BUFFALO SOCIETY OF NATURAL SCIENCES IOI 



base, confluently punctured in transverse rugas; humeral angles rounded, 

 not at all prominent; posterior process very narrow and acute at apex, but 

 little surpassing the apex of the clavus and abdomen; posthumeral sinus 

 shallow. 



Color pale yellowish, probably green in life; face with eight black 

 points: two adjoining each eye, two on the base behind the ocelli and one 

 either side of the clypeus; some or all of these may become ferruginous or 

 pale. Callosities forming a slender black line over the inner angle of each 

 eye. Elytra hyaline, nervures slenderly fuscous; nervures of the wing 

 fuscous and showing through the thin elytra. Tarsi tipped with black. 

 Length 7 mm. 



Arizona. Described from two females in the Cornell 

 University collection bearing the MS name given it by Dr. 

 Uhler and here adopted. This species is quite distinct from 

 any other known to me by its short depressed pronotum and 

 rugosely punctured surface. 



6. Ophiderma nigrocincta n. sp. PI. 2, fig. 29. 



Color testaceous white. Head sparcely punctured with black; the 

 sutures distinct; two minute points on the base of the vertex above the 

 ocelli, a more or less distinct line within the rectilinear apical margin of the 

 cheeks, and the sutures between the lorae and clypeus broadly, black. 

 Clypeus parallel-sided, long, smooth, much exceeding the small almost 

 triangular lorse, marked with a pair of minute black points at base. Meto- 

 pidium with a slender deep black submarginal basal line which is continued 

 around the humeral angles and is connected above each eye to an eroded 

 black arc. Pronotum with a distinct smooth median carina, becoming 

 castaneous or piceous behind the middle; this piceous area is broad, rather 

 vague anteriorly, is bounded either side by an oblique white vitta and is 

 crossed before the apex by a broad white band. Pale areas regularly dotted 

 with deep piceous punctures. Elytra hyaline; exposed base of the clavus 

 and basal two thirds of the very narrow costal areole coriaceous and punc- 

 tured; nervures strong, white basally, fuscous toward the apex. Legs and 

 chest more testaceous, the former lined with brown, and with the tips of the 

 tibiae and the tarsi black. 



Described from one female taken by me near Maniton, 

 Colorado, August 2d 1900.
