order that entomologists may recognise the species if found 
in England in that state. The perfect insect is so well known 
that it has not been thought worth while to figure it, particularly 
as itis so large that its wings would extend beyond the width 
of the letterpress of this magazine. The larva feeds on 
several species of Asclepias, viz. A. tuberosa, curassavica, 
cornuti, and purpurascens: no species of the Asclepiadacez 
is indigenous to this country; one genus of the order, 
Periploca, is often grown in the open air, and many of the 
genera under glass. Mr. Riley states that according to some 
authors the larva also feeds upon Dogbane (Apocynum): but 
one genus of the Apocynacee is indigenous here, viz. Vinca; 
both V. major and minor are common in Mid-Sussex in the 
woods and in gardens; but whether the larva would feed 
upon either of these plants must remain an open question at 
present. The oleander, another Apocynaceous plant, is also 
very commonly grown in Sussex, with slight shelter during the 
winter. The colour of the larva is black, white, and yellow. 
Mr. Riley states that the females certainly hybernate, and 
deposit their eggs in his district, St. Louis, early in May ; 
the imago appears about the middle of June; eggs are 
then again deposited, and a second brood of the butterfly 
appears in October. It is quite possible that the larva may 
be found to feed here on some indigenous plants of quite 
different orders to those which it usually frequents, and this 
becomes the more likely, as it would form by no means an 
exceptional case; Bombyx Mori, for instance, can be reared 
by feeding it either on lettuce or mulberry,—plants belonging 
to orders as widely different as any two arranged amongst the 
Exogens.
