42. Genus Thanaos. 

 Thanaos, Boisd. Icones, 240 (1832-1833). Type, tages, Linn- 



Antennae : club moderate, more or less bent into a curve, bluntly 

 pointed. Palpi porrect ; second joint laxly clothed; third joint 

 almost concealed, bluntly conical. Fore wing : inner margin longer 

 than outer margin ; male with a costal fold ; cell of fore wing less 

 than two-thirds the length of costa ; discocellulars slightly inwardly 

 oblique, the lower the longer ; vein 3 shortly before the end of 

 cell ; vein 2 slightly nearer to base of wing than to end of cell. 

 Hind wing : outer margin evenly rounded ; vein 7 very close to end 

 of cell ; discocellulars and vein 5 faint ; vein 3 immediately before 

 end of cell ; vein 2 almost equidistant from end of cell and base of 

 wing. Hind tibiae fringed and with two pairs of spines, the upper 

 pair minute. 



This genus as it stands at present includes many species which 

 are certainly not congeneric. The above description is taken from 

 the type specie?.

Subfamily III. Pamphilin^e. 



Section A. 



AntenucB very varied, never much hooked, and usually sharply 

 pointed. In all the genera in which the tip of the antennae is blunt 

 the epiphysis on the fore tibia is wanting, excepting in one or two 

 Australian forms. 



Palpi : third joint usually short and inconspicuous, in some few 

 genera long and slender ; in these it is also always erect and never 

 porrected horizontallj^ in front of the face. 



Fore wing : cell always less than two-thirds the length of costa ; 

 vein 5 slightly nearer to 4 than to 6, except in some aberrant Aus- 

 tralian forms, in wliich it is slightly nearer to 6. Hind wing never 

 with a conspicuous tail or tooth, though frequently more or less 

 lobate ; vein 5 never well developed. 



Male never with a costal fold and only comparatively seldom with 

 a discal stigma on the fore wing ; frequently with glandular patches 

 and tufts of hair on the wings ; never with a tuft on the hind tibice. 



The epiphysis on the fore tibiae and the medial pair of spurs on 

 the hind tibiae are occasionally wanting. 



Confined almost entirely to the Old "World. As far as is known 

 the species of this group rest with their wings raised over their backs, 

 assuming that position immediately on settliug.
