16. Genus Trichosemeia. 



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



Type, suboUvescens, Holland. 



Antennae : club moderate, eTciily 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- 

 cellulars and vein 5 barely traceable; vein 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. Tlie 

 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 tibite 

 are flattened, and bear a tnft 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 pulvina, 

 Plotz. All these three species present slight modifications in the 

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

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



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



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

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



Type, Jlesus, Fabr. 



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

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

 wing : inner 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 base 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 

 fringed, and with two pairs of spurs. 



It is quite impracticable to separate Pterygospidea from Tagiades, 

 the only difference being that in Jlesus the outer margin of the 

 fore wing is slightly excavated just above the outer angle, which is 

 not the case in japetus ; when, however, one tries to apply this
