1877.]} BUTTERFLIES FROM DUKE-OF-YORK ISLAND. 145 
17. CyREsTIS FRATERCULA. 
Exp. 2-2. Allied to C. acilia, Godt., from New Guinea, of which 
it is doubtless an insular race. The white band crossing both wings 
is comparatively narrow, and is drawn to a point at the costa of the 
anterior wings, and also as it approaches the anal angle of the hind 
wings. The fulvous patch at the same angle is restricted, and only 
surrounds the terminal ocellus. In this respect this race resembles 
C. lelia, Feld., and C. strigata, Feld., from both of which it differs 
in the pointed form of the transverse white band; beneath it re- 
sembles the race we believe to be C. strigata (exempl. in mus. nostr. 
ex Gilolo or Morty, Wallace), except that the white submarginal 
bands of the hind wings are all narrower, 
Two specimens of this Cyrestis are in the collection, both alike as 
to their markings. Though, as we have already stated, but a race 
of C. acilia, it seems as much entitled to separation as several other 
races which have had names bestowed upon them. 
18. Mrinerra, sp.? 
One imperfectly developed specimen of a Minetra probably indi- 
cates that a distinct race inhabits these islands ; but it may be as 
well to defer characterizing it for the present, until more specimens 
come to hand. It most resembles specimens from Bouru and 
Ceram, collected by Mr. Wallace, and which are doubtless referable 
to the Amboyna species M. sylvia (Cram. Pap. Ex. t. 43. f. F, G). 
19. DotescHaLuiaA BRowNI. (Plate XXII. figs. 3, 4.) 
2 Exp. 3-8. Allied to D. australis, Feld. (Voy. Nov. Lep. 
p. 405, t. 51. f. 1,2), but larger; the inner edge of the terminal 
black portion of the primaries, instead of running nearly parallel to 
the outer margin, ends at the anal angle ; a well-defined subtriangular 
black spot at the end of the cell: the secondaries have the two 
black spots as in D. polibete, Cr., but are without either white or 
blue centres. Beneath there are well-defined light marks across the 
cell, beyond it, and in the apical angle ; the base of the secondaries 
has also two light spots of a violet tint 3; two ocelli on the secondaries 
beneath correspond to the black spots of the upper surface. 
We have been unable to find any species exactly corresponding to 
this. It differs from all we have seen, in the black of the primaries 
ending at the anal angle instead of on the inner margin. Both the 
species recently described by Mr. Butler, D. herrichii and D. mont- 
rouziert (P.Z.S. 1875, p. 612), the types of which we have ex- 
amined, appear to be quite distinct from the present insect. 
20. CHARAXES JUPITER. ‘ 
Charazes jupiter, Butler, Lep. Ex. p- 14, t. 5. f. 4, 7. 
This handsome species, of which Mr. Brown has sent a single 
specimen, agrees well with Mr. Butler’s figure cited above. The 
original specimen was obtained by Mr. Wallace at Dorey, New 
Guinea.
