On the under surface all the spots on both sexes are decidedly 
smaller than in S. Treztschkii. Expanse of wings, g 88 
millim., ? 84 millim. 
Duke-of-Y ork Island. 
Doubtless a geographical representative of S. Tredtschkvt. 
6. Salpinx cenea, sp. n. 
Also allied to S. Trettschkii; slightly larger, the wings more 
produced, the female more bronzy in colour; the whitish spots 
above smaller. Primaries below with a greenish-white spot 
in the cell, and an increasing series of five spots in the trans- 
verse series beyond it (two or three additional spots in the 
female), the fifth spot large and oval, with a bluish or pink | 
tint; female with a pinky-white internal streak and a broad 
whitish internal border: secondaries with a basal white spot ; 
a spot within the cell, the male with six, and the female with 
seven whitish dashes in an angular series beyond the cell; two 
similar dashes (the outer one small) upon the radial interspaces 
and in an oblique line with the angie of the postmedian series. 
Pectus more distinctly white-spotted than in S. Trettschkit. 
Expanse of wings, ¢ 88 millim., 2 95 millim. . 
Solomon Islands. 
A male,apparently referable to typical S. Trectschkit, was also 
in the collection, marked as coming from the Solomon Islands ; 
as the only difference between it and males from New Ireland 
consists in the interno-median streak or spot beg single 
instead of double, I do not hesitate to regard it as that species. 
S. cenea, however, is probably only a race of the same butterfly. 
In the Museum we have a female of this group more nearly 
allied to S. lorenzo, which it may be as well to describe here. 
7. Salpinz viridis, sp. n. 
@. Dark bronze-green ; primaries with a rather large spot 
within the cell, and a larger fusiform spot on the interno- 
median area, shorter than in the preceding species, pinky 
white: secondaries with the costal area broadly greyish; a 
dot near the base of the subcostal interspace, and an increasing 
series of seven conspicuous spots in a slightly bent series 
beyond the cell, the first and last very small, the second and 
third fusiform, the fourth and fifth cordate, the fifth largest, 
the sixth narrower than the fifth, but similarly notched in 
front: body above blackish, spotted in front with white. Pri- 
maries below with the spots much larger, three additional 
spots in an angular series beyond and below the cell : secon-
