MICROLEPIDOPTERA OF PHILIPPINE ISLANDS 163 



Male genitalia: It may be sufficient to describe the differences of the 

 male genitalia of Syntomaula simulatella with those of S. microsperma. 

 Sclerite of the eighth tergite with a longer and sinuate process, and with 

 two short processes (ventral and dorsal) instead of one. Tegumen is 

 similar, but left process of uncus is longer and strongly clavate. 

 Aedeagus longer. Anellus rounded A\ith a small notch at the top (in 

 microsperma regularly conical). Cucullus longer. Two slender proc- 

 esses, hairy at the top, which I identified previously as anellus lobes, 

 actually are not connected with anellus but are appendages of the 

 costal edge of the valva. 



Female genitaha, which have not been described before, are compara- 

 tively little modified. Seventh and eighth segments moderately 

 sclerotized. 0\apositor and apophyses very long. Sterigma shaped as 

 a simple round cup. Ductus bursae for a short stretch simple, thence 

 double, a strongly plicate blind sack at the left, and the ductus proper, 

 plicate above, simple beneath; corpus bursae large and ovoid. Signa, 

 two large and straight thorns with funnel-shaped bases. 



ScaeothyriSf new genus 



Head flattened, with dense appressed scales, very dense and long on 

 vertex. Ocellus small, posterior. Proboscis developed, dilated and 

 flattened at base. Antenna 3/4, slightly thickened, serrulate, short- 

 ciliate, scape elongate, rather stout, with long pecten. Labial palpus 

 moderate, little curved, median segment thickened, not reaching base 

 of antenna, terminal segment slender, acute, shorter than median 

 (thorax damaged). Maxillary palpus short, slightly brushy, appressed 

 to proboscis. Posterior tibia with smoothly appressed long and bristly 

 scales, projecting beyond apex. 



Forewing moderate, oblong, pointed, termen slightly rounded, very 

 long and oblique; without tufts of scales. Vein lb long-furcate, 2 from 

 beyond 4/5, 3 from far before angle, 4 from angle, 7 and 8 long-stalked, 

 7 to costa, 11 from before middle. 



Hindmng semioval, shghtly over 1, cilia 1/2; a corrugated, trans- 

 versely striated thin patch below 1/3 of cell, lower edge of cell thickened 

 and strong, vein 2 from 2/3, strongly bent at base, 3 from angle, 4 and 5 

 long-stalked, 6 and 7 parallel. 



Type species: Scaeothyris pseusta, new species. 



An interesting addition to the peculiar subfamily. The genus is 

 characterized by the long-stalked veins 4 and 5 in the hind wing. It 

 is nearest to Archisopha Meyrick, differing by the presence of an an- 

 tennal pecten, by shorter palpi, smooth posterior tibiae and neuration 

 of the hindwing.
