430 NOVITATES ZOOLOOIOAE XXIV. 1917. 



scales ; cell-mark brown, tripartite, scmewliat interruptedly edged with silvery, 

 the anterior element (at and beyond apex of areole) crescentic, the posterior 

 (at hinder angle of cell) round, almost completely silver-ringed, the distal (on 

 R') smaller ; median and postmedian hnes formed nearly as in figurata, the 

 teeth smaller ; proximal submarginal spots between R' and hindmargin rather 

 strong, distal small ; terminal line very fine, black, thickened into conspicuous 

 black dots between most of the veins.- — Hindiring without first line ; cell-mark 

 pale brown, silver-edged except in front, reaching from R' to M', its proximal 

 edge sUghtly sinuate anteriorly, its distal gradually projecting to R', then sharply 

 retracted ; markings of outer half corresponding to those of forewing. 



Underside white, ^^-ith the markings scarcely discernible. 



N. Nigeria : Bauchi Province, Panyam, 1910 (G. T. Fox), type S ; Baro, 

 September 11, 1910 (Scott Macfie), paratype $. Both in coll. Brit. Mus. 



5. Somatina virginalis spec. nov. 



S ?. Superficially scarcely, if at all, distinguishable from vestalis Butl. 

 (Ann. Mag. Nat. Hist. (4) xvi. 419), from Natal and the Cape. 6 hindtibia 

 strongly dilated, with a dense hair-pencil, spurs wanting, tarsus greatly abbre- 

 viated (in vestalis the S hindtibia is not dilated and bears a pair of well-developed 

 spurs and the hindtarsus is fully developed). 



Forewing with the dark distal cloudings between the radials, which in 



vest<dis arc often (though not invariably) well developed, weak or wanting. 



Hindwing usually with the discal patch continued (often without narrowing) to 

 the abdominal margin, whereas in vestalis it is only connected with the 

 abdominal margin by a single hne. 



Entebbe, Uganda. Type in coll. Tring Museum. 



More widely distributed than its twin species, occurring in Sierra Leone, 

 Congo, Angola, Unyoro, British and German East Africa, Nyassaland. The 

 range of the two overlaps, for I have before me a single S of vestalis collected 

 by Dr. Ansorge in Kavirondo (Makombi). 



6. Problepsis digammata Kirby. 



Problepsia digammata W. F. Kirby, Ann. Mag. Nat. Hist. (6) xviii. 396 (1896) (nom. nov.). 

 Argyris lalonaria var. Walk., List Lep. Ins. Brit. Mus. xxiii. 807 (1861) (nee. Guen.). 



Face black above, white below. Vertex white. Antenna in <J with short 

 pectinations, commencing as mere teeth, becoming at longest less than twice 

 diameter of shaft, all surmounted with long eolation ; in 9 shortly cihated. 

 Collar tinged with ochreous. Thorax and abdomen white. Foreleg shghtly 

 infuscated on inner side ; hindtibia in o rather long, moderately thickened, 

 tarsus strongly abbreviated (less than one-fourth tibia). 



Foreicing white ; discal ocellus long and narrow, closed posteriorly (just 

 behind M"), open anteriorly (at R'), its proximal side (that on DC) joined 

 anteriorly to a supplementary mark which runs outward along R' for about 

 3 mm. ; the outhnes of these markings fuscous, mixed with metaUic silvery, a 

 filhng-in of ochre-yeDow between base of R' and M' and in the longitudinal 

 streak of R' ; a faint grey line from ocellus to hindmargin ; postmedian line 

 brownish grey, somewhat wavy, a httle incurved between M' and SM', sharply
