MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 193 



vertical to vein 2, thence horizontal to vein Ic, thence broadly promi- 

 nent and rounded, to vein la and along this vein to base. 



Male genitalia: Tegiimen moderate, ovoid, peduncle broad; uncus, 

 a long slender hook, with a dilated base which is membranous ventrally. 

 Vinculum rather narrow, V-shaped, saccus strong, clavate-truncate. 

 Valva elongate, sclerotized, strongly concave longitudinally, sacculus 

 forming a large and flat fold ^^^th a rounded top, covered with short 

 bristles. Costal half of valva well defined, costa sinuate at base, 

 cucullus rigid and sclerotized, forming a pointed blade, with a patch 

 of very long bristles in disc; there is a third flattened and rounded cusp 

 below the apical one, supporting a transverse tumescence with dense 

 long bristles. Anellus erected-quadrate, with httle diverging obtuse 

 and moderate aneUus lobes. Aedeagus moderate, gTadually slightly 

 attenuated, rather straight, basal fourth bent down. Cornuti, 

 numerous small spines. Coremata, two long and slender extensible 

 hair-pencils in sheaths. 



Material examined: Luzon, Los Banos (P. I. Baker), 1 cf , holotype, 

 genit. slide 5109 (USNM). 



Apparently closely allied to ^'Callartona purpurascens" Hampson 

 from Burma, differing in minor size of yellow markmgs, especially 

 in the hindwing, where the central spot is less extended in that species.
