GO MR. R. TRIMEN O^ BUTTERFLIES FROM [Jan. 16, 



marginal edge, from 1st median uervule to anal angle, an extremely 

 fine black line. 



$ . 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. Underside. — 

 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-mar- 

 ginal black line well-marked, continuous from apex to 2nd median 

 nervule. Hind wing : an additional small black diseal 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 concolorous, 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 wants 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. pucllaris cannot be separated from 

 D. aslauga and D. hildegarda ; and most probably, therefore, its 

 close ally D. puella should be withdrawn from the genus Teriomima, 

 Kirby, and transferred to Durbania. 



Mr. Selous's four specimens were all taken at the Vunduzi 

 Kiver, 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 Pentilatropicalis.

The only example, a male, was 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 bv Mr. Selous in 1884 on the Umfuli
