268 THE ENTOMOLOGIST. 



order that entomologists may recognise the species if found 

 in England in that slate. The perfect insect is so well known 

 that it has not been thought worth while to figure it, particularly 

 as it is 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 Asclepiadace£je 

 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 Apocynacese 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 vvhicli 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.
