black apical blotch, traversed by a snbmarginal line of whitish spots : hindwing 

 grey-speckled, with traces of grey waved lines and a dark cell-spot. 



Head, thorax, and abdomen a mixture of black, white, and ochreous scales, 

 the abdomen dorsally spotted witii ochreous and with an ochreons band behind

1 ? from Tucuman, Argentina, May l'.)02 (Dinelli). 



The distribution of the ochreous tints is variable ; in the right wing extending 

 along the costa throughout, and in the left stopping at the central fascia; the ends 

 of veins 2, 3, 4 are also ochreous in the riglit wing, but olive-brown in the left. 



Lasiophaues gen. nov. 



A development of Per/.-owrt, parallel with ('V;v/w/7*c«wf/, but, whereas the latter 

 has a bed of rough hair on the underside of the forewings, the present genus has 

 the whole of the upperside of the hindwings, except towards apex, covered with 

 rough hairs, developed towards anal angle into curved wisp.s. Palpi shortly 

 rostriform ; antennae simply lamellate.

Foreicinc/ : ashy grey : the lines blackish ; a short line close to base and two 

 very fine ones in the baud beyond ; inner edge of central fascia marked by a 

 black line from one-third of costa to one-fourth of inner margin, bent below costa, 

 this edge followed by a broad grey baud with outer wavy edge ; outer edge of central 

 fascia from two-thirds of costa, oblique outwards with a slight bend at 6 to vein 4, 

 then hardly oblique to anal angle : from costa to median this edge is preceded by 

 blackish suffusion and two jiarallel dark lines, and edged with white ; below the 

 median the whole fascia is grey, with a pale central space and some whitish in cell ; 

 submarginal line fine, waved, white, preceded above middle by blackish oblong 

 streaks between the veins ; the veins themselves, vein 6 broadly, bright buff ; 

 vein 4 also narrowly bnft' from its origin at angle of cell ; marginal area grey ; an 

 interrupted dark marginal line ; fringe grey mottled with darker. 



lliudiriiig : wholly shaggy dark grey. 



Underside dark grey except along costa and across apex, where the ground-

 pale grey with darker strongly cnrveil transverse lines, of which the postmedian 

 is marked with blackish points on veins. 



Head, thorax, and abdomen grey ; the collar, shonlders, and jiatagia showing 

 paler.

The dark scales on the underside of forewing are rough and coarse over an 

 area corresponding to the roughened surface of the hindwing.
