vertex by a space only a trifle greater than the diameter of the second 

 antennal joint, the fastigium of the vertex depressed in front, some- 

 what broader at its base than the length, the anterior edge broadly 

 truncate. Frontal costa prominent above between the antennee, al- 

 most twice the width of the vertex, its surface coarsely punctulate, 

 below the ocellus narrowing one-half and sulcate, continuous to the 

 clypeus. Antennae filiform, moderately coarse, a little longer than the 

 hind femora. Front sloping to the rear. Pronotum short, the hind 

 lobe shortest, and with its sides a little divergent caudad; hind margin 

 subtruncate, the anterior edge at middle widely and shallowly emar- 

 ginate. Tegmina and wings about a fifth shorter than the abdomen. 

 Legs rather robust, the anterior and middle pairs with inflated femora, 

 the hind pair also rather robust; the hind tarsi and tibia? lengthly and 

 rather profusely hirsute, the former with the three joints about equal 

 in length. Prosternal spine bullate, large, hairy. Last ventral seg- 

 ment of the abdomen of the male somewhat longer than wide, its 

 apex blunt, entire; cerci broad at base, emarginately and roundly nar- 

 rowed from above to one-fifth the basal width, and then bowed in- 

 wards and expanding into a rounded, banner-like, gently hollowed 

 spoon, as wide across as the basal width of the cercus. 



General color of insect dark wood-brown tinged with olivaceous on 

 the sides and the disc of the pronotum, the tegmina, cheeks, pleura, 

 and upper side of abdomen; legs somewhat paler, the hind femora 

 showing traces of two fuscous transverse bands above, cheeks below 

 and back of the eyes, middle of sides of the pronotum and pleura 

 showing dim traces of pallid maculations; genicular arches, inner 

 genicular lobes and bases of hind tibia? infuscated; outer margin of the 

 banner-like apex of cerci bordered with black; antennae dark fer- 

 ruginous. 



Length of body, cf , 20 mm.; of pronotum, 3.5 mm.; of tegmina, 

 12.5 mm.; of hind femora, 10 mm.
