liead hairs 4, 5, and 6 very nearly in a straight horizontal line, 7 pos- 

 terior to this line. Comb scales numerous, in a patch. Larval habitat : 

 Rock holes in stream beds, tree holes, and bamboos; less commonly 

 Golocasia leaf axils, water collected on fallen forest leaves, and in 

 artificial containers. The larvae of 'palUrostrls and Hzali are not 

 described.

Snbsroap II, AUREOSTRIATUS 



Depnition. — Australasian, Oriental, and Palaearctic species. Male 

 palpi and basistyle as in Subgroup I (the male of aureostriatus is 

 undescribed). Hind tarsi with all the segments basally banded 

 (III-V appearing all dark in some males of ohinawanus, however), 

 some of the segments also always apically banded, V may be largely 

 white. Postspiracular area unsealed. Paratergite unsealed. Sub- 

 spiracular area scaled. 



Supplementary characters. — Claspettes with a peculiar basotergal 

 lobe bearing specialized scales. Claspette filament a twisted, rounded 

 leaf. Female tori not scaled (may be dark hairs medially). In gen- 

 eral, scutal markings as in Subgroup I, though usually not so distinct 

 and sharp ; in aureostriatus var. greenii the lines are obscured by gen- 

 eral pale scaling. Preala scaled below the Imob. Larval head hairs 

 4, 6, and 7 inserted very nearly in a horizontal line. Comb scales 

 numerous, in a patch. Larval habitat: tree holes and bamboos. The 

 larvae of aureostriatus and a. var. kanaranus are undescribed. 



Included species. — A. aureostriatus (Doleschall), a. var. greenii 

 (Theobald), a. var. kamxiranus (Barraud), and okinawanus Bohart. 



Subgroup III, SINTONI 



De-finition. — Oriental. Male palpi with numerous long hairs arising 

 apically on III and all along IV, some also present on V. Basistyle 

 with a prominent inner tuft of specialized scales. Hind tarsi with 

 narrow pale rings at base and apex of I and base of II, a few pale 

 scales over joints of succeeding segments in some specimens. Post- 

 spiracular, subspiracular, and paratergite areas scaled. 



Supplementary characters. — Claspette filament bladelike. Female 

 tori with pale scales. Scutum with three small patches of pale scales 

 on anterior margin, the lateral patches continued as a pale scaled 

 line on each side to wing base; a line of similar scales from front on
