Hedya (Hedya) atrifraga, new species 



Figures 67, 524 



Male, 14.5 mm. Head fuscous. Palpus sordid pale oclireous, 

 with an oblique supramedian and an apical dark fuscous band, 

 terminal segment dark fuscous. Antenna fuscous tawny, ciliations 

 under 1, white. Thorax dark fuscous grey, tegulae mixed with pale 

 and dark purple grey. Abdomen grey, venter and anal tuft pale grey. 



Forewing elongate-subtruncate, little dilated, costa curved along 

 anterior half, straight along posterior, apex moderately rounded, ter- 

 men almost straight, little oblique, rounded beneath. Light slatey 

 grey, \\'ith a strong lilac opalescence in certain lights, below costa 

 posteriorly suffused with light tawny orange. Markings orange 

 brown and dark fuscous, posteriorly edged and mLxed with pale tawny. 

 Costa with some seven pahs of white marks, separated by blackish. 

 Basal fourth of costa blackish, containing an oblique spot of ground 

 color beyond base; below this fourth of costa upper portion of disc 

 indistinctly suffused with dark fuscous, towards dorsum becoming an 

 ill-defined dotting; edge of this basal patch ill defined, probably 

 rounded; a blackish moderate transverse fascia, from middle of costa 

 to dorsum before middle, strongly angulate outwards on upper edge 

 of cell, thence straight and inwards-obUque; a dark oblique blotch 

 from below costa well before apex, terminating in middle of termen, 

 and emitting from its middle a branch to dorsum before tornus; apex 

 beyond this mark slatey white, with a dark brown marginal line and 

 a somewhat inwards-oblique subapical line. Cilia (rubbed) fuscous 

 grey. 



Hindwing and cilia rather dark grey. 



Male genitalia: Uncus moderately broad, with a V-shaped, bristled 

 surface ventrally (in front) . Gnathos semimembranous, rather folded 

 transversely, with two converging small folds along the upper edge 

 and sUghtly prominent ends of two larger folds laterally. Valva 

 moderately slender, cucullus not dilated throughout, gently curved, 

 with large but rather scattered bristles, slightly more condensed along 

 lower edge; Spci very dense, rounded, moderate, Spc2 moderate, much 

 smaller than Spci, closer to this than to base. 



Material examined: Mindanao, Zamboanga del Sur, 11 km NW of 

 Milbuk, 390 m, 5.VIII.1958 (H.E. Million), Icf, holotype, genit. 

 slide 5309 (BMH). The single specunen is rather damaged, but the 

 genitaha are sufficiently characteristic. An interesting form, being 

 the first tropical member of the subgenus Hedya which comes to my 

 notice.
