MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 43 



by a pale fascia from 3/4 of costa to lower half of termen; this fascia 

 narrow above, abruptly extended along lower half, olive, narrowly 

 edged on both sides with whitish ochreous, along lower half centered 

 with leaden grey. Cilia fuscous brown with a leaden gloss, a dull 

 brown basal line. 



Hindwing rather dark fuscous bronze, paler at base, cilia con- 

 colorous, with a pale basal and a dark subbasal line. 



Female, 19 mm. Fore^ving broader, angle more obtuse, termen 

 less sinuate and less oblique. Ground color paler, lilac grey, more 

 extended, markings more limited, more conspicuous, dark brown. 

 Costa less distinctly suffused with pink. Transverse fascia almost 

 separated in three parts, an oblique costal streak, a horizontal median 

 streak and a dorsal rectangidar blotch; space between basal patch 

 and transverse fascia parted by an interrupted dark brown narrow 

 striga; pale transverse fascia separating apical patch, sometmes ill 

 defined. 



Hindwing fuscous bronze, deeper colored than in male. Otherwise 

 similar to male. 



Male genitalia as described for the genus, differing chiefly by the 

 not modified abdominal sternites. Shallow dorsal organs are present 

 in tergite II. Minor differences of the genitalia proper are the shape 

 of the tegumen which is higher, with a triangular median process in 

 asynthetes; imcus is much smaller and clavate; socius longer, its top 

 reaching above the shoidder of tegumen. The shape of the valvae 

 and their appendages is but slightly different. 



Female genitalia show clear-cut differences from those of G. erotias. 

 In that species the collicidiun is twice as narrow and the signum is 

 reduced to its basal plate only which is concave and finely scobinate, 

 slightly resembling the signum in certain Bactra species.

Externally rather similar to 0. erotias, differing by whitish-ochreous 

 edges to some markings. In the male of that species there is only 

 one round white dot in center of disc, corresponding with the posterior 

 end of the upper pale edge of the median portion of the transverse 

 fascia; in erotias there is also no distinct apical patch, the terminal 

 fourth of wing being rather unicolorous and paler, traversed by
