HETEROCEEA. 



8. Amesia Trepsiclirois, sp. n. 



(J . Mimics Trepsichrois Verhuellii from tlie same island ; allied to A. stelliffera, 

 of Bliotan and Darjiling (111. T-yp. Lep. Hat., v, pi. Ixxxiii, fig. 8), but on the upper- 

 side all the white spots on the primaries, especially of the sub-marginal series, much 

 larger, more elongated ; the blue border more brilliant than in any known species^ 

 pure ultramarine, without the usual purplish tinge ; secondaries uniformly dark 

 pitchy-brown, with a single sub-apical white spot : on the under-side the differences 

 are more decided, the wings being of a uniform sepia-brown colour, with fewer spots, 

 those in the cell of primaries and the last fire of the discal series being absent ; the 

 other spots are cream-coloured, and, for the most part, much larger than in A. stelli- 

 ffera, but the last of the discal series of primaries and of the sub-marginal series of 

 secondaries are reduced to mere points ; the blue borders and purple reflections are 

 wholly wanting : expanse of wings, 71 mm. 



Island of Nias. 



9. Chalcosia (Enone. sp. n. 



Allied to C. dlstincta, Gu6rin (Delessert, Voy. Ind., pi. 24, fig. 3), but the 

 primaries blacker, with more decided blue shot, the white veins and bands purer, 

 the central band of only half the width ; secondaries with the border more 

 decidedly shot with blue : expanse of wings, 45 mm. 



Island of Nias. 



We have C. dlstincta from "India," Java and Sumatra: it is an 



interesting fact that, as a rule, the Nias species are not identical with 



those of Sumatra.

DESCEIPTIONS OF THEEE NEW SPECIES OP CHARAXES. 

 by h. geose smith. 



Chaeaies Poethos. 



Upper-side black. Anterior- wings with a row of six blue spots, forming a band 

 from near the apex to near the middle of the inner margin, the first spot small, the 

 others gradually larger, the spot on the inner margin being the largest, a blue spot 

 within the cell near the disco-cellular nerTules. Posterior-wing with a similar band 

 of spots from the centre of the anterior margin across the middle of the wing to 

 the fold ; a sub-marginal row of eight minute bluish-white spots, and a marginal 

 thin blue line extending from the inner angle beyond the tail, which is small. 



Under-side resembles Nesiope and Mycerina. This species differs from Nesiope 

 in the position of the blue spots on the upper-side of both wings, and the row of 

 small white spots on the posterior-wing, and from Mycerina in the absence of the 

 broad blue band within the cell of anterior-wing, as well as in the position of the 

 band of blue spots on both wings, and on the posterior-wing in the substitution of 

 the row of small white spots and the thin blue marginal line for the band of blue 

 spots on the margin of Mycerina. Exp. 3 in.
