Size small; form elliptical. Head with the greatest depth sUghtly greater 

 than the greatest width across the eyes; occipital outline strongly arcuate, 

 the width between the eyes one and one-third times the depth of one of the 

 eyes; face with the width between the antennal scrobes about three-fifths 

 that between the eyes; eyes hardly projecting, in basal outline strongly reni- 

 form; antennae at least a third again as long as the head, pronotum and closed 

 tegmina together. Pronotum trapezoid in general form, the cephaUc margin 

 narrow, subtruncate, cephalo-lateral angles broadly rounded, lateral margins 

 moderately arcuate, caudo-lateral angles rotundato-rectangulate, caudal mar- 

 gin subtruncate; lateral sections rather strongly defiexed, disk subdeplanate, a 

 subarcuate impressed area bounding the dark bars laterad. Tegmina about 

 three times as long as the pronotum, lanceolate, the greatest width (mesad) 

 almost equal to the greatest length of the pronotum; costal margin moderately 

 arcuate, sutural margin straight, weakly arcuate distad, apex narrowly I'ounded; 

 marginal field rather narrow, translucent, reaching almost to the middle of 

 the tegmen, discoidal and anal fields opaque; mediastine vein faintly bent 

 mesad; costal veins ten in number, very faintly clavate, oblique; discoidal 

 vein straight, discoidal rami three in number (costal one also bifurcate), longi- 

 tudinal; ulnar vein simple; anal vein reaching sutural margin slightly proximad 

 of proximal third; anal field acute pyriform. Wing with the costal margin 

 sinuate; costal veins eight in number, distinctly clavate distad, oblique; 

 humeral vein short, connecting with the four proximal costal veins, irregular; 

 discoidal vein reaching the proximo-costal angle of the appendicular field; 

 medio-discoidal area over three times as broad as the medio-ulnar area, with 

 three transverse nervures which form two quadrate areas mesad; ulnar vein 

 bifurcate at distal third, the cephalic ramus meeting the distal margin of the 

 discoidal field near the discoidal vein; appendicular field ample, in length 

 about one-half that of the remaining section of the wing, semielliptical, the 

 greatest proximal width somewhat greater than the length of the field. Abdo- 

 men of type missing. Cephalic femora with the ventro-cephalic margin bear- 

 ing a pair of spines at the proximal third and a distal pair, the former subequal, 

 the latter very unequal in length (distal longer), intervening section of the 

 margin closely haired. Median femora with three long spines on proximal 

 half of the ventro-cephalic margin, a single one distad, a long genicular spine 

 present, ventro-caudal margin with spaced spiniform bristles. Caudal femora 

 with three spines on the ventro-cephalic margin, one being distal, genicular 

 spine very long, ventro-caudal margin with spaced spiniform bristles; caudal 

 tarsi three-fourths the length of the caudal tibiae, metatarsus but slightly 

 longer than the remaining tarsal joints, a minute arolium present. 



General color light buff, becoming warm buff on the median section of the 

 pronotum, a pair of gently diverging bars on the pronotum and the greater 

 portion of the tegmina prout's brown, clearer and more translucent and weak- 

 ening in intensity distad on the tegmina. Head entirely prout's brown with 

 the buccal region whitish, the occipital region lighter than the face with three 

 spots of the general color transvcrsclj^ disposed; antennae prout's brown, 

 weaker distad, segments narrowly annulate distad with the general color. 

 Pronotum with the lateral sections subhyaline, the dark bars with their exter- 

 nal border bisinuate, the enclosed median pale area narrowly flask-shaped,
