NOVITATES ZooLoaicAE XXIV. 1917. 431 



angled on R', becoming oblique inward anteriorly, but here usually weak or 

 obsolescent ; double subterminal line grey, rather weak, the proximal more or 

 less broken into spots, course similar to that of postmedian but with the angle 

 at R' less strong ; terminal line fine, continuous ; fringe white, with slightly 

 smoky central and distal lines (sometimes with their interspace also somewhat 



smoky). Hindwing marked almost as in aegretta Feld., but wthout proximal 



line. 



Underside white ; costal edge of forewing tinged with ochreous. 



Natal, common, the type cJ from Durban, in coll. Brit. Mus., ex coll. 

 Guentzius. Also from British East Africa, Pemba Island, Zanzibar, East 

 Griqualand, Uganda, Sierra Leone, etc. 



Probably the cf mmonest African species of the genus, though only hitherto 

 made kno^nl through Walker's very brief description. Misidentified by Warren 

 as aegretta, the true aegretta being his digammata as pubhshed, though his earlier 

 manuscript, used by Kirby, had applied the name digammata to the present 

 species. 



7. Problepsis similinotata spec. nov. 



cJ, 34-38 mm. Extremely like the preceding, of which nearly the whole 

 description is appMcable. Face less clear white (more fuscous-mixed) in lower 

 part. Antennal pectinations rudimentary throughout. 



Forewing with the discal mark broader, its outer side being farther frcm 

 cell and nearly or quite connected by some ochre-yellow shading with the end 

 of the longitudinal streak of R' (the general contour thus more recalling that of 

 meroearia Saalm., Lep. Madag. 218. t. 5. f. 67) ; postmedian line stronger, rather 

 brighter ochreous ; proximal subterminal spots thickened between the radials 

 and between M' and SM'. 



Upper Congo: Yakusu, May 1900, type; Bopoto, May 1903. Both in 

 coll. Tring Museum, collected by Rev. Kenred Smith. 



A ? from Ogriiga, River Niger, Avith terminal line obsolete, probably also 

 belongs here, though rather smaller than would be expected for that sex (scarcely 

 34 mm.). 



8. Problepsis aegretta insculpta subsp. nov. 



o, 42 mm. ; ?, 46 mm. Larger than aegretta Feld. [Reise Novara, Lep. 

 Het. t. 128. f. 14), from South Africa, all the markings stronger. 



Forewing with the outUnes of the ocellus complete, olivaceous brownish, 



edged proximally from SC to M with black. Hindicing with the proximal 



and distal sides of the silvery cell-mark connected along the base of R' by a 

 silver streak. 



Escarpment, British East Africa, 6,500-9,000 ft., March 1901, <? type; 

 January 1901, ? (W. Doherty). Also a slightly worn example from Toro, 

 Uganda, January 1902 (F. J. Jackson). All in coll. Tring Museum. 



Probably Guenee's htonaria {Spec. Gen. Lip. x. 14) was a worn ? of aegretta, 

 which varies in the direction of weakened markings even when in fine condition ; 

 his name would take priority.
