infuscated in the apex; termen twice excavate. Cilia light golden-ochreous, 
infuscated, except along their base, more so towards and in the apex. 
Tegumen strong, erect. Uncus bilobed, with the tops finely bristled. 
Socii absent. Gnathos, a strong pending plate, formed by triangular 
lateral sclerites and curved, spoon-like median projection. Valva with 
triangular base, strongly narrowed, cucullus hooked, bristly; sacculus 
moderate, ending in a curved, spoon-like process; a strong crochet in 
the disc of the valva towards the costa with a dilated base, edged below 
and followed by groups of bristles. Aedoeagus strong, triangularly dilated 
towards base, its top curved. Cornuti not perceptible. (Slide no. 1117 D, 
type.) 
Sigi Camp, 1500 m, February 18, 1939. One specimen. The genitalia 
approach those of Aristotelia (Ptocheuusa) inopella Zeller, from Europe,
