The present individual is compared with specimens of S. torrida 

 Stal under that species. It differs similarly from S. rugosa (Lin- 

 naeus), except that the elevation of the pronotal disk is fully as 

 prominent in its caudal portion.

The pale face, truncate tegmina and black spines of the cephalic 

 femora distinguish this insect. In the present specimen the head 

 and thorax ventrad, limbs and even the first antennal joints are 

 thickly supplied with long silky hairs, which are strikingly evident. 

 The general coloration is grayish brown, the tegmina irregularly 

 mottled with pale greenish and rusty brown. The costal margin 

 of the sinistral tegmen has three, that of the dextral tegmen six, 

 moderately large, rounded triangular projections. 



The previously unknown male has the supra-anal plate small, 

 produced and shield-shaped. The cercus is nearly semicircular, 

 with apex minutely toothed. The subgenital plate is broad and 

 shining black proximad with a broad subchitinous pale medio- 

 longitudinal sulcus, then suddenly narrowed, the slender distal 

 portion pale, short, with apex briefly forked and bearing moderately 

 heavy styles, which curve inward distad.
