Of this beautiful species we have as yet only seen three female examples ; but if our 

 surmise as to its relationship with P. montezuma is correct, the male will be found not 

 to differ materially in coloration. Besides its longer tails and deeper dentation of the 

 outer margin of the secondaries, the row of four white discal spots at once distinguishes 

 the species from P. montezuma. P. alopius is found in a district of Mexico which has 

 hitherto been but little explored, so far as its Lepidoptera are concerned ; in other 

 branches of zoology this region presents several peculiar features, so that the occurrence 

 of a new Papilio there is not to us a matter of surprise. 



There is a female specimen in the British-Museum collection, said to be from Mexico, 

 under the uncharacterized name of P. alopius of Gray. This name we now adopt. 



C. P. MYLOTES group.

The fold of the inner margin of the secondaries differs considerably from that of 

 P. iphidamas and its allies; the inner edge of the wing is furnished with long black 

 hairs which are contained in a small fold along the edge of the wing, and the wider 

 inner fold is lined with black scales, but there are no cotton-like hairs as in P. ipJii- 

 damas (Tab. LXV. fig. 9). The foliate appendage to the fore tibia is nearly in the 

 middle of the joint. The harpe is a long rod, curved at its distal end, where it has two 

 strong spines or horns (see Tab. LXV. fig. 9 a). The marginal lunules of the secondaries 

 are red, and those wings have no opalescent gloss. 



This is a group very numerous in species throughout Tropical America, only two of 

 which occur within our limits. These have a very similar range to P. iphidamas and its 

 allies and are found in the same forests.
