Show 60 MR. R. TRIMEN ON BUTTERFLIES FROM [Jail. 16, marginal edge, from 1st median nervule to anal angle, an extremely fine black line. 2. Like male, but with the black markings throughout rather larger. Fore wing : apical border broader costally, more deeply indented on upper radial nervule, its inferior linear prolongation in two examples extending below 2nd median nervule. U N D E R S I D E .- Fore wing: two additional subapical black spots, one on costa a little beyond large fifth spot, and the other (larger) below and beyond the same spot and between the radial nervules ; hind-marginal black line well-marked, continuous from apex to 2nd median nervule. Hind wing: an additional small black discal spot, below 1st median nervule ; in one specimen the trace of another, close to costa, near extremity of costal nervure. Head and its appendages black; a ring round eyes, the base and tip of palpi, and a ring round the base of each shaft-joint of antennae, white. Thorax and abdomen pale ochre-yellow. Legs black, conspicuously white-ringed. One female has the underside coneolorous, the hind wings and apex of the fore wings being no paler than the field of the fore wings. Described from one male and three female specimens. This form is distinguishable from Mr. Kirby's description and figure of D.puella, a native of the Gaboon territory, by its larger size, and on the upperside of the fore wings by its want of costal spots beyond the middle, and costally broader internally deeply indented apical border; while on the underside it w7ants two of the black spots present in the hind wings of D. puella, viz. one close to costa about middle, and the other median, just beyond the extremity of the discoidal cell. In all structural characters D. puellaris cannot be separated from D. aslauga and D. hildegarda ; and most probably, therefore, its close ally D. puella should be withdrawn from the genus Teriomimaf Kirby, and transferred to Durbania. Mr. Selous's four specimens were all taken at the Vunduzi Fiver, on the 5th April ; he found them towards sundown settling on the same stems of a blue-flowered plant that was frequented by D. hildegarda and Pentila tropicalis. Genus AL.ENA, Boisd. 107. ALVENA AMAZOULA, Boisd. Alcena amazoula, Boisd. App. Voy. de Deleg. dans l'Afr. Aust. p. 591. n. 60 (1847). The only example, a male, wras captured in the Mineni Valley on the 7th March. It differs from all of the same sex that I have seen in the great enlargement of the ochre-yellow markings, and proportionate reduction of the fuscous clouding in the basi-median area of both fore and hind wings, in this respect resembling the female. A male taken by Mr. Selous in 1884 on the Umfuli |
