Lye. pi. ii. pp. 2 1887) in recognizing the M S . genus Tingra, Boisd., with T. tropi-ccdis, Boisd., as type, or in taking the same author's M S . species Pentila undularis as the type of Pentila, a genus first defined by Westwood (Gen. Diurn. Lep. p. 503) in 1851. Although West-wood undoubtedly places P. undularis first on the list of species included under Pentila, it is equally certain, on studying his diagnosis of the genus, that the characters he gives are not those presented by undularis, but are (out of the four species he names) solely applicable to the second species, viz. P. abraxas, Westw.,which should therefore be held as the type of Pentila. With P. abraxas, P. tropicalis is unquestionably congeneric, and the M S . genus Tingra should consequently be abandoned, Westwood defines Pentila as having "labial palpi very minute ;'"' in the fore wings, "upper discocellular arising from the postcostal at about the same distance beyond the second branch as the space between the first and second branches ; it is also about equal in length to the same space and oblique; middle discocellular short, less oblique ;" and in the hind wings, " lower discocellular nearly transverse and Aery slender, &c." P. abraxas presents these important characters, as well as all the others described by AVestw-ood, whereas P. undularis has rather long, slender, and porrect palpi; the upper discocellular nervule of the fore wings so exceedingly short as to be scarcely distinguishable, and the middle one very short and quite transverse; and in the hind wings an open discoidal cell, the lower discocellular nervule being wanting altogether. The different arrangement of the discocellular neuration of the fore wings gives P. abraxas a long discoidal cell and P. undularis a short one. Butler {I. c. p. 60) recognizes that P. undularis " differs considerably both in neuration and palpi from the other species associated with it," and also that, if no longer held as type of Pentila, a new genus would have to be founded for it. 103.

The examples collected by Mr. Selous (three from the Mineni Valley, one at the Lopodzi Fiver, and three near the Vunduzi Eiver) resemble the variation from Mombasa, named lasti by Messrs. Smith and Xirby (op. c^.Lycaen. Afr. pi. viii. figs. 1-4,1889), in the better development of the upperside fuscous border and discocellular spots in the fore wings of both sexes, but want on the upperside the common discal series of small spots (reproducing that always present on the underside) described and figured in the Mombasa examples. As regards the macular hind-marginal border on the upperside of the hind wings of the male, it is observable |
