10 PAPILIO INDRA. 



side of secondarle.s, not to consider tlie fiict tliat it if< a tropical species probably Central 

 American or West Indian ; he fnrthcr adds in continuance " to which with Asterins it must be 

 closely allied, " it doubtless stands nearer tlic Asterius grouj) than to any otlier, but it is 

 distinct enough to stand on its own merits; we all know that Asterins has on the abdomen four 

 rows of spots, two dorsal and two lateral, as also has 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 al)doiiien 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 Asterins, not only the sides of tlie collar but the whole surface of the 

 patagite arc 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 wortli wliilc to note that tiiis is the only tailless American Papilio 

 so far found north of Mexico. 



Mr. Ridings captured at the same time witli Indra, examples of Asterius, wliich differed 

 in nowise from those found in other localities; in 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 are most likely the 

 same species changed by the difference of locality." As no illustration accompanies the 

 original description, nor has any since been published, I 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 

 jn-esent know in regard to this species, which is one of the few out of the many described by 

 Reakirt (hit will be able to hold its own. 



PAPILTO ANTICOSTIENSIS, NOT. SP. 



Malk. Expands 2| inches. 



Antenn:r, head and body black, a small yellow s])ot behind each eye, two larger spots 

 of dull yellow on back of collar, patagi;c dusky yellow, four rows of yellow spots on abdomen, 

 as in Asterius. 



Upper surfiice black, primaries witli 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 are 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 in line with the others, being nearer the discal cell ; the 

 second one is an oblong triangle, almost divided at the inner end by a black dasli ; 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 vellow.
