Hiudmargins of both wings bluntly lieiit at veins 3 and 0, the projection at 

 vein 3 in the hindwings forming a slight tooth.

Forewings : fuscous grey, speckled with dark atoms ; the median area darker, 

 and towards its edges becoming dark brown ; the inner edge of this area convex 

 outwards from one-fonrth of costa to median vein, then forming a deep nearly 

 semicircular sinus basewards between median and submedian, followed by a narrow 

 blnnt projection below the submedian ; its outer edge from quite three-fourths of 

 costa, more or less parallel to hindmargin, forms a shallow sinus inwards between 

 vein 4 and the submedian fold, and below the submedian vein curves suddenly 

 inwards towards the inner edge ; discal mark consisting of two round black spots, 

 one above the other ; below the subcostal vein the dark central area is iuterrnjited 

 by a broad straw-coloured streak reaching from edge to edge, vein being marked 

 across it in rufous ; the outer edge is tinely margined with paler and succeeded by 

 a brown shade ; a slight dark submarginal shade ; two black submarginal dots 

 below apex ; fringe concolorous. 



Hiii(lu'inys : jiale grey, tinged with rufous, and dusted with fuscous ; a dark 

 brown, externally pale-edged, nearly straight postmedian line ; cell-spot obscurely 

 darker ; a single black and white marginal dot between veins 6 and 7. 



Underside of both wings rufous grey along costal third, more whitish below, 

 both areas alike thickly freckled with fuscous ; exterior line dark in both wings ; 

 cell-spot of forewings dull whitish, elongate ; in hindwings black and distinct ; 

 the marginal dots distinct in both wings. Head, thorax, and abdomen brownish 

 grey ; face, pectus, and thorax very hairy ; the patagia long. 



Expanse of wings : 38 mm. 



One (J from Marca, Peru 3000 ft., De('ember 1809, wet season (Simons). 



The hindmargin of both wings cnrved and crenulate, but without teeth. Owing 

 to the pale subcostal central streak this insect bears a superficial resemblance to 

 A. habenaria Guen, 



136. Prochoerodes cristata sp. nov. 



Forewings : reddish fawn-colour, with darker, somewhat olive fawn-coloured 

 striae and sufl'usion ; first line very indistinct, pale lilac, strongly excnrved above 

 the median vein and curved inwards below it, to inner margin at one-third, followed 

 immediately by a deeper tinged cloud ; outer line double, purplish with a lilac 

 centre, irregularly bent from vein to vein, from middle of inner margin to costa 

 shortly before apex, preceded by an iron-grey shade, and followed by an olive fawn- 

 coloured suffusion, which is strongest below apex and at inner margin, and throws 

 off an angulated cloud from middle to anal angle; fringe dark fawn; cell-spot large, 

 round, formed of raised black scales. 



Hindwings : without first line ; the double line central, touching the black 

 cell-spot ; an irregular jagged-edged olive-fawn-colour submarginal shade. 



Underside duller and plainer ; the cell-spots only marked. Face, palpi, and
