species and Forms o/GcometiIda3. 309 



Hind ^ving slightly narrower tlian in urcearia^ termen 

 similarly crenulate ; DC'^ ueak^ AP from close to li^ but not 

 quite connate ; discal ring larger than on fore wing, 

 markings otherwise almost the same, the subterminals not 

 quite obsolete in cellules 6 and 3. 



Underside more whitish, especially the distal and posterior 

 parts of fore wing and the whole of hind wing. Fore wing 

 with the cell-mark more oval and thicker-edged than above, 

 the markings beyond suggested, though very shadowy. 

 Hind wings with the markings nearly obsolete, the cell-mark, 

 postmedian, and terminal least so. 



E. Peru: Chanchamayo, 1000 m., October-November 

 190J. Type in coll. L. B. Front. 



Except in the shape — which gives more of the aspect of 

 some of the Indo-Australian species — very similar to urcearia, 

 Guen., though with more disparity between the sizes of the 

 discal rings and with no appreciable enlargement of the 

 subterminal dots between the radials. From stigmatilinea, 

 Front (Nov. Zool. xxvii. p. 278), it differs in the absence of 

 the hair-pencil, in the venation of the hind wing, weaker 

 irroration and markings, and rounder cell-rings. 



Subfam. Lab^entiin^. 

 6. Triphosa umbrifacta^ sp. n. 



S .—38 mm. 



Face with rather long pointed cone of scales. Palpus 

 elongate (2 J), rather heavily scaled, third joint distinct. 

 Antenna with very short ciliation. Abdomen relatively 

 rather short. Head and body concolorous with wings. 



Fore tvings shouldered at base, here swollen, beneath with 

 a membranous plate overhanging an ample cavity and partly 

 covered by longish hair from base, the retinaculum attached 

 to the plate (section Strepsizuga, Warr.) ; apex scarcely so 

 acute as in aberrans, Warr.^ and gavara, Druce, termen rather 

 more curved, slightly waved, but not crenulate ; blend of 

 colours nearly as in those species (ochreous-brown marked 

 with red-brown and irregularly clouded in distal half with 

 black -brown) ; basal patch rather smaller, ill-defined, 

 bordered by a curved line which runs obliquely to hind 

 margin close to base ; a pair of moderately distinct lines 

 midway between this and the central band, mostly parallel 

 with termen, straightish ; a slightly paler, feebly bisected 

 area between these and central band; central band of medium 

 width, scarcely darkened (slightly clouded with red-brown); 

 antemedian line partly blackened; about vertical from costa.
