THE CANADIAN ENTOMOLOGIST. 201 



biack margined vertex. Straw yellow, with venation and margin of elytra 

 light. Length, 3.5 mm. 



Vertex almost flat, slightly transversely convex, a trifle shorter than 

 its basal width. The anterior margin broadly obtusely angled, vertex and 

 front meeting in an acute angle, the margin subacute. Front resembling 

 Osboj'fii, in general form, slightly more convex. Pronotum as in Osborni, 

 slightly shorter ; elytra as in Ciirtisii, scarcely longer than the abdomen ; 

 venation distinct, regular, resembling Curtisii except that the outer apical 

 veinlets are decidedly curved. 



Colour. — Almost uniform bright straw yellow, vertex with the margins 

 light, a broad black band just back of the anterior margin, pronotum vvith 

 a narrow, light, median band. Elytra with the nervures and margins 

 light, the ground color intensified against the broader veins and margins. 

 Face pale, a black spot on the clypeus, front fuscous with a median stripe, 

 the upper margin and about six pairs of short arcs pale yellow. 



Genitalia. — Female segment short, scarcely one-third as long as its 

 basal width, posterior margin slightly broadly emarginate, disc of the 

 segments slightly tumid at the apex of emarginations and brown margins, 

 giving the appearance of a broad median tooth. 



Described from three females from Texas, one of which was received 

 through the kindness of E. V. A^an Duzee. The black band on the vertex 

 margin renders this quite distinct in our fauna. 



Deltocephalus fraterfius, n. sp. 



Y^^%tvi\\)\\x\g pectmaiits, but larger and darker, with shorter, less flar- 

 ing elytra, ashy gray, with large quadrate spots on vertex and pronotum 

 and the margins of the elytral cells fuscous. Length, $ 4 mm. ; 

 $> 3-5 mm, 



Vertex long, acute, resembling pecti?iatus, bat much longer, as long 

 as in areolatiis. nearly tv.'ice as long as the pronotum, disc flat, the mar- 

 gins straight to the blunt tip. Pronotum short, transverse, set well into 

 the concave posterior margins of the head. Elytra shorter, less flaring 

 than in pectinatus. The ai)ices inclined to be narrow, rounding and 

 appressed, exposing the last abdominal segment in both sexes. Venation 

 similar \.o pcctiiiatus, the claval nervures irregular and usually tied to the 

 margins, central anteapical cell divided, often into four cells, in which 

 case the posterior three are small and nearly circular, usually four reflexed 

 veinlets to the costa.
