wider than long, half the length of the pronotum, the 

 margins nearly parallel, the apex very slightly conically produced ; face 

 but slightly inclined, forming nearly a right angle with the flat, slightly 

 sloping vertex ; front broad below, abruptly narrowing to the clypeus ; 

 elytra rather broad, compressed behind, giving a wedge-shaped appearance 

 to the insect ; venation obscure, similar to that of Kennicotti. 



Colour : vertex yellow, sometimes washed irregularly with brown, a 

 pair of dashes on base of front visible from above, and a pair of round 

 spots at base black. Pronotum varying from pale or milky to olive fuscous 

 on the disc, the anterior fourth pale yellow, with an irregular band of black 

 spots. Scutellum yellow, with a pair of round dots between a pair of larger 

 triangles of black on the base. Elytra brown or brownish fuscous on the 

 disc, shading out to subhyaline towards the margins posteriorly, the 

 nervures lighter, the claval nervures milky, with the outer part becoming 

 broadly so towards the apex ; face pale yellow, a few brownish arcs on the 

 upper part of front below the black dashes, and sometimes a line on 

 clypeus. 



Genitalia : female segment nearly twice as long as the preceding, but 

 somewhat narrower, whole segment in the form of a parabolic curve, a 

 second membrane appearing from under the lateral margins and extending 

 back two-thirds the length of the segment ; male valve very obtusely 

 triangular, as wide but not over half as long as the apical segment; plates 

 large, broader than the valve at base, and over four times as long, 

 legularly narrowing from just beyond the base to the bluntly rounding 

 apices; margins thick and clothed with weak hairs. 



Described from eleven specimens from Los Angeles Co., Calif.; 

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



This species seems to combine in part at least the characters of two 

 different groups in Thamnotettix, for while in many ways it resembles 

 Kennicotti, in other characters it is allied to some of the green species. 



Errhomenellm irroratus, n. sp. — Smaller than inaculatus, which it 

 much resembles. Stouter bodied, and with a fuller front and more 

 rounding head. Dark brown, irregularly dotted with pale yellow.
