as a fine sul cation; surface with numerous scattered fine asperities; 

 transverse sulcus truncate mesad, arcuato-rectangulate laterad. 



Tegmina surpassing the apex of the abdomen, in shape ovoid, 

 one and four-fifths times as long as the pronotum, l)road, the great- 

 est width about two-fifths of the greatest length, marginal field 

 opaque, discoidal and anal fields translucent; costal margin strongly 

 and regularly arcuate, sutural margin largely straight, rounding 

 to the rotundato-rectangulate apex; marginal field forming about 

 one-third of the total tegminal width, oblique veins of the same 

 quite irregular and much forked and fused; discoidal sectors five 

 to six in number, oblique, equidistant, moderately sigmoid, trans- 

 verse nervures moderately regular, irregular false sectoi's present 

 toward the sutural margin; anal vein moderately arcuate, join- 

 ing the sutural margin slightlj^ proximad of the middle, anal field 

 wth axillary veins disposed similarly to the discoidal sectors; stigma 

 distinct, close to the humeral trunk proximad of the middle, longi- 

 tudinal, uncolored. Wings reaching to the tips of the tegmina, sul)- 

 hyaline translucent. Abdomen depressed, broad. 



Supra-anal plate produced mesad into a linguiform process which 

 is subequal to the proximal width of the plate; subgenital plate 

 strongly compresso -rostrate distad, this section deep. Cephalic 

 coxae faintly longer than the shaft of the pronotum, faintly arcuate 

 distad, dorsal margin biseriate denticulate, the larger series six in 

 number and recurved, the smaller ones minute and more numerous, 

 the numbers between the larger denticulations variable, ventral mar- 

 gin sparsely serrulato-denticulate, the external margin similar but 

 more closely armed, internal face with a few low tubercles parallel 

 to the dorsal margin; cephalic femora faintly shorter than the pro- 

 notum in length, greatest depth contained three and one -half times 

 in the greatest length, subcompressed, dorsal margin straight, ventro- 

 external margin with four large spines, slightly longer proximad, 

 lateral genicular lobe with a single rather short spine, ventro-internal 

 margin with thirteen spines which are biseriate in length, the for- 

 mulae (reading distad) being ilililililiil, discoidal spines four in 

 number; cephalic tibiae (exclusive of the apical claw) subequal 

 to one-half the femoral length, external margin armed with seven 

 spines increasing in length distad, a considerable unarmed diastema 

 present proximad, internal margin with eleven spines increasing in 

 length distad, apical claw quite long, gently arcuate; cephalic meta- 

 tarsi subequal to the remaining tarsal joints in length. Median 

 and caudal limlis elongate, tibial carinations weak.
