16. Genus Trichosemeia. 



Trichosemeia, Holland, Ann. Nat. Hist. (6) x. p. 294 (1892). 



Type, subolivescens, Holland. 



Antennae : club moderate, evenly curved. Palpi porrect ; third 

 joint short, obtusely conical. Fore wing : inner margin longer than 

 outer margin ; cell less than two-thirds the length of costa ; vein 12 

 reaching costa almost opposite end of cell ; discocellulars slightly 

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

 of cell ; vein 2 twice as far from end of cell as from base of wing. 

 Hind wing evenly rounded ; vein 7 very close to end of cell ; disco- 

 ceUulars and vein 5 barely traceable; Acin 2 immediately before 

 end of cell ; vein 3 considerably nearer to end of cell than to base 

 of wing. 



Male : no costal fold on fore wing, but with a large patch of 

 appressed scales on the upperside of the hind wing, occupying the 

 basal half of the wing from the costa to the middle of cell. The 

 inner margin of the fore wing on the underside is also clothed with 

 modified scales, presenting a silky appearance, and bearing a tuft 

 of hairs attached to the submedian near the base. The hind tibiae 

 are flattened, and bear a tuft of hairs attached along their inner 

 surface. 



There are three species of this genus in the British Museum from 

 W. Africa, two being unidentified, and the third being pidvina., 

 Plotz. All these three species present slight modifications in the 

 extent of the sexual patches on both wings, and in pulvina the hind 

 tibiae are only fringed, and exhibit no trace of the tibial tuft. 



17. Genus Tagiades. (Plates I. fig. 9 ; HI. % 11.) 



Tagiades, Hiibner, Verz. p. 108 (1816). Type, japeius Cram. 



Pterygospidea, Wallgr. Rhop. Caffr. p. 53 (1857).; 



Type,Jlesus, Fabr. 



Antennee : club slender, bent at about a right angle, terminal 

 portion rather long. Palpi porrect, third joint minute. Fore 

 wing: iimer and outer margins subequal ; cell less than two-thirds 

 the length of costa; vein 12 reaching costa well before end of cell ; 

 discocellulars suberect, the lower the longer ; vein 3 shortly before 

 end of cell, three times as far from 2 as from 4 ; vein 2 almost 

 twice as far from end of cell as from l)ase of wing ; lower margin of 

 cell between origins of veins 2 and 3 strongly arched. Hind wing 

 evenly rounded ; vein 7 well before the end of cell, about twice as 

 far from 8 as from 6 ; discocellulars and vein 5 very faint ; vein 3 

 shortly before end of cell, twice as far from 2 as from 4 ; vein 2 

 considerably nearer to end of cell than to base of wing. Hind tibiae 

 Jringfd, and with two pairs of S[)nrs. 



It is cpiite impracticable to separate Plerj/ffospidea from Tor/iridcs, 

 the oidy dilference being that in Jlesiis tlie outer margin of the 

 fore wing is slightly excavated jn^t above the outer angle, which is 

 not the case in jupelus ; when, however, one tries to a])ply this
