THE CANADIAN ENTOMOLOGIST. 307 



Thamnotettix guttiirosa, n. sp. 



Resembling dissimiiata female in general appearance, stouter and 

 shorter. Brown, with a short head and numerous supernumerary vein- 

 lets on the elytra. Length, male, 6 mm. 



Vertex broad, short, almost parallel margined, the apex a trifle 

 advanced, twice wider than long, disc almost flat, the margins broadly 

 rounding to the moderately covex, slightly inclined face. Front slightly 

 produced, as wide or wider across antennae than at base, then narrowing 

 to the broad truncate apex. Pronotum broad and short, but little longer 

 than the veitex. Elytra broad, inclined to be flaring, veins distinct, vena- 

 tion apparently regular, strong, with a number of supernumerary trans- 

 verse veinlets along the claval suture and in the anteapical and basal por- 

 tion of apical cells. In both of these examples a veinlet forms " the 

 second cross nervure," although blighily variable in position. 



Colour : Vertex pale yellow, washed with testaceous, traces of a pair of 

 round spots at base and a transverse crescent on the disc. A black spot 

 against either eye in line with the ocelli, a dash beneath each ocellus and 

 another on apex black ; these latter being parts of a reflex frontal arc. 

 Face rusty or tawny brown, with frontal arcs and sutures darker, a pair of 

 dark spots above the antennse. Pronotum cinereous. Elytra cinereous, 

 inclined to be smoky, the veins light, heavily margined with fuscous, 

 especially in the supernumerary cell?, which are sometimes entirely 

 fuscous. 



Genitalia : Male valve obtusely roundingly triangular; plates largci 

 leathery, roundingly narrowing, one-third their length, then nearly parallel 

 margined to the broad truncate tips, longer than their basal width and 

 entirely concealing the pygofers, their lower surface sparsely clothed 

 with hairs. 



Described from two males from Beaumont, California, collected by 

 the author. 



Thamnotettix ursbia, n. sp. 



Resembling dissimiiata female in general form and colour, smaller 

 and slightly darker, sexes alike in colour. Length 6 mm. 



Vertex definitely obtusely angled, twice wider than long, the disc 

 depressed, the margin broadly rounding to face. Front moderately wide, 

 regularly narrowing to the truncate apex, one-third longer than its basal 

 width. Pronotum longer than the vertex. Elytra long, almost parallel 

 margined, the apical cells rather short. Venation regular, with the outer 

 apical cell rather short and unusually broad. LTsually ^ number of super- 

 numerary veinlets to costa and occasionally a forked apical.
