6 ? . Antenna thickest in basal half. First segment of tarsi shorter than 

 fihiiie. D' of hiudwing as long as, or somewhat shorter than, D'. Scaling of head 

 long, hanging over the eyes as a kind of e3e-lashes ; palpns also rongh-scaled. 

 Tibiae not spinose ; first segment of foretarsus externally with a number of spines 

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

 none obviously longer and stouter ; midtarsns with comb ; puhiUus 'and paromj- 

 chium 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 reseml)ling that of I'rotopnrce sexta, the side- 

 margins parallel, tnrned u]iwards and inwards jnst before end. Clasper elongate 

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

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

 triangnlar obtnse jjcnis-funuel beneath the penis-sheath ; the latter, as in Protopnrce 

 lustica and other species, with an apical, almost horizontal, tooth pointing dextro- 

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

 to distinct tnfts, reminding one of Macroglossiim. 



?. Vaginal plate proximally broadly ronnded, 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 granulose, rounded. — Food : Prinos, Ilex, 

 Comptonia, Asimia. 



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



Ilab. North America. 



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

 which resembles Protoparce ruMica in the colour of the wings, and several other 

 Protoparce in that of the body. It is more specialised than any species of Proto- 

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

 Protoparce in the possession of a pnlvillus.
