MICROLEPIDOPTERA OF PHILIPPESTE ISLANDS 55 



of diverse length. Thorax uith or without a posterior crest. Pos- 

 terior tibiae normally scaled. 



Fore wing without a fold, veins 8 and 9 stalked, approximated or 

 separate, upper parting vein usually present, from before base of 

 10 to beyond that of 8. Usually a field of modified scent scales in 

 male on the underside, along and beyond the posterior part of lower 

 edge of cell. On the upper side usually a pale semioval costal patch. 



Hind wing mth 2 from beyond middle, 3-5 approximated, 3 from 

 angle, 6 and 7 closely approximated towards base, usually an extended 

 circidar patch of scent scales in center of disc on the upper side. 



Male genitalia with uncus developed, single and rather slender 

 or paired, lobes sometimes moderate and densely hairy. Socius 

 usually developed, pending or porrect, seldom parietal. Gnathos 

 well developed, sclerotized, sometimes rigid and porrect, ^^ith a 

 broad hook part. Valva characteristic, slender and narrow, sacculus 

 ending "with a triangular prominent point with one or more spines, 

 a marginal series of strong bristles below point, an isolated and elevated 

 Spc2 sometimes present. 



Beside the type species, I attribute the following species to the 

 present genus, judging from the characters of the male genitalia.

 Argyroploce hucaspis Mej^ick, 1902, in Gardiner, Fauna Maldives . . ., 



vol. 1, no. 7, p. 126. 



Two more species have already been attributed to Statherotis by 

 Clarke (1958, vol. 3, p. 595, pi. 296), viz., 

 Proschistis agitata Meyrick, 1909, Journ. Bombay Nat. Hist. Soc. 



vol. 19, p. 589 (Ceylon), and 

 Argyroploce aspidias Meyrick, 1909, ibid., p. 599 (India). 



Finally, two more species, assigned by Meyrick to Statherotis, 

 should be removed from this genus, as already correctly stated by 

 Clarke : 



"Statherotis" catharota Meyrick, 1928, Exotic Microlepidoptera, vol. 



3, p. 443 (Andamans), and 

 "Statherotis" relapsa Meyrick, 1928, ibid., vol. 3, p. 444 (Ceylon).
