248 Descriptions of New Species of Rhopalocera. 
to the middle of the inner border of the secondaries. The 
apical angle of the primaries is acute and salient owing to 
the outer maryin being slightly concave towards the point. 
The anal angle of the secondaries, too, is acute. 
Papilio eracon, sp. n. 
Alis saturate eneo-nigricantibus, ciliis inter venas ochraceis ; 
anticis maculis sex submarginalibus, ad angulum apicalem evanes- 
centibus, viridi-ochraceis; posticis paulo nitentioribus, maculis sex 
discalibus fere rotundis et punctis sex (horum duobns inter venam 
medianam et ramum ejussecundum)submarginalibus viridi-ochraceis: 
subtus fuscis; anticis ad basin nigricantibus, maculis tribus ad angu- 
lum analem aliisque indistinctis cirea cellule finem ochraceis; posticis 
maculis septem transversim elongatis nigro limbatis rubidis et inter 
eas punctis glauco-albidis, extra eas punctis sex majoribus submar- 
ginalibus ochraceis; abdomine supra ochracea segmentis nigro 
marginatis, corpore toto subtus fulvo maculato. Exp. al., 5-0 in. 
Hab. Mexico occipEenTaLts, Colima (Mus. Staudinger). 
A male of this distinct species differs from all forms of 
this section of Papilio found in Central America in having 
the spots of the secondaries in a submarginal series away 
from the cell and the costa, and beyond them are some 
small submarginal spots. Beneath the coloration of the 
margin of the secondaries is very marked ; besides the 
usual black margined rufous spots there are whitish spots 
between them, as well as ochraceous ones next the 
margin. 
Papilio iopas, sp. n. 
P. copane similis sed anticis supra omnino immaculatis posticis 
fascia maculosa angustiore a margine externo magis remota. Exp. 
al., 4:55 in, 
Hab. Mexico occiprentatis, Colima (Mus. Staudinger). 
A single male specimen sent us by Dr. Staudinger 
seems sufficiently distinct from P. copanx to require a 
name. It is still more distinct from the Papilio from 
San Blas which we described and figured as P. procas 
(B.C.A. Rhop., ii., p. 203, t. 65, figs. 15 and 16), which has 
a few spots on the primaries near the anal angle, and a 
sie discal band to the secondaries, part of which enters 
the cell.
