NOTES AND OBSERVATIONS. 



Small Example of Phigalia pedaria. — I have a specimen of 

 P. pedaria measuring only fifteen-sixteentlis of an inch in expanse. Is 

 not this exceptionally small for the species ? The specimen was taken 

 on a tree-trunk at Walthamstow on Jan. 21st, 1894. — E. Cornell;

Sesia conopiformis in Britain. — We have been informed by Mr. 

 Dale that the Sesia he recorded as this species (Entom. xvii. 245) was 

 wrongly determined, and that so far he has not been able to reconcile 

 the specimen with any known species of the genus. — Ed. 



Was Clostera anachoreta introduced ? — In Mr. Meyrick's new 

 work I observe that, under the above-named species, the author says : — 

 "Perhaps introduced, but temporarily naturalised in Kent and Nor- 

 folk." Will Mr. Meyrick kindly explain how he harmonises this 

 statement with the fact that the original specimens, captured in the 

 larval state at Saltwood, and bred by Mr. Sidney Cooper in 1858, 

 remained in that gentleman's collection as C. curtula until after his 

 visit to Mr. Doubleday in 1860 ? If Mr. Cooper did not introduce 

 them, has Mr. Meyrick any idea as to who did introduce them, and 

 for what purpose ? And does Mr. Meyrick suppose that if Mr. Cooper's 

 captures had been determined and reported in, say 1858 or 1859, their 

 authenticity would have been called in question ? — H. G. Knaggs ;

Hybernation of the Larv^ of Colias hyale. — I have read with 

 interest Mr. Williams's note (Entom. xxix. p. 128) respecting the 

 hybernation of the larvffi of Colias hyale, as it so closely coincides 

 with my remarks upon the larvae of this species (Entom. xxv. p. 271 ; 

 xxvi. p. 145) when I pointed out that the larv» were capable of passing 

 the winter in complete hybernation. The decisive manner in which my 

 larv?e entered into hybernation, resting upon a layer of silk spun for 

 the purpose, remaining in a hybernated condition for three months, and 

 living for 121 days after entering into that state, is sufficient proof 

 that this species is capable of hybernating in the larval state, which 

 I fully believe to be its usual habit. — F. W. Frohawk ; April, 1896. 



Sugar v. Honeydew. — Prof. Clowes and Dr. Sudborough, of Uni- 

 versity College, Nottingham, have kindly promised to make a quanti- 

 tative analysis of honeydew, if it can be procured in sufficient quantity, 

 with the view of discovering whether some substance more attractive 

 to moths than sugar or treacle can be produced artificially. Ento- 

 mologists interested in the matter are asked therefore to collect leaves 

 covered with honeydew and send them, before the middle of July, as 

 freshly gathered as possible, to Prof. Clowes, University College, Not- 

 tingham. As large a quantity as possible should be sent, so as to 

 give enough for an investigation. — F. C. Woodforde. 



Notes on Various Insects. — Encyrtus elpis, Walk. This has been 

 bred from Lichtemia viband^ the ivy Coccid, by my friend Mr. Richardson. 

 — Eypcecilia alismana, Rag. This species used to stand in our lists as
