of transverse sulci, truncate in the male, or sub-truncate in the female, 

 both in front and behind; lateral lobes similar to those in Conocephaliis 

 nemoralis Scudder and C. propinquus Redtenbacher. Tegmina 

 broadly lobate in both sexes, scarcely reaching the hind margin of 

 the pronotum in the female, or the hind margin of the first abdominal 

 segment in the male. i\bdomen above glabrous, without a median 

 carina. Cerci of male straight, a little tapering and rather short, 

 the inner side without a tooth, but with the apex two-toothed, the 

 inner one of these a trifle the shorter, blunt, the outer one acuminate. 

 Subgenital plate rather broad, its apex bisinuate, the styles short 

 and blunt. Ovipositor very robust, broadly sickle-shaped, the apex 

 finely acuminate. Prosternum two-spined, mesosternum acutely 

 lobate, the metasternum triangulately lobate. Legs normal, the 

 "anterior and middle tibiae armed below with six pairs of spines, all the 

 femora below spineless, the genicular lobes of the hind pair provided 

 with a single blunt spine. Auditory openings of front tibiae linear. 



General color fusco-brunneous, paler beneath (obscure testaceous) ; 

 front, cheeks, sides of pronotum and legs, profusely flecked with round 

 ferruginous to piceous dots from the centers of which usually arise 

 short pallid hairs. Fastigium of the vertex above, occiput and disc 

 of the pronotum, together with a wide dorsal stripe on the abdomen, 

 piceous in the male, much paler in the female, bordered on each side 

 by a prominent testaceous line, the sides of pronotum above and 

 sides of abdominal segments on the basal two-thirds piceous. Basal 

 half of hind femora externally prominently fasciate longitudinally 

 with fuscous. 



Length of abdomen, cf, 9.2 mm., 9, 13 mm.; of pronotum, cf, 

 2.55 mm., 9 , 3-1 mm.; of tegmina, cf, 1.25 mm., 9 , i mm.; of hind
