MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 25 



4 cf. Mindanao, Lanao, plains, Kolambugan, 30. V, 9 and 13. VI. 

 1914, 2 cf , 2 9, (A.E. Wileman); 11 c^, 2 9 (BM). Mindanao, VII- 

 VIII.1917 (Clagg), 1 cr', 1 9 (CMP). An interesting, large species; 

 the females are characteristic by strongly sinuate costa of the fore- 

 wings. 



The male has been described mider the name Cacoecia xantho- 

 chroma Wileman and Stringer. I studied the following paratypes 

 of that species: 1 cf, Mindanao, prov. Lanao, Kolambugan, sea 

 level, 30.V.1914, and 1 9, Luzon, prov. Benguet, Klondyke, 800 ft., 

 11. III. 19 12 (A.E. Wileman). 



The male may be redescribed as foUows. 



Forewing elongate, trimcate, moderately dilated, costa without 

 a costal fold, moderately cm-ved anteriorly, slightly cm'ved posteri- 

 orly, apex subrectangiJar, obtusely pointed, termen gently sinuate 

 above, moderately convex beneath, little oblique. W^hitish ochreous, 

 on costal half sometimes variably suffused with dark leaden grey. 

 Markings pm-ple or brown. Anterior third of costa more or less 

 suffused with brown and with a few small, transverse marks. Basal 

 patch indicated by a crescentic fasciate patch, from beyond base 

 of dorsimi, slightly inwards-oblique, to 1/4 of disc, end tm'ned up- 

 wards and obtusely pointed; and by a small round dot halfway betw^een 

 costal edge and above-mentioned mark, slightly before its point, 

 transverse fascia indicated by a wedge-shaped spot on 1/3 of costa, 

 an invert-pyriform spot below and beyond it, extending with a 

 narrowed point to lower angle of cell, and a faint grey quadrate 

 suffusion on 3/4 of dorsum with its concave anterior edge continued 

 by a line rising almost to middle of the anterior edge of pyriform 

 spot; costal patch mdicated by a purple streak along costa from 

 before its middle to before apex, and by a sinuate line from posterior 

 edge of that streak to 3/4 of termen; a dot in the extreme angle, 

 continued as a terminal line to middle of termen; posterior third 

 of wing more or less transversely strigulated with piu-ple. Often 

 the markings are reduced, but they are seldom as complete as de- 

 scribed above. 



Hindwings variably suffused with grey, dorsum paler. 



Females 25-31 mm. The markings are rather constant but 

 limited to the slender costal half of the transverse fascia, the narrowiy 

 fasciate costal patch and a less distinct sinuate preterminal line from 

 apex. The ground color may vary stronger: from whitish ochreous 

 to greyish ochreous, variably suffused with lilac grey. 



Male genitalia, Tegumen moderate, rather slender, almost twice 

 as high as broad. Gnathos, a slender hook, reaching 3/4 distance 

 towards transtilla. Socius parietal, several spread bristles. Uncus 

 rather short, top rounded TranstiUa very slender, strongly nar-
