tapering distad: caudal tibiae but faintly shorter than the femora; 

 dorsal margins armed with six external major spines and seven 

 internal ones, the intercalated spinulations numbering 3-2-2-2-0 on 

 the external, and 3-2-1-1-1-0 on the internal margin; distal spurs 

 of the external side small, the internal side having the dorsal distal 

 spur slightly less than twice as long as the ventral pne: caudal meta- 

 tarsi very short, the dorsal surface with two external and one in- 

 ternal spinulations, distal spurs of both sides slightly surpassing the 

 second tarsal joint. 



General coloration pale buckthorn-brown, the head inclining to- 

 ward dresden-brown, the venter of the abdomen ochraceous-tawny. 

 Ocellar region outlined dorsad with fuscous, a V-shaped patch of the 

 same on the occiput; eyes auburn with a median and a dorsal thread 

 of fuscous. Pronotum with a fuscous medio-longitudinal line which 

 is almost completely divided by a thread of the general color, points 

 of fuscous regularly disposed along the cephalic and caudal margins 

 of the disk and along the lateral border of the same, a very faint 

 wash of russet suggesting a post-ocular bar. Tegmina with a moder- 

 ately broad bar embracing the humeral vein, fuscous, bordered 

 suturad by the pale ochraceous-buff pencilling of the median vein. 

 Abdomen with the dorsum shining blackish-fuscous. Caudal tibiae 

 dorsad weakly washed with mummy-brown. Ovipositor finely 

 lineate on the external surface with blackish-fuscous, the valves 

 chestnut with blackish-fuscous teeth. 



Length of body, 16.5 mm.; length of pronotum, 2.7; greatest (cau- 

 dal) width of pronotum disk, 3; length of tegmen 13.8; greatest 

 width of dorsal field of tegmen, 2.3; length of caudal femur, 12.3; 

 length of ovipositor, 18.5. 



The type of this very striking and peculiar species is unique.
