sinuate latcratl of the rounded anjjle; median carina subobsolete, well indi- 

 cated at cephalic margin; no lateral carinae, the disk broadly rounding into 

 the lateral lobes; transverse sulci well marked, the caudal one deeplj' impressed, 

 metazona one-half as long as the prozona: lateral lobes with the dorsal length 

 slightly greater than the maximum depth of the same; cephalic margin mod- 

 erately oblique, faintlj' sigmoid: ventro-cephalic angle rotundato-rectangulate; 

 ventral margin with cephalic half strongly arcuato-emarginate, declivent ceph- 

 alad, nearly straight; ventro-caudal angle obtusely rounded; caudal margin of 

 lobes nearly vertical, straight; surface of lateral lobes bearing on ventral half 

 two callose areas, one semi-elliptical and cephalad of the other, which is roughly 

 circular. Tegmina slightly more than twice as long as the disk of the pro- 

 notum, acuminate, the venation finely and regularly patterned, the anal area 

 appearing cribroso-punctate: costal margin with a distinct but not very high 

 lobe at distal third, thence distad the same margin is straight, the tegmen 

 narrowing to the narrowly rounded apex. Wings reaching to the extremities 

 of the tegmina. Prosternal spine erect, acute, faintly recurved cephalad at 

 the apex: interspace between the mesosternal lobes verj' faintly transverse, 

 slightly narrower than one of the lobes: metasternal lobes subattingent caudad: 

 metapleura with a nearly circular callose area proximad, similar in character 

 to those on the lateral lobes. Abdomen moderately compressed, carinate dor- 

 sad: supra-anal plate slightly elongate trigonal, carinate and tectate distad, 

 with a distinct medio-longitudinal impressed area proximad: cerci short, 

 conical: ovipositor jaws slightly compressed, dorso-external margins of the 

 dorsal valves crenulate, apices moderate^ curved. Cephalic and median limbs 

 rather short. Caudal femora in length subequal to that of the pronotum and 

 tegmina together, surpassing the apex of the abdomen by less than the length 

 (cephalo-caudad) of the head, in form moderately robust, the greatest depth 

 contained about three and one-half times in the greatest length of the same; 

 dorsal carina rather finely serrulate, the distal extremity of the same with a 

 small blunt tooth, external paginae regularly sculptured, apex of genicular 

 lobes rounded acute-angulate: caudal tibiae slightly shorter than the femora, 

 appreciably expanded distad, the lateral margins crenulato-carinate, most 

 apparent distad, dorso-external margin armed with seven spines, the dorso- 

 internal one with eight spines: caudal metatarsi slightlj' shorter than the third 

 joint, second joint about five-eighths the length of the metatarsus. 



General dorsal color ecru-olive, this being limited laterad by a pair of dis- 

 tinct but not wide fuscous lines, which extend from the dorso-caudal portion 

 of the eyes across the pronotum, in the usual position of lateral carinae, and 

 margining on the sutural side the humeral trunk of the tegmina to the apex. 

 The head has the remainder of its surface ecru-olive to light yellowish olive, 

 with the strumose points more olive-ocher. Pronotum and pleura, mcso and 

 metasternum and caudal femora garnet brown, the callose areas on the lateral 

 lobes and plevu'a bright lemon yellow. Abdomen washed proximad with 

 garnet brown, bronze brown distad, the ovipositor jaws sulphine yellow etlged 

 with l)Iackish. Eyes olive-citrine with traces of fuscous; antennae dark russian 

 green i)roximad, becoming blackish mesad and distad. Tegmina with marginal 

 field t)ister, costal margin from the lobe distad broadly edged with fuscous. 

 Caudal femora with genicular extremity dark russian green, the arches washed
