80 THE CANADIAN ENTOMOLOGIST. 



irregularly irrorate and sparsely reticulate with brownish-fuscous. The 

 reticulations are gathered into several more or less definite spots along 

 posterior half of costa and one in the inner anteapical cell. The clavus 

 and adjacent parts of corium with a number of irregular translucent ivory- 

 white areas. Face finely irrorate in the male, sparsely so in the female. 

 Genitalia : Female segment short and truncate, slightly medianly 

 carinate, pygofers short and stout ; male : valve long, roundingly pointed, 

 the lateral margins concave at base, plates together equilaterally triangular, 

 twice the length of the valve. 



Described from three specimens from " Chads." Utah. A male from 

 Arizona and a female from California probably belong here, but are not in 

 shape to definitely determine. 



Phiepsius tigrinus, n. sp. — Resembling tubus and U/i/eri, but larger 

 and darker. Tawny brown, with sparse reticulations on elytra. Length, 

 °J 6 mm. 



Vertex three times wider than long, slightly sloping, the posterior 

 margin elevated, anterior margin rounding in front, almost parallel with 

 posterior one; apex scarcely produced. Front broad, the margins almost 

 straight. Pronotum smooth. Elytra moderately long, distinctly flaring. 

 Colour : Vertex tawny fulvous, pronotum tawny brown, with the 

 anterior margin shading to the colour of the vertex, and the disc irrorate 

 with milky white. Scutellum pale yellow, the basal angles irrorate with 

 tawny, and the apical third shading to ivory-white. Elytra very sparsely 

 reticulate and closely, finely irrorate with tawny. The irrorations omitting 

 a few irregular areas. 



Genitalia : Female segment broad and short, about twice the length 

 of the preceding, the posterior margin slightly emarginate, with the median 

 third weakly produced and dark margined. 



Described from a single female from Washington, D. C. This species 

 shows traces of the banding of Uhleri, but is easily separated by the 

 larger size and distinct genitalia. 



Eutettix (Mesamia) illumina, n. sp. — Short, stout, black, with a 

 hyaline band before apex of elytra. Length : ^ 4 mm. 



Vertex hardly twice wider than long, anterior margin slightly more 

 rounding than posterior, disc slightly sloping to the definite anterior 

 margin. Front convex, broad above, margins straight, narrowing to
