534 PROCEEDINGS OF THE NATIONAL MUSEUM vol. loi 



Supplementary characters. — Subspiracular area with or without 

 scales, Preala scaled below knob. Sciitellum with narrow scales. 

 Larval head hair 6 anterior to 5, 4 anterior and mesad of 6, 7 on a 

 level intermediate between those of 5 and 6 (only the larva of harperi 

 is described). Comb teeth few, in a row. Larval habitat: bamboos. 



Included species. — A. albotaeniatus (Leicester), a. var. mikiranus 1 

 Edwards, harperi Knight, lepchana (Barraud) (possibly a synonym 

 of alhotaeniatiis) , and stevensoni (Barraud) . 



Discussion. — This subgroup is probably not a completely homogene- 

 ous unit, since alhotaeniatus, a. var. mikiranus, and lepchana all 

 possess a postspiracular scale patch ; and harperi and stevensoni lack 

 it. Until all the larvae are known, it will probably not be possible 

 definitely to decide this point. For a recent discussion of this sub- 

 group see Knight (1948b). 



Subgroup II, PAPUENSIS 



Definition. — Australasian. Basistyle without a tuft of specialized 

 scales (males of alticola and derooki are unknown). Claspette fila- 

 ment bladelike in lateral view. Male palpi as in Subgroup I. Female 

 tori not scaled, except in anggiensis (female of clintoni unknown). 

 Vertex dorsum with at least median longitudinal band narrow 

 scaled. Scutum marked with either a large area or a median longi- 

 tudinal stripe of pale scales (either silvery white or golden) on 

 anterior two-thirds, this pale area sharply delimited laterally and 

 posteriorly from surrounding dark scaled areas. Ppn with narrow 

 scales above (may be none in dohodu7Ms) , broad below (only narrow 

 scales present in anggiensis, toxopeu^i, and alticola). Postspiracular 

 area with or without scales. Paratergite scaled (except derooki). 

 Hind tarsi with broad basal pale bands on at least first four segments, 

 sometimes on all five, no apical pale scaling. Neither femora nor 

 tibiae sprinkled with pale scales anteriorly. 



Supplementary characters. — Scutellum narrow scaled. Subspiracu- 

 lar and prealar areas with or without scales. Larval head hairs 4, 5, 

 and 6 in a small anterior group, hair 7 behind or level with the pos- 

 terior margin of this group. Larval habitat : Tree holes, rot holes, 

 rock pools, fallen leaves, artificial containers, and a variety of other 

 small water-holding containers in forested areas. The larvae of 

 alticola, anggiensis, clintoni, derooki, and toxopeusi are undescribed. 



Included species. — A. alticola Bonne-Wepster, anggiensis Bonne- 

 Wepster, argenteitarsis Brug, clintoni Taylor, derooki Brug, doho- 

 durus King and Hoogstraal, hollandius King and Hoogstraal, noval- 

 hitarsis King and Hoogstraal, palmarum Edwards, papuensis (Tay- 

 lor), suhalhitarsis King and Hoogstraal, and toxopeusi Bonne- 

 Wepster.
