THE CANADIAN ENTOMOLOGIST. 



Vertex roundingly angular, the apex conical, scarcely two-thirds as 

 long as its breadth at base, half longer than against eye ; disc convex, 

 rounding to the front except at apex; front broad, rather flat; clypeus 

 broadest just before the rounding apex. Pronotum a little over half 

 longer than vertex; elytra rather stout. Venation peculiar, resembling 

 iongula, except that the outer anteapical cell is pointed and petiolate 

 anteriorly and the outer fork of first sector is very faint. Male smaller 

 and with a blunter vertex. 



Colour : pale yellowish olive ; the female has two large spots 

 within the basal angle and two smaller ones on the disc of the scutellum 

 and the cross nervures between the sectors brown. Elytra with slight 

 reddish cast. The males have no marking on scutellum, the elytra are 

 distinctly embrowned, especially along the claval and apical areas. In 

 both sexes there are a number of oval subhyaline areas. In the males 

 there are three approximate pairs along the sutural margin. 



Genitalia : ultimate ventral segment of female half longer than 

 penultimate, the lateral angle rounding, the posterior margin triangularly 

 emarginate from the lateral angles half way to the base ; from the bottom 

 arises a strap-shaped tooth equalling the lateral angles ; male valve 

 broadly evenly rounding. The plates, concavely, triangularly acuminate, 

 about twice the length of the valve. 



Described from one female and three males from Rifle, Durango and 

 Colorado Springs, Colo. 



SCAPHOIDEUS BLANDUS, II. Sp. 



Form and general appearance of j'ucuudus, smaller and paler, lacking 

 the reddish tinge of that species. Costal margin of elytra with numerous 

 regular cells. Length, 5 mm.; width, 1.10 mm. 



Vertex right-angled back to the eyes, which round off, not quite 

 as long as its basal width, disc flat, margins straight, vertex and face 

 forming an acute angle ; front, margins straight, clypeus very slightly 

 broadened below. Pronotum as long as vertex, more than half of its 

 length within the curve of the vertex. Elytra, claval veins but slightly 

 curved apically, usually a cross nervure from outer one to suture and often 

 several irregular ones between the veins, outer anteapical cell usually 

 with one cross nervure to the costa, sometimes several, costal margin 

 with numerous, indistinct, almost equidistant nervures which are perpen- 

 dicular to the margin.
