A very rare species, in fact about the most difficult to obtain 
of all the European butterflies. I describe it from the single 
specimen in my collection, and have seen only four others.

Eatiier small white-winged butterflies, with orange patches at 
the tips of the fore wings. Antenns proportionately shorter than 
in the last genus, and with larger clubs. Thorax and abdomen 
stouter than in Euchloe, and markedly covered with down. 
Larva stout, pubescent, and slightly tapering towards the 
extremities. 
Pupa short, terminating anteriorly in a blunt point, and 
posteriorly in an arched tail. Attached by the tail and by a 
transverse band, and enveloped in a slight silken web, somewhat as 
in Parnassms. 
Such are the principal characters by which Rambiir separated 
Papilio Eipheme of Esper from the preceding generic group. 
There are only two European forms, and these are closely 
allied : they were long regarded as variations of the same species ; 
even now a more extended knowledge of the earlier stages may 
compel us to reunite them. They were first separated by Meiietries 
in 1832. These insects are very local, being confined in Europe 
to those districts which border upon the Mediterranean and 
Black Seas.

Expands from 1*50 to 1-80 in. Wings generally pure white, 
but sometimes with a yellowish tinge. The fore wings have a 
black crescentic spot at the extremity of the discoidai cell, and at 
the tip a black patch dusted on its outer side with yellow, and 
having within it a bright orange blotch of an oval shape, and above 
this a white spot. Hind wings white, blackish at the base, and 
showing the pattern of the under side. Under side : — Fore wdngs
