354 NEW TROPICAL AMERICAN ORTHOPTERA 



Size small : form and surface as usual in this aberrant genus. 



Head moderately transverse when seen from the dorsum, the greatest width 

 across the eyes much greater than the medio-longitudinal length of the head, 

 greatest depth of head about one and one-third times the greatest width across 

 the eyes: occiput strongly declivent, weakly arcuate, outlined dorsad by a low, 

 rounded carina, which forms a nearly rectangulate border margining the eyes 

 and antennal scrobes dorsad, the two arms of the border joining at the inter- 

 fastigial suture; fastigium of the vertex rather low, but weakly elevated and 

 gently arcuate in profile, narrowing and compressed distad, a slight medio- 

 longitudinal sulcus indicated dorsad; fastigium of the face not in contact with 

 that of the vertex, broad, semi-globose, not elevated; face with surface moder- 

 ately cribroso-punctulate, genae smooth; palpi with fourth joint two-thirds as 

 long as third joint, distinctly sigmoid, weakly expanding distad, fifth joint 

 faintly longer than third and fourth joints combined, slender at base, moder- 

 ately thickened distad, slightly arcuate proximad, extremity rounded: eyes 

 rather prominent when seen from the dorsum, slightly flattened semi-globose; 

 basal outline of eye ovate, narrowed ventrad, depth of eye faintly greater than 

 that of the infra-ocular portion of the genae: antennae incomplete, beyond the 

 enlarged proximal and second joints filiform, brittle. 



Pronotum in general sellate, the dorsum deplanate, in profile the dorsum 

 of the pronotum is low cephalad, slightly ascending mesad and deplanate 

 caudad, lateral angles of same pronounced, lateral lobes vertical: dorsum of 

 pronotum with greatest caudal width contained one and one-third times in 

 the greatest length of the same, all margins of same cingulate, the surface 

 velutinous; cephalic margin of disk arcuato-subtruncate, caudal margin broadly 

 arcuate rotundate, lateral margins, though sinuous, diverging caudad, passing 

 without interruption into the caudal, and by a rounded angle into the cephalic, 

 margins, narrowly severed briefly caudad of the latero-cephalic angle ; surface 

 of the disk with a faint, imperfectly and incompletely indicated median sulcus, 

 a median V-shaped figure, which is more distinctly indicated than the median 

 sulcus, being placed distinctly cephalad of the longitudinal center of the disk : 

 lateral lobes appreciably longitudinal; greatest depth of the lobes slightly 

 caudad of the middle, the cephalic depth equal to three-fifths of the greatest 

 depth; cephalic margin arcuate-emarginate dorsad and straight mesad and 

 ventrad, ventro-cephalic angle narrowly rounded rectangulate, ventral margin 

 slightly oblique and weakly sinuate cephalad, broadly and evenly arcuate from 

 the middle of the ventral margin to the humeral sinus, the latter narrowly 

 rounded rectangulate; surface of the lateral lobes with a distinct impressed 

 area dorso-caudad. Tegmina of the character found in the other species of 

 the genus, with a proximo-costal and a medio-sutural desiccated area, and 

 scattered similar spots ; in length about one and two-thirds times as long as the 

 body with the ovipositor, in general form elongate elliptical-ovate, its greatest 

 width, which is at five-eighths the length from the base, contained slightly 

 more than two and one-half times in its greatest length : costal margin in proxi- 

 mal half oblique (to the tegminal axis), straight, this broadly rounding to the 

 distal section, which is oblique subtruncate toward the apex, gently rounding
