BREEDING SPHINX CONVOLVULI. 227 



darkening, also the wings at the shoulders. On the 19th the 

 body had also changed colour, and the wing-cases, legs and antennae 

 became very dark, and the eyes quite black. On the 20th the whole 

 pupa had further changed colour, and the following day at 12 o'clock 

 the imago emerged, crippled I am sorry to say, and with a portion of the 

 chrysalis case adhering to the body. The skin of the pupa, when 

 dry, I found to be as thin and almost as transparent as gold-beater's 

 skin. Would one suppose it possible that such a delicate pupa could 

 survive our ordinary winter, and if so, could the very large cavity the 

 larva forms to pupate in assist in preserving it ? 



On the 14th I placed three more pupae in the apparatus, and they 

 remained alive and active. On the morning of December 24th, I noticed 

 in all three of them the alteration in colour of the eyes and proboscis 

 before mentioned. I may mention that to test the apparatus, I put in, 

 on November 27th, a pupa of S. lii/iistri, and found the heat made it 

 very active by the third day — it is now alive and kicking — but I 

 cannot discern much change so far, through its thick skin. 



Of the three pup* placed in the pot on the 14th of December, one, 

 a male, emerged on the 29th at 1 a.m., another, a female, the following 

 morning at 5.30 a.m., the third, also a female, on January 1st, 

 crippled in all but the left fore-wing. 



The specimens are smaller, but greyer and brighter than those 

 (D'Orville's) I already had, and the darker markings are more pronounced. 



The remaining two pupae of .S'. ainndndi I had kept on damp moss 

 beneath a bee-glass, in a room in which there has been a fire daily, 

 intending to leave them there until the summer ; but on finding one 

 dead on January 9th, I decided to force the surviving one, and 

 proceeded to do so on January 12th. I observed — as in the case of 

 the preceding ones — that the change commenced exactly on the tenth 

 day, and a perfect female emerged on January 29th. Kesult : bred 

 one male, four females — of wliich two are crippled and two pupa3 

 dead. 



The Relationship of Endromis versicolor to the Sphingides. 



By A. I3AC0T. 



My interest in this species has been increasing for some years. 

 Entomologists of my acquaintance, who have reared it from the egg, 

 have tantalised me by describing the interesting changes which occur 

 during the development of the larvae. From their remarks and 

 descriptions I had always thought of it as either a misplaced Notodont, 

 or at least a near ally of this group. I was, therefore, rather sur- 

 prised when Mr. Tutt, in discussing my paper on Smerinthus, alluded 

 to E. versicolor as a probable relative of that genus. Mr. Tutt's 

 remarks still further increased my desire to breed it, so that when 

 Mr. Battley mentioned that he had eggs of this species, I intimated 

 that he might " supply a long-felt want," and our secretary, with his 

 usual kindness, gave me some newly-hatched larv£e. 



Fortune and, as will be seen later, misfortune also, seldom come 

 singly ; an offer of eggs from Mr. Clark was therefore hardly a sur- 

 prise. Unfortunately, these eggs, although without doubt fertile (one 

 larva having emerged before I received them), did not hatch, and even 

 the choicest birch that Epping Forest produces could not tempt the
