was received, with others, from the New Forest in August last; the batch 

 fed well together, and they commenced to spin up on Sept. 6th, completing 

 that operation by the 16th. Both larvae and pupae were kept out of doors. 

 This species is, I believe, somewhat erratic in its times of appearance, a 

 few larvjE in a brood sometimes feeding up more rapidly than their fellows 

 in the spring, and producing imagines in August and September; but what 

 can have induced this misguided creature to quit its pupa in this dull damp 

 weather in the middle of November is beyond my comprehension. — Robert

Stauropus fagi partially Double-brooded, — From ova of Stauropus 

 .fagi, placed in sleeves on oak and apple in June last, I have reared four 

 imagines, the first emergence being on Steptember 11th, the last on 

 October 28th. In none of its stages had fagi been subjected to artificial 

 heat. These facts have led to an outdoor search in its known haunts, with 

 the result that three were taken during the week ended Saturday last. —

Variation of Zyg.icna filipexdul^. — Referring to your article on 

 variation of Z.fiUpendulce, I would say that the var. which T have named 

 cerinus is not of very unfrequent occurrence here, and has been recorded 

 more than once, I think. In some years several will be met with, and then 

 it will not be seen for a long time. Another form also occurs here, in which 

 the brilliant crimson of the spots and hind wings is replaced by a dull 

 pinkish red. Of this form I have both bred and taken examples (Y. N. vii. 

 192), and in 1889 my friend Mr. Gardner bred four or five. I have two 

 examples of the form with only five spots on the upper side, but they both 

 have six on the under side. — John E. Robson ; Hartlepool, Oct. 7, 1891. 



PsycHE PULLA. — In answer to Mr. Briggs (Entom. 243), I should say 

 that, as a rule, the larva of this species certainly does not hybernate full- 

 fed ; I have taken them in the spring, and had to feed them for over a 

 month. My dates for the emergence of the perfect insect (this year) were 

 June 22nd to July 22d, or thereabouts. — Louis B. Prout ; 12, Greenwood 

 Road, Dalston, N.E., Oct. 10, 1891. 



Preserving PuPiE through the Winter. — As we have now reached 

 a period when the ripest time for pupae is just over, and are thinking of the 

 best means by which they may be preserved, I can recommend a plan 

 which I have myself tried for two years with very fair success, and, 

 although it has probably been used by other entomologists, I have not heard 

 of its being in general practice. My plan is this : get one of those improved 

 larva breeding-cages, and, having taken away the sliding bottom, insert a 

 piece of perforated zinc or wire gauze, lay the pupae on this on damp moss, 

 and fill the tins below with water ; these, I may say, should be refilled once 

 a month. In a cage such as this the pupae may be kept in an ordinary 

 living room, as the water by its evaporation will keep them from drying up, 

 or emerging before the proper time. — J. Lewis Bonhote; Rev. W. I).

Material wanted for Physiological Investigation. — I am very 

 greatly in want of a number of dead pupae and larvae for a series of physio- 

 logical investigations in which I am engaged, and shall be much indebted to 

 any readers of the ' Entomologist ' who will be kind enough to forward me
