proiiotuin. The later aboiit as broad as long, a little constricted in 

 the middle, roundly advanced upon the occiput, the hind margin 

 widely and roundly angulated, the posterior lobe plainly shorter 

 than the anterior one and flattened on the disk, the median carina 

 fairly prominent and eut by ail three transverse sulci. Tegmina 

 provided with rather strong longitudinal veins and few cross-veins, 

 about reacliiiig the apex of the abdomen, a little tapering, he apex 

 ruunded. Hind femora moderately robust, evenly tapering, as long as 

 the abdomen, the genicular lobes acuminate; hind tibiae with the 

 base l'olnist, beyond somewhat undulate, with weak spines, eight 

 internally and seven exterually; hind tarsi long, slender and hairy, 

 the three joints almost equal and taken together nearly or quite 

 three-fourths the length of the hind tibiae. Prosternai spine very 

 coarse. short and blunt, wart-like. Last ventral segment short, 

 wedge-shaped; cerci broad at base, suddenly narrowing one-half from 

 above, curved backward and inward, the apical third flattened and 

 obliquely docked, the apices touching: supraaual plate small, provi- 

 ded at base with a median longitudinal sulcus. 



General color of abdomen, tegmina, under side and legs dark 

 olive-green, head, pronotum and pleura black. Face inside of late- 

 ral carinae raarked with four patehes of dirty or creamy white, two 

 above, two below, face outside of carinae and cheeks immediately 

 below the eyes likewise marked with white, as are the middle of 

 the sides of the pronotum near the front and hind raargins and the 

 middle of lower margin, while the lateral edges of the disk in the 

 locality where the lateral carinae would be if présent, similarly pallid. 

 In addition the pleura below the closed tegmina and the hind fe- 

 mora are also conspicuously marked with white, on the latter above 

 and externally near the base at middle and pregenicular; the hind 

 tibiae dark gray or plumbeous with a basai pallid annulus, the tarsi 

 paler. Anterior and middle legs distinctly annulate. Wings faintly 

 blue, clouded and with dark veins. Antennae basally pale, infus- 

 cated beyond.
