 elongate-triangular, resembling that of stuarti (PI. XLVII. f. 3), conical distally, 

 apex obtnse. Peuis-sheath nearly as in ericea (PI. LIV. f. 5), but whip with more 

 tnliercles. Armature of penis-funnel (PI. LIII. f. 48): only one process on each 

 side, this process heavily dentate at the outer and distal edges ; below the funnel 

 (in front of it in figure) there is a deeply sinuate ridge ; the membrane surrounding 

 the armature laterally and dorsally as a kind of mantle neither spinulosc nor hairy.

 *Perlgo7iia niclffaiis Boisduval, ?.'■. 



c? ? . Easily distinguishable from the other species of southern Brazil by the 

 reddish colour of the hindwing and the brown abdominal area which extends to the 

 base. On the underside of the forewing there is a large postdiscal patch between 

 costal margin and R- of an ochraceous clay colour, including proximally a sharply 

 marked brown line, besides traces of another line ; this patch is sejjarated from a 

 posterior discal patch of the same colour ; black submarginal line bordering the 



greyish brown marginal band straight from 11^ to hinder margin. Hindwing 



dirty rufous-oehraceous, except margins, three discal lines and a stigma.

Umierside. of wings and abdomen deeper tawny and chestnut-tawny, the greyish 

 black colour more extended ; the postdiscal postcostal patch of forewing chestnut- 

 tawny, much reduced, reaching SC< only distally, 1 mm. or less wide between SC^ 

 and SC', the posterior discal patch also reduced, the brown lunulated lines within it 

 heavy ; greyish brown borders of hindwing broader than in the preceding, the 

 chestnut-tawny area consequently more reduced, not reaching distally to C, as it does 

 in the Brazilian fiirm.
