somewhat ditfiiso, bending rectangularly so as to run to costa, here accompanied 

 distallj' by a small dull reddish spot ; a dark dot in the apical hook ; fringe mostly 



fnscons. Ilimlwing with apex prononnced, termen scarcely bent at R' ; concolor- 



ous with forewing, the line continued as antemedian (obsolete at costal extremity) ; 

 fringe as on forewing.

 discernible ; fringe as above. 



Bitye, Ja River, Cameroons, 2000 ft., September — November 1911. Type in

 53. Conchylia gamma sji. nov. 



c?, 28 mm. Head, body and legs dirty whitish, with a decided tinge of 

 brown. 



Foicwiufi shining white, costal margin with a bright brown streak from 

 towards middle to near apex, pointed at both ends, widening gradually between ; 

 markings brown, forming narrow bars, slightly darker edged ; antemedian from 

 hiudmargiu at 3 mm. from base, ratlior obli([ne to origin of M-, then more curved 

 to cell-fold, along which it runs to join the postmedian, throwing out projections 

 anteriorly and (smaller) posteriorly where it crosses the discocellulars ; postmedian 

 from apex to hindmargin near tornus, forming an inward curve throughout its 

 length, very slightly sinuous ; a thick brown terminal line ; fringe paler 

 (damaged). Hindiciiuj dirty brownish white. 



Forewing beneath smoky, hindwing white. 



Cape : Bushman Land, 1896 (G. Alston). Type in coll. Brit. Mus. 



Distinguishable at a glance by the form of the brown bars, which represent 

 together, when viewed from the apex of the right wing, a rough Greek gamma. 



54. Conchylia Irene sji. nov. 



(f , 28-29 mm. Face white, mixed with light brown. Palpus predominantly 

 brown, the tip (more extended above) remaining white. Vertex and antenna white. 

 Collar mixed with brown. Thorax white ; abdomen more brownish. 



Forewing pure white, less glossy than in the type species ; markings fuscous, 

 consisting of two very slender bars, slightly darker at their edges ; antemedian from 

 SM- at nearly 3 ram. from base, strongly oblii[U(^ and very sliglitly curved, termi- 

 nating at cell-fold near end of cell ; j^stmedian from SM- close to tornus, straight 

 in the direction of ajiex, ending just in front of SC', tapering gradually at posterior 



end and more abrui)tly at anterior; termen and fringe concolorous. Hindwing 



whitish brown, with a not sharj)ly defined fleshy brown border about 3 mm. wide, 

 narrowing towards tornus. 



Both wings beneath smoky brownish, forewing darkened at costa, the lines 

 indistinctly marked in dark grey.
