toothed, on each side just in advance of both the second and third 

 sulci prominently so by a single tooth much longer and heavier than 

 the others; the front margin also somewhat angulate and less promi- 

 nently studded with tubercles than the hind margin. Tegmina 

 short, broad, their apex rounded, reaching just beyond the hind margin 

 of the third abdominal segment, the costal edge lobate. Abdomen 

 compressed, strongly carinate above, rapidly tapering, the last ventral 

 segment pyramidal, acuminate; the supra-anal plate tectate, elongate- 

 triangular, rather deeply sulcate at middle on basal half. Anal cerci 

 short, slender, pointed. Prosternal spine pyramidal, rather slender; 

 meso- and meta-sternal lobes widely separated, the space about equal 

 to the width of the lobes themselves. Hind femora robust, slightly 

 surpassing the apex of the abdomen; hind tibiae nine-spined on outer 

 margin, the inner spines also nine in number, slightly curved, and a 

 very little larger than the external ones. 



General color above brunneo-fuscous, varied on the disk and sides 

 of pronotum and dorsal portion of head and abdomen With streaks 

 and patches of testaceous and piceous. Front between the anterior 

 edges of the eyes and cheeks dark ochraceous, the posterior lower 

 cheeks also of a similar shade, but fading into the darker anterior 

 edges and occiput. Legs and lower portion of body testaceous mottled 

 and Ilecked with cinereo-fuscous. Tegmina dark brown, conspicuously 

 and moderately widely bordered with dirty yellow or testaceous. 

 Inner spines of hind tibiae black, the outer ones, together with the 

 tibiae, themselves pallid. Antennae brownish testaceous basally, in- 

 fuscated apically. Eyes mahogany-brown. 



Length of body, cf, 30 mm., of pronotum, 1 1.5 mm., of tegmina, 8.; 5
