406 A Preliminary Bevision of the Genus Trisuloides 



sericea, though the basal hair is much less strongly developed than in 

 the type-form. 



Genitalia (pi. XVI, fig. 6) : — 



Valve as in sericea. Process shorter and less strongly chitinized 

 and toothed. 



Central Buru : Kako Tagalago, 2,700 feet, May, 1922, nine $ #, four 

 $ $ ; also one $ from Central West Buru : Gamoe 'Mrapat, 5,000 feet, 

 March-April, 1922. 



But for the difference in genitalia this subspecies might have passed 

 as an aberration of sericea trigonoleuca, of which there is unfortunately 

 insufficient material for a close study, but on the strength of the genitalia I 

 have ventured to regard the slight difference quoted above as subspecific. 



5. Trisuloides albiplaga Warr. (A very distinct-looking species, which 

 may possibly, when dissected, be found to belong to yet another genus.) 



Tambana catocalina Moore may possibly belong here ; the type of 

 polyphaenaria Warr. (sunk by Hampson to catocalina) agreeing well 

 with albiplaga in the structure of antenna ( ? ). But it is so distinct 

 from all other Trisuloides species that in the absence of the $ its 

 correct position must remain extremely doubtful. 



Genus 4. Smilepholcia gen. nov. 



External characters (pi. XVII, figs. 5, 6) : — 



Palpus curved, compactly scaled ; segment 1 narrow, rather short, 

 flattened at base (slightly bifurcate). Wings slightly glossy. Fore wing 

 broad, with cell about one half-length of wing. Hind wing yellow. 

 Abdomen robust, with the crests on 3 and 4 generally well developed. 

 S antenna bipectinate to nearly three-fourths ; $ antenna shortly 

 bipectinate. 



Genitalia : — 



Valve lanceolate, toothed process on the inside, this process 

 lanceolate. Penis not armed with cornuti. Uncus long and narrow, 

 slightly curved, apex without a beak. 



1. Trisuloides luteifascia Hamps. (Type.) 



Genus 5. Tambana Moore. 



External characters (pi. XVII, figs. 11, 12) : — 



Palpus curved, compactly scaled ; segment, 1 very short and 

 broad, flattened at base (bifurcate). Wings moderately glossy. Fore
