Characters. — Face smooth. Palpus with second joint long, strong, subascending, clothed 
with long hair-scales beneath and rough-scaled above, third joint porrect or slightly deflexed, smooth- 
scaled, rather slender, in c short to moderate, in Q moderate to long (Fig. 9). Tongue present. 
Antenna rather short to moderate, in cf bipec- 
tinate to about two-thirds, with long branches,

ore lum in c rather short, from before well-marked 
basal expansion, in Q vestigial, often entirely wanting. Forewing with costa gently arched, apex 
squared or somewhat acute, termen entire, oblique, rather straight or gently curved, cell less than or 
fully one-half, DC incurved (usually continuously, very rarely with DC? separately curved, resulting in 
a form approaching that of the preceding genera), SC! usually from near end of cell or connate or very 
shortlv stalked, occasionally (frocumbaria, inductaría, biplaga, quadrinotata, integranola, atlenuata and 
perhaps a few others) well stalked, oftenest free, sometimes anastomosing with C, SC? usually arising 
before SC? (after it in biblaga, quadrinolata, integranota, attenuata, variable 1n frocumbaria), R! usually 
stalked with SC??, sometimes connate or separate, M! usually separate, sometimes connate or stalked ; 
hindwing with apex moderate (pronounced in feuera), termen. smooth or faintly waved, usually well 
rounded, sometimes straighter, tornus distinct (in fzcfipennis and its nearest allies slightly produced), 
cell less than or fully one-half, DC somewhat curved, typically becoming strongly oblique (DC? some- 
times separately curved, in subAyalina indeed almost angled), C shortly approximated to cell near base, 
rapidly diverging, SC? stalked, R? variable in position, tvpically from much above middle, M! verv 
variable, typically connate, approximated or very shortly stalked, sometimes (?nductaria, mariae, 
albicatena, and probably a.few others) longer stalked, occasionally (sub/rvalzna, tenera) widely separate at 
origin. c genitalia with uncus bifid, with pointed socii, enathos with arms not united (absent in Pustu- 
lataj, harpe sometimes dentate on inner margin, vinculum square (in iuductaria rounded), strongly 
emarginate at the base. penis long and slender (fustulata, inductarta, mariae and. integranota ceenitalia

Ecc — Very flat, a short rounded oval with micropylar end truncate, both sides deeply 
depressed, surface covered with a delicate, but very much raised, cell net-work (Bacot, Emf. Rec.

Lanva, — Exceedingly rugose, the skin shagreened or spicular, in first stadium an enormously 
developed lateral flange, specially developed processes on this flange (subdorsal on abdominal
