ters, composed of two joints, the second a little the longer; pronotum short, 

 especially in the male, hardly more than half the length of the vertex; angles 

 prominent, posterior margin concave, subparallel to the anterior; surface 

 obscurely transversely striated. Scutellum longer than the pronotum. Elytra 

 narrowed toward the tip; costa uniformly arcuated from near the base to the 

 apex; appendix very narrow; nervures prominent, punctured, first sector 

 forked once at the basal third, where a transverse nervure unites it with the 

 simple second sector, thus forming one small basal, two long discal, and four 

 short apical areolets; costal areole broad. Clavus with two nervures, the 

 inner short and curved inwards to the suture, but little behind the point of 

 the scutellum; first two sectors of the wings united in one before their end; 

 third sector forked on its apical fourth and united to the second by an oblique 

 nervure; supernumerary cell present. Legs normal; basal joint of the pos- 

 terior tarsi exceeding in length the two following. 



Color: Male. — Head pale dull fulvous yellow, clearer on the central li:;e 

 of the vertex and near the ocelli; extreme tip with a small black point and 

 another adjoins each ocellus without; front with a brown longitudinal vitta 

 each side. Eyes black, pronotum dusky whitish, with three paler longitudi- 

 nal lines, the lateral somewhat oblique. Scutellum pale yellowish white, 

 with a short, oblique, brown line near each basal angle in continuation of the 

 inner claval nervure. Elytra subhyaline, dull subopalescent or milky-white; 

 nervures brown, dotted with white, paler at apex. Wings whitish hyaline, 

 iridescent; nervures brown and conspicuous. Beneath black, pectoral pieces 

 edged without with pale. Abdomen black, connexivum and edge of the 

 segments pale; apex of the genital pieces whitish. Legs soiled white, apex 

 of the tarsal joints and lower face of .the posterior tibiae embrowned. 



Female. — Head, pronotum and scutellum dull white, tinged with yellow; 

 frontal vittte pale salmon color, or sometimes wanting. Tergum and all be- 

 neath soiled white; base of the tergum, and occasionally a few spots on the 

 sternum, black; first two sectors of the wings pale and indistinct, otherwise 

 like the male. 



Genital pieces: Male. — Valve wanting, plates long, narrowed above to 

 the obtusely rounded tips; with a few scattering hairs. 



Female. — Last ventral segment longer than wide; apex straight, with a 

 minute central notch. Pygofers broad, not produced at the apex; a little 

 shorter than the ovipositor, fringed with a i'ew short hairs. 



Described from one male (No. 629) and two female (No. 277) 

 specimens. Superficially, this insect bears a marked resemblance to 

 Tettigonia tripunctata Fitch, although the two species are very dis- 

 tinct structurally. It differs fi-om the genus Jassiis as restricted by 

 Stal in the simple neuration of the elytra and the consequent less 

 number of apical areoles, the convex front, the narrower clypeus, 

 and the elongated antennal setae, and probably forms the type of a 

 distinct genus. It has much the form of Jassus gratiosus Span, as 

 figured by its author (Of. K. Vet. Ak. Forh. Vol. 36, No. 6, p. 25, 

 plate 16, fig. ID, 1879), but is shorter and differs by most of the
