The species seems to share the bark-living habits with several 

 South Asiatic species of the genus Limnaecia. It may be redescribed 

 after the Philippine material as follows. 



Male and female, 20 mm. Head and palpus white, palpus with 

 basal segment, and lower third of median, black; terminal segment with 

 a small blackish basal ring and blackish tip. Thorax white, with a 

 curved median transverse series of (apparently) four black dots 

 (damaged). Abdomen sordid white, tergites with brassy-golden 

 bristled areas, venter yellowish. 



Forewing ovate-lanceolate, moderately broad. Snow white, mark- 

 ings black and well defined or grey with a ferruginous tinge, and 

 slightly suffused. Basal fourth of costa or less, narrowly black. A 

 black spot on base of costa, another smaller one below and beyond it; 

 a separate, oval larger spot beyond the first pair below costa, followed 

 by two dots, all in an oblique series; a series of four dots, first elongate 

 below and before 1/3 of costa, second slightly before it, in cell, third 

 elongate, rather beyond and sHghtly below the second, also in ceU, 

 and fourth in fold at middle of wing length; a rounded conspicuous dot 

 on end of cell; some five or six elongate somewhat suffused dots in a 

 submarginal strongly curved row, arranged between ends of veins, 

 from 2/3 of costa, to below middle of termen; some seven or eight 

 black spots or bars from costa before apex along termen to tornus and 

 a small dot on end of dorsum. CiUa snow white, with small black 

 subbasal dots opposite veins. 



Hindwdng pale grey, tinged fuscous towards apex, throughout with, a 

 strong sUvery-metaUic gloss. Cilia whitish fuscous grey, less glossy. 



Male genitalia of the closely allied S. microsperma (Diakonoff) have 

 been described at some length (Diakonoff, 1954, p. 88). Little can be 

 added, except that my figure 631 represents the total view of the 

 genitalia not in ventral aspect, as is stated in the caption and in the 

 text, but in dorsal aspect; the remainder of the description is correct; 

 figure 632 represents not the valva, as stated, but a lateral aspect 

 of the right halves of the eighth sternite (below) and tergite (above it). 

 At the time I noticed the similarity with the Cosmoptergid type of the 

 genitalia and was in favor of separating the Scaesophidae from the 

 Oecophoridae, not knowing yet that Scaeosopha itself was a Cosmop- 

 terigid.
