tion is in a vertical position, dorsum of the fastigiuni broadly but not 

 very deeply sulcate; facial fastigium acute, distinctly separated from 

 the fastigium of the vertex; eyes subglobose, prominent; antennae 

 about three times the length of the body (exclusive of the ovipositor), 

 filiform, proximal joint rather large. Pronotum with the disk flattened 

 only in the caudal section, the cephalic and median sections being 

 rounded into the lateral lobes with a scarcely perceptible median angle, 

 the greatest caudal width being continued about once and a half in the 

 length, cephalic margin of the disk and lateral lobes truncate, caudal 

 margin of the disk arcuate; lateral lobes about as long as deep, humeral 

 sinus broad, shallow, the remainder of the caudal margin gently arcuate, 

 cephalic section of the ventral margin sinuate with the ventro- 

 cephalic angle obtuse. Tegmina about once and a half the length of the 

 body (exclusive of the ovipositor), extending beyond the caudal 

 femora by about the length of the pronotum, lanceolate, the greatest 

 width contained nearly four and a half times in the length, costal 

 margin very slightly arcuate, sutural margin straight 

 in the distal three-fourths, apex rounded; median 

 vein diverging two-fifths the length from the base 

 and furcate with the rami reaching the sutural margin. 

 Wings extending beyond the tegmina a distance 

 nearly equal to the length of the pronotum. Supra- 

 anal plate trigonal, acute; ovipositor about two-fifths 

 the length of the tegmina and slightly more than half 

 that of the caudal femora, moderately arcuate in the 



distal two-thirds, straight in the proximal third, the ,.. ,,

 dorsal margin very slightly crenulate, ventral margin (X 4.) 

 distinctly crenulate; subgenital plate short, slightly 

 inflated, tlie margin with a broad shallow triangular'emargination. 

 Cephalic femora about equal to the pronotum in length, armed on the 

 distal section of the ventro-cephalic margin with three spines; median 

 femora slightly longer than the head and pronotum together, armed 

 on the ventro-cephalic margin wdth three spines. Caudal femora equal 

 to the body in length, considerably inflated distad, ventral margins 

 armed with one or two spines near the apex; tibiae exceeding the 

 femora by near the length of the pronotum.
