MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 29 



nence at 1/3 of ^ving, running to upper edge of cell; continued in cell 

 by an ill defined roundish spot, below cell, by a cloudy piu"ple trans- 

 verse suffused patch; costal patch represented by a narrow marginal 

 elongate-suboval streak from before 1/2 to well below apex; less than 

 apical foui'th of wing suffused uith deep ferruginous purple with 

 anthracite gloss and wdth some four almost continuous, little outwards- 

 oblique parallel lines, first and second to anterior edge of apical 

 suffusion, third to termen above tornus, last to middle of termen; 

 ultimate of these lines dilated below costa so as to form a quadrate 

 spot before apex; apex with a dark ferruginous spot. Cilia deep 

 ferruginous piu-ple with anthracite gloss, opposite tornus cilia pale 

 ochreous. 



Hind wing rather thinly scaled; orange bronze, becoming deep 

 orange towards apex, dorsal portion as far as cell and vein 2 suffused 

 -with bronze fuscous, with darker veins. Cilia bronze purplish with 

 a narrow white basal line, towards tornus gradually tiu-ning fuscous. 



Female genitalia: Sterigma Httle modified, ostium, a simple broad 

 funnel, httle sclerotized. Ductus bursae very long, coiled. Cestum 

 narrow, along less than lower half of ductus, in two coils. Signum 

 with a slender capitulum and a slender long dagger. 



Material examined: Luzon, Mountain Province, Baguio, 7. V. 1945 

 (J. G. Franclemont) , 1 9, holotype, genit. slide 5089 (GUI); same 

 locahty 5000 ft. (Clagg), 1 9, paratype (BM). Mindanao, Davao 

 Prov., Mt. Mayo (Mati), 4000-5000 ft., 26-30.1.1931 (Clagg), 1 9, 

 paratype, genit. slide 5705 (CMP). "Philippines, Luzon, Baguio, 

 8.VI.1928" (W. Parsons), 1 9, paratype (Genova M). 



Nearest to Archips machlopis (Meyrick) from Java, having in com- 

 mon the peculiar shape of the fore wings; but differing by the color 

 of the hindwing which is deeper orange without the pale costa and, 

 especially, with normal costal cUia, not modified so as to form a thick 

 dark brushlike patch as in machlopis. The ostium bm^sae is also 

 quite different in machlopis, w^hUe the signum differs to a lesser degree 

 I expect the unknown male to be of the machlopis appearance.
