of one of the eyes, width of the interantennal protuberance hardly 

 more than one-half that of the interocular space: when seen from 

 the dorsum the eyes are moderately prominent, when seen in lateral 

 view they are sub-reniform ovoid: antennsje with the proximal joint 

 broad, subdepressed, the internal margin roundly enlarged; remainder 

 of antennae incomplete: palpi slender, elongate, third joint faintly 

 longer than the fifth and distinctly longer than the fourth joint; 

 fifth joint trumpet-shaped, its length about two and one-half times 

 the distal width, distal truncation faintly oblique. Pronotum 

 slightly longitudinal when seen from the dorsum, regularly rounding 

 transversely, when seen from the dorsum slightly expanding caudad; 

 cephalic margin of the dorsum truncate mesad, caudal margin 

 moderately arcuate, these margins cingulate; dorsum with the 

 medio-longitudinal sulcus indicated on the cephalic two-thirds, 

 very deeply so in the median region, a transverse sulcus weakly 

 indicated mesad: lateral lobes longitudinal, with a distinct caudo- 

 ventral trend; cephalic margin and ventro-cephalic angle regularly 

 and broadly rounded, ventro-caudal angle rounded rectangulate, 

 caudal margin slightly oblique, straight, the vicinity of the ventro- 

 caudal angle strongly impressed. Tegmina slightly surpassing the 

 apex of the abdomen, the closed pair cylindrical when seen from the 

 dorsum, the outline of the dorsal field narrowing in the distal fifth ; 

 venation simple, prominent, transverse nervures regularly placed, 

 separating areas which are regularly oblong: lateral field with the 

 discoidal vein straight, regularly but weakly diverging from the 

 humeral vein, incomplete veins costad of the mediastine vein two 

 in number. Wings fully developed, caudate, projecting distad of the 

 tegmina a distance slightly greater than the length of the head and 

 pronotum combined. Ovipositor moderately elongate, relatively 

 slender, very faintly arcuate proximad, more strongly so distad; 

 distal extremity moderately acute, weakly crenulate on the dorsal 

 margin, almost to the weak swelling, which is situated at the distal 

 three-fifths: subgenital plate slightly broader than long, the apex 

 briefly fissate, rounding narrowly into the margins of the plate. 

 Cephalic and median limbs elongate, straight, moderately tapering: 

 cephalic femora subequal to the combined leng^th of the head and 

 pronotum; cephalic tibiae subequal to the femora in length, the 

 distal half quite slender, both faces of the tibiae with elongate reni- 

 form tympana, those of the two faces subequal in size: median 

 femora faintly shorter than the cephalic ones; tibiae subequal in 

 length to the cephalic tibiae and distinctly surpassing the median
