i ? . Antenna thickest in basal half. First segment of tarsi shorter tiian 

 tibiae. D' of hindwing as long as, or somewhat shorter than, D'. Scaling of head 

 long, hanging over the eyes as a kind of eye-lashes ; i»alpus also rongh-scaled. 

 Tibiae not spinose ; first segment of foretarsns externally with a number of sj)ines 

 at base besides the normal first row, all these spines of about the same length, 

 none obviously longer and stouter ; midtarsas with comb ; pultilliis 'and jmroiu/- 

 chiiim present. 



S. Tenth tergite prismatically compressed, under surface reduced almost to a 

 line, dilated ventrad before end, apex sharply hooked, the dilated part rough with 

 wrinkles and granules ; sternite resembling that of Frotoparce sexta, the .'iide- 

 margins parallel, turned ujiwards and inwards just before end. Clasper elongate 

 sole-shaped ; harpe triangular, produced into an obtuse ventro-distal process, 

 surface somewhat concave, with dispersed scales, edges not dentate. A short 

 triangular obtuse penis-funnel beneath the penis-sheath; the latter, as in Frotoparce 

 ruxtii-u and other species, with an a])ical, almost horizontal, tooth pointing dextro- 

 laterad and somewhat distad. Scales at lateral edge of seventh tergite prolonged 

 to distinct tufts, reminding one of Macroglossxm. 



?. Vaginal plate proximally broadly rounded, produced in front of the median, 

 transverse, vaginal cavity into a broad, irregularly notched ridge, which, in a 

 ventral view, covers the cavity entirely ; postvaginal portion of plate more or less 

 membranaceous, rounded, scaled (except in middle line). 



Larva with six distinct white and red oblique lateral bands, the band on 

 segment 5 not being well marked ; head grannlose, rounded. — Food : Frinos, Ilex, 

 Comptonia, Asimia. 



Pupa with free tongue-sheath, which is closely applied to the breast. 



Ilab. North America. 



The genus is closely related to Frotoparce. It contains only one species, 

 which resembles Frotoparce rustica in the colour of the wings, and several other 

 Frotoparce in that of the body. It is more specialised than any species of Froto- 

 parce in possessing eye-lashes, while it agrees with the more generalised species of 

 Frotoparce in the possession of a pulvillus.
