 Orthotylus translucens, new species. Colorado, Cheyenne canyon, near Colo- 

 rado Springs; July, 1894. 

 Elongate; minutely pubescent, more apparent on wing-covers than on 

 body; legs and antennae as well as the body uniform straw-yellow, 

 probably grass-green when fresh, same as thickened portions of wings, 

 which are mainly that color. Head rounded, smooth; eyes very promi- 

 nent, black, somewhat deep-set above and below, narrowing the ver- 

 tex, which has a faint triangular depression with the base formed 

 against a narrow transverse ridge on posterior margin of the head. 

 Tylus short and narrow, defined at base by a deep incisure between 

 antennal insertions; rostrum slender, reaching well between the mid- 

 dle coxae, black at extreme tip. First joint of antennae somewhat 

 stout, about as long as the vertical diameter of an eye; second joint 

 slender and nearly four times as long as the first; others missing. 

 The pronotum widens obliquely backward, the posterior margin having 

 nearly twice the expanse of the anterior which is about equal to the 

 length, all margins straight; the anterior lobes are slightly rounded, 

 the posterior ones curved and reflexed. Surface smooth and convex ; 

 a deep, narrow incision extends entirely across transversely just in 

 front of the middle, at the center of which is a deep notch that sepa- 

 rates two apparently large tumid callosities; collum compressed in 

 front. Scutellum equal in length and breadth, smoothly convex, but 

 divided into two unequal parts, the smaller basal portion being defined 

 by an incision extending across and curving into the anterior angles.
