104 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, 



five 01- six indistinct small whitish spots ; inner marginal fold glossy 

 pale grej'. 



Palpi, thorax, and abdomen beneath uniform dull whitish. 



2 . Uniform pale dull brown. Fore wing : discal macular series 

 as on underside of male in position and arrangement, but larger, 

 whiter, quite distinctly defined, and subvitreous. Underside. — 

 Very slightly tinged with yellowish. Fore wing : discal spots as on 

 upperside. Hind wing : discal spots more distinct than in male. 



This exceedingly obscure little species is distinguished from 

 P. hottentota by its much duller (and in the male darker) upperside 

 without any yellowish suffusion, and by the want (in the male total) 

 of jellow colouring on the underside, as well as by the small size, 

 separateness, and whitish tint of the discal series of spots on the 

 underside of the hind wings ; the whitish instead of yellow tint of 

 the underside of the palpi and body is also a distinction, and the 

 marked prolongation of both the fore and hind wings more resembles 

 that presented by P. monasi. Trim. The colouring of P. occulta, 

 however, is not nearly so dark as thnt of P. lugens, Hopff., which is 

 also a larger butterfly, with broader and blunter wings, and has the 

 underside almost as dark as the upperside. But for the almost 

 entire suppression of the discal spots of the fore wings in the male, 

 P. occulta looks much like a miniature of P. fatuellus, Hopff. 



1 have received two Transvaal males of this insect, one without 

 locality or date, but the other captured at Barberton by Mr. C. F. 

 Palmer early in 1888 ; and a third, taken at Potchefstroom by 

 Mr. T. Ayres, which differs from all the rest in being totally devoid 

 of the usual small indistinct spots.
