Characters, — Build robust. Frons strongly protuberant (except in Piclaria and neonoma), densely 
scaled, but not tufted 1). Palpus moderate, second joint densely rough-scaled, third joint moderate to 
rather short, smoother scaled. Tongue developed, antenna somewhat variable in length, in gf usually 
bipectinate, with moderate to short branches, in Q usually nearly simple or weakly subserrate, 
rarely (luteipes, superans and. meonoma) shortly bipectinate. Pectus and femora densely hairy. Hindtibia 
with all spurs, in cf often with slight, but rarely (decorata, aficalts) with strong hair-pencil. Metathorax 
sometimes crested, but never with the highly-developed crest of Dindica. Abdomen with well-developed 
mediodorsal crests (small in Aaemataria and ornataria); Q abdomen typically very robust. Frenulum 
fully developed. Forewing usually broad, costa gently arched, apex moderate, termen somewhat curved, 
more or less oblique, usually more or less subcrenulate, cell nearly always less than one-half, 
DC incurved, SC! from cell, free 2), SC? stalked with SC?5, R! not stalked, M! not stalked; hindwing 
with apex rounded, termen waved or crenulate, sometimes rather irregular, tornal area sometimes 
produced, inner margin always long, cell usually short (one-third to two-fifths), DC usually with a trace 
of angulation at R?, but never of the extreme form of Pingasa, ZEolochroma, etc., C shortly approximated 
to cell in its second fourth, rapidly diverging, SC? nearly always separate (very shortly stalked in 
subornafa, and in the only known specimen of differeus), R? from somewhat above middle of cell, 
M! separate. cf genitalia with uncus bifurcate, gnathos pointed, with small scobinations, harpe 
emarginate at the apex, penis shuttle-shaped, pestillate, aedeeagus scobinated at the tip (vigens). 
Early stages scarcely known. 
1) Slightly tufted in Percomfíaria, which is probably sz generis. 
2) It is very remarkable that, notwithstanding the structural diversity within this genus, we have found absolutely no exception to this saving 
the unique type of ca/auxofs and a single example of oxzaaria, and in the latter SC! anastomes shortly on oze zizg only — an obvious sport.
