338 Mr. A. G. Butler on new Species of 
XLIV.—Descriptions of new Species of Lepidoptera from 
Central America. By ArTauR GARDINER BuTLeR, F.L.S., 
PZ..55, See; 
WE received some time since a species of Morpho, which I 
have been unable to identify with any form hitherto charac- 
terized. It is a very distinct and beautiful species, resembling 
on the upperside, as also in the outline of the wings, M. Mon- 
tezuma and allies; on the underside, however, it more nearly 
approaches J/. Neoptolemus. As I believe this species to be 
quite new, I characterize it as follows :— 
Morpho polybaptus, n. sp. 
Above very like MW. Montezuma: wings greenish blue, 
with a moderately broad black outer border: primaries with 
basicostal area dusky ; a white spot above end of cell; black 
border widest upon costa, which is also black as far as the 
white spot ; an oblique elongate subcostal white spot at inner 
third of external black border, also two apical submarginal 
series of white points, the inner series of four, the outer of 
three points ; fringe spotted with white at extremity of inter- 
nervular folds: secondaries with the outer black border rather 
narrower than in primaries; fringe with two white spots 
between each undulation ; two dull red liture at anal angle; 
abdominal area grey, palest at base: body dull brown; head, 
collar, and pterygodes black ; the external margin of the palpi 
and two dots between the eyes red, two spots on the collar 
creamy yellow, a spot on each of the pterygodes greyish white ; 
antenne black. Wings below deep chocolate-brown, varied 
with pale shining green bands, large red-zoned ocelli, and buff 
and scarlet submarginal bands: general pattern as in J/. Neo- 
ptolemus, from which it differs as follows :—primaries with 
the costal greenish streak red at base; no longitudinal green 
streaks in the cell, but two well-defined transverse streaks— 
the first irregular, oblique, reddish at its lower extremity, the 
second crossing the middle of the cell in a straight line; 
two indistinct, irregular, oblique, subterminal discoidal lines ; 
streaks bounding the lower margin of the cell and the bases of 
the median branches, rose-coloured instead of green ; irregular 
postmedian green band distinct, and nearly equal in width 
from subcostal nervure to the middle of interno-median inter- 
space, where it terminates near the external angle in two rosy 
spots ; an oval oblique subcostal spot above the uppermost 
ocellus ; ocelli with narrower deep orange-red zones; sub-
