212 THE CANADIAN ENTOMOLOGIST. 



Scutellum pale tawny and testaceous, in irregular motllings. Elytra 

 subhyaline testaceous, nervures scarcely darker except at apex, where 

 they are sometimes distinctly fuscous. Some specimens from the higher 

 altitudes lack the fulvous tinge, and have more distinctly fuscous 

 nervures. 



Genitalia : female segment rather long, slightly emarginate pos- 

 teriorly, with a strap-shaped median tooth, Male valve very obtusely 

 triangular, plates long triangular, about five times the length of the valve. 



Described from sixteen specimens collected at Fort Collins, Palmer 

 Lake and Rico, Colo., by the author. 



Eutettix bicolorata^ n. sp. — ^Form o{ jucunda nearly, slightly larger, 

 and with a more prominent front. Front pale greenish-yellow, with black 

 markings on pronotum and tips of elytra. Length, ? 6 mm.; width 

 nearly 2 mm. Males slightly smaller. 



Vertex rather narrow, but little wider than an eye, and only a trifle 

 longer in the middle. Surface sloping strongly to the transverse depres- 

 sion. Front much inflated, meeting the vertex at a slightly obtuse angle, 

 the margin distinct. As seen from the side the front is roundingly angled 

 below the antennui. Pronotum short, truncate behind. Elytra long, 

 narrow, compressed behind. 



Colour : vertex greenish white, four small dots on the anterior 

 margin, and an irregularly reticulate square of black in the centre of each 

 half of the disc. Face greenish white above, brown or fuscous below, 

 sharply separated on a line just below the eyes, the darker colour running 

 up on the sides to the antennal sockets. Pronotum heavily inscribed with 

 black, omitting a narrow posterior margin, a row of irregular spots 

 anteriorly, and three more or less definite stripes on the disc. Scutellum 

 inscribed with brown, omitting three spots in an apical triangle. Elytra 

 greenish straw colour back to the apex of clavus, the nervures concolorous. 

 Back of the clavus the elytra are milky white, with the nervures and 

 numerous reticulations black in sharp contrast. The apical portion of 

 this area solidly infuscate, omitting a marginal line and a small hyaline 

 spot in the third apical cell. 



Genitalia : female segment long, posterior margin slightly produced 

 in the middle and sinuate either side. Male valve short, transverse, plates 

 long-triangular, the apices extended and margined with fine white hairs. 



Described from one female from Hot Springs, Ark., H. S. Barber 

 collector (U. S. N. M. Coll.), and four specimens taken by the author at 

 B-ichfield, Utah.
