with Mdiumbu in the los.s oi' tliu iiroxiuuil pair ol' sjiiii's on the iiindtibia and also 

 in pattern, has the sexual armature of the S similar to that of some African 

 VohjptijchuK, the clasper not beinj^ divided, and hearing a patch of friction-scales, 

 the eighth tergite having a corresponding organ of friction, the tenth sternite being 

 divided, the penis-sheath bearing a lateral tooth, and there not being an}' processes 

 above the jienis-funnel. This African IJkoma is clearly a derivation from an 

 African I'olifjitj/chus, while the Oriental (and Palaearctic) Marumha are derived 

 Iniiu an Oriental Polyptj/ckus. The absence of tlie proximal pair of hindtibial 

 spurs does not mean closer relationship between ^f((r^lmba and Likonmi\\&n between 

 these and l'o/>//jfyc/ii(s, hnt is (he outcome of parallel development; the tendency 

 of the spurs to become olditerated is obvious in all groups of aseman^iphorous 

 Sjiliinyldae. 



The pattern of the wings is very uniform, varying only in details in thedifterent 



species. Forewing : a subbasal and three or four antemedian lines, the latter 



more or less convergent behind ; a discal line at (seldom) or beyond end of cell, 

 immediately followed by one or two feeble lines ; three postdiscal lines, more or less 

 strongly tO-shaped (on right wing ; (\)-sba{)ed on left wing), curving round a 

 double spot situated upon M" and SM- near angle of wing, one of these three lines 



mostly vestigial. Hindwing with double sjiot before anal angle as remnant of a 



postdiscal band. 



On the underside we find no lines in the basal half of the forewing, while the 

 hindwing bears three lines between tlie base of M- and distal margin, the most 

 ])roximal one being as a rule accompanied distally by vestiges of one or two more 

 lines, of which one is often ratlier distinct. 



Tills similarity in pattern misled Hamj)son to unite under ^f. (h/rns no less tluxn 

 five distinct species. 



Key to the species : 



a. Foretibia ending in a long thorn or claw 24U. ^^. indicHs. 

 Foretibia witiiout apical thorn ... b. 



b. Hindwing red ..... 230. M. gasclikeiritschi. 

 Hindwing burnt umber-brown, russet, 



tawny, ochraceous, or buff" ... c. 



c. Costal and distal marginal areas of hind- 



wing ochre-yellow .... 236. M. muacki. 

 Costal and distal marginal areas of hind- 

 wing not ochre-yellow .... d. 



(I. Distal margin of forewing concave be- 

 tween SC^ and R^, apex almost 

 truncate ....... j. 



Not obviously concave ..... e. 



e. The most distal brown line of underside 

 of hindwing absent, or barely vestigial, 

 but its white border distinct ; fore- 

 wing below with sharply defined 



tawny or ochraceous apical area . 237. M.janfiowskii. 



The most distal brown line of hindwing 

 distinct, or forewing below without 

 tawny apical area ..... f.
