PAPILIO LXDRA. 
side of secondaries, not to consider tlie fact that it is a tropical species probably Central 
American or West Indian ; he further adds in continuance “ to which with As ter i us it must be 
closely allied, ” it doubtless stands nearer the Asterius group than to any other, but it is 
distinct enough to stand on its own merits ; we all know that Asterius has on the abdomen four 
rows of spots, two dorsal and two lateral, as also lias P. Sadalus Luc., the Nov. Spec, described 
on the succeeding page, and some other tropical American species of whose identity I am 
not quite certain, whilst in P. Indra the abdomen were it not for the two small lateral dashes 
on the anal segment would be entirely black, moreover instead of a small round spot on each 
side of the collar as in Asterius, not only the sides of the collar but the whole surface of the 
patagise are yellow, of an obscure shade; in this species, on the under side there is not the 
slightest indication of fulvous on the inner bands as is invariably the case with Asterius and 
near allies ; it may also be worth while to note that this is the only tailless American Papilio 
so far found north of Mexico. 
Mr. Hidings captured at the same time with Indra, examples of Asterius, which differed 
in nowise from those found in other localities ; iu connection with this fact I would quote what 
Mr. W. C. Hewitson whose authority few would be inclined to dispute, says: in Proc. Zool. 
Soc. of London, 1859, ‘‘ that two insects differing but slightly are most likely distinct species 
if they come from the same locality ; but if they come from a distance they arc most likely the 
same species changed by the difference of locality.” As no illustration accompanies the 
original description, nor has any since been published, 1 thought it might not be amiss to 
head my second plate with a figure of this pretty insect. I believe I have now said all I at 
present know in regard to this species, which is one of the few out of the many described by 
Heakirt that will be able to hold its own. 
PAPILIO ANTICOSTIEXSIS, NOY. SI\ 
Male. Expands 2f inches. 
Antenna*, head aud body black', a small yellow spot behind each eye, two larger spots 
of dull yellow on back of collar, patagise dusky yellow, four rows of yellow spots on abdomen, 
as in Asterius. 
Upper surface black, primaries with two rows of yellow spots running parallel with the 
exterior margin, the outer one composed of eight spots, of which the three nearest the apex 
are round and nearly of a size ; the next four arc oval and a little larger ; the last one is gem- 
inate; the spots composing the inner band are nine in number, and much larger; the one 
nearest the costa is oval, and not inline with the others, being nearer the discal cell; the 
second one is an oblong triangle, almost divided at the inner end by a black dash ; the next 
five are also triangular, and increase in size as they near the interior margin ; the eighth is 
the largest, and square in form ; the ninth is narrow ; a yellow discal bar ; fringes alternately 
black and yellow.
