one-half the diameter of the first antennal joint. Antennae moderately 

 large and heavy, regularly ensiform, the basal half triquetrous, some- 

 what exceeding the head and pronotum taken together. Frontal 

 costa quite prominent, its sides parallel, sulcate throughout, the 

 ocellus large and situated below the middle. Pronotum cylindrical, 

 closely, regularly, and quite deeply, punctulate, both the anterior 

 and posterior margins broadly rounded, the median carina plainly 

 visible throughout ( 9 ) or interrupted on anterior lobe (cf ). Tegmina 

 and wings long, narrow, acuminate, greatly surpassing the apex of 

 both the hind femora and the abdomen. Hind femora slender, their 

 apex extending a trifle beyond the outer margin of the fifth abdominal 

 segment; hind tibiae slender, but little expanded apically, the outer 

 margin bearing eight to nine spines, which are somewhat irregularly 

 arranged. Subgenital plate, or last ventral segment of male abdomen, 

 somewhat elongate and tapering, the apex emarginate and terminating 

 with short, blunt, lateral teeth; the contorted process above of 

 moderate size, laterally compressed, and provided at apex with a 

 slightly curved finger. Supra-anal plate quadrate on basal half, 

 reduced to one-half the width and spatulate on apical half, slightly 

 sulcate at middle throughout, on the basal half provided with two 

 black longitudinal carinae and two tubercles of the same color. 

 Prosternal spine strongly hirsute, subcylindrical, quite long, and 

 strongly directed to the rear.

Habitat. — The material comprising this species comes from Cha- 

 pada, near Cuyaba, Matto Grosso, Brazil. The various specimens 

 were collected by H. H. Smith, during the months of July, August, 

 and September. The types are deposited in the Carnegie Museum. 



109. Leptysma grossa sp. nov. 

 Quite large (50 mm. in length) and with an unusually large head 

 and wide ensiform antennae. Tegmina long, narrow, and very 

 acuminate; the hind wings apparently wanting (at least this is true 

 of the single 9 specimen at hand). Sides of head, lower edges of 

 pronotum and pleura, provided with a rather conspicuous pale band, 

 which extends from the lower anterior edge of each eye to the insertion 

 of the hind femora. Face and pectus somewhat hirsute.
