372 MR. H. H. DRUCE OX XEW BUTTERFLIES [Feb. 15, 



to be near Tanuetheira timon Fab. *, but unlike that species has 

 only four branches to the subcostal nervure in the fore wing. 



I have named it after Mr. S. A. Neave, whose researches in 

 the Congo regions have already revealed so many new forms 

 of insects. 



Epamera sibella, sp. n. (Plate XXXY. fig. 2, <$ .) 



Male. Closely allied to E. bellina Plotz, from which it differs 

 by the upper side being violaceous blue without the greenish 

 reflections, by the large shining patch on the hind wing being 

 paler, and by the almost total absence of the black at the anal 

 angle of the hind wing. On the under side the orange areas near 

 the anal angle are much less extensive and do not reach the 

 black line above the lobe. The front of the head is bright 

 orange. 



Expanse 14 inch. 



Hab. Bitje, Ja river, Cameroons, 2000 ft., dry season (G. L. 

 Bates). 



Type, Mus. Druce. 



I have compared this insect with the type of E. iaspist, which 

 according to Prof. Aurivillius equals E. bellina Plotz £. The 

 orange head distinguishes it at once. In that respect it is like 

 E. iasis Hew. § 



Epamera gemmarius, sp. n. (Plate XXXV. fig. 3, <5 •) 



Male. Closely allied to E. sappirus mihi |[. Differs in the 

 shade of blue which closely approaches that of E. laon Hew., in 

 the much less concave inner margin of the fore wing, and by the 

 reduced area of the shining patch on the hind wing. On the 

 under side the ground-colour is whiter, but the markings, though 

 paler throughout, are the same as in E. sappirus. The front of 

 the head is white. 



Expanse Ij inch. 



Hab. Bitje, Ja river, Cameroons, 2000 ft., dry season (G. L. 

 Bates). 



Type, Mus. Druce. 



This may prove to be a varietal form of E. sappirus, but the 

 totally different colour and different shaped inner margin to 

 the fore wing seem to point to another insect.

 p.' 104 (1890) ; id. Trans. Ent. Soc. 1890, pi. xviii. fig. 5. 



Male. Differs from the typical form by the orange on the 

 fore wing spreading along the inner margin almost to the angle
