deeper than long, considerably impressed mesad, ventro-caudal angle 

 rounded. Tegmina rather broad, the greatest width contained 

 slightly more than four times in the length ; costal lobe very slight and 

 low, sutiu-al margin straight, apex obliquely truncate toward the 

 sutural margin, the distal third of the costal margin arcuate, making 

 the immediate apex rounded rectangulate; intercalary vein distinct, 

 intermediate in position proximad, close to the median vein distad. 

 Wings moderately falcate, broad, the breadth being contained about 

 once and a half in the length; humeral field with the apex rounded 

 acute-angulate ; axillary field with the margin very slightly arcuate 

 and not lobate, being no more prominent than the next area in the 

 radiate field ; posterior axillary vein with its ramus paralleling closely 

 the anterior axillary vein for a considerable distance, but not coalescing 

 with it; radiate veins moderately thickened. Caudal femora rather 

 slender, the ventral carina distinctly but slightly produced arcuate; 

 caudal tibiae with nine spines on the lateral margins. 



General color ecru drab, sprinkled, spotted and blotched with drab; 

 eyes burnt umber; antennse of the paler color annulate with bistre; 

 dorsum of the pronotum and the lateral lobes marked with the darker 

 color. Tegmina with traces of three bands of quadrate and ocellate 

 spots, these spots being almost wholly formed by the infuscation 

 veins and cross veins, the bands being proximad, proximo-mesad and 

 disto-mesad, while the distal third is supplied with scattered quadrate 

 ocelli of the darker color. Wings with the transverse band very weak 

 and almost severed, being chiefly an infuscation of veins and without 

 definite limits, extending caudo-mesad and with a broad, moderately 

 distinct stigma which extends half way to the base, the color of the band 

 and stigma being drab ; distal portion hyaline except for inf uscate veins, 

 proximal portion citron yellow. Cephalic and median limbs of the 

 general colors annulate ; caudal femora with a pale pregenicular annulus, 

 and with traces of two transverse bars which are more distinct dorsad ; 

 caudal tibiae pale, infuscate proximad and distad, the spines touched 

 apically with blackish.
