Type, staudingeri, Mab- 



Anteuiice : club rather flattened, sickle-shaped, the thickening 

 and tapering very gradual, terminating in a fine joint. Fore wing : 

 male with a costal fold ; cell more than tw'o thirds length of fore 

 wing ; upper discocellular minute ; middle and lower discocellulars 

 inwardly oblique, the middle the longer ; vein 9 equidistant from 8 

 and 10 ; vein 2 from near base of wing ; vein 3 about four times as 

 far from 2 as from 4 ; vein .5 nearer 6 than 4. Hind wing pro- 

 duced into a short tail ; vein 5 wanting ; discocellulars barely 

 traceable ; vein .S from just before end of cell ; vein 2 rather nearer 

 to 3 than to base of wing.

5. Genus Tarsoctenus, nov. (Plates I. fig. 6 ; II. fig. 13.) 



Type, ^?«^i«, Hewitson. 



Allied to Phocides. 



Antennae : club moderate, with a slender terminal hook. Palpi : 

 second joint densely scaled ; third joint naked, more prominent than 

 in Phocides. Fore wing : male with costal fold ; cell considerably 

 more than two-thirds length of costa ; discocellulars slightly oblique, 

 middle slightly longer than lower; upper discocellular very short; 

 vein 3 about half as far again from 2 as from 4 ; vein 2 nearer to 

 base of wing than to vein 3. Hind wing with a distinct lol)e at end 

 of vein 1 b ; vein 7 well before end of cell ; discocellulars very faint, 

 slightly outwardly oblique ; vein 5 barely traceable ; vein 3 rather 

 nearer to end of cell than to vein 2 ; vein 2 almost equidistant from 

 base of wing and from end of cell. Hind tibiae in both sexes very short, 

 with only a terminal pair of spurs. In the male one of these spurs 

 is much produced, and the proximal end of the tarsus bears beneath 

 on either side a comb of yellowish bristles which, when the tarsus is 

 straightened out, enclose the lengthened spur. This character is 

 less developed in papias than in the other species of the genus.
