Show 104 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, five or six indistinct small whitish spots ; inner marginal fold grey. Palpi, thorax, and abdomen beneath uniform dull whitish. 2 . Uniform pale dull brown. Fore icing : discal macular series as on underside of male in position and arrangement, but larger, whiter, quite distinctly defined, and subvitreous. U N D E R S I D E .- Very slightly tinged with yellowish. Fore wing : discal spots as on upperside. Hind icing : 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 \ellow 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 iustead 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. I 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. Omrora (August), Otiembora (November-December), and Okavango River (December).
