The unique specimen of this sub-species is unfortunately 

 without any indication of its locality. It is evidently a 

 localized form of P. Sarpedon, remarkable for its small 

 size, the more pointed tail, and the remarkable width of 

 the pale fascia (common to both wings) where the an- 

 terior and posterior wings come in contact; the specimen 

 is a male, with very long white hairs along the anal mar- 

 gin of the hind-wings. The specimen is quite fresh, and 

 there seems no reason to suppose that the fascise and 

 marks on the wings were ever of a green colour, or in 

 fact, different from their present pale straw colour, very 

 slightly tinged in certain points of view with green. The 

 veins in the broad part of the fascia, in both wings, are 

 very pale straw colour. There is a very small concolorous 

 spot on the inner margin of the hind-wing's, near the 

 extremity of the fascia ; the pale lunules near the outer 

 margin of the hind-wings are small and narrow, especially 

 the three outer ones. The markings on the underside of 

 the wings are the same as above, except that the sub- 

 marginal lunules of the hind-wings are suffused with 

 brown scales, and are preceded by a series of five narrow 

 red marks, the innermost of which is in contact with the 

 extremity of the inner margin of the fascia of the hind- 

 wings. In both fore- wings, the membrane between the 

 base of the second and third branches of the median 

 vein, is marked with a dark curved line, inclosing a 

 somewhat triangular space. 



The relationship of this form to P. Sarpedon is indi- 

 cated by its name being an anagram of that name. 



The nearest approach to this form is made by certain 

 New Holland individuals of P. Sarpedon, one of which I
