two, three, fovu-, or six months. As in the case of ova, this must be 

 due to some internal change, a change either in the embryo, or a 

 change in the nutritive material. If it be the former, I do not see 

 how we are to find what that change is, but if it be the latter it will be 

 chemical. It may, for instance, be due to the fact that the embryo 

 can only use this reserve material for food after it has been acted on 

 by a ferment analogous to ptyalin, pepsin, etc., and that it requires a 

 longer time for this ferment to be formed in the ova of Catocala, 

 Ennomos, etc., than in those of Tripliacna fimbria. — Ibid. 



Breeding notes relating to Tephrosia bistortata and T. crepus- 

 cuLARiA. — I am rearing three broods of Tephrosias. Batch I :— 

 (? and 5 , taken on larch trunks, at Leigh (Glos.), April 9th, 

 1897. April 10th : twenty-five ova laid, and moths paired again ; April 

 18th, batch of ova laid ; May 3rd, ova commenced to hatch ; -lune 7th, 

 larvae began to go into moss ; between .June 29th and .July 11th, 13 5 s 

 emerged ; between August 29th and November 10th, oG J s emerged 

 (one or two per day). Batclt II: — S and J, taken at Leigh 

 Woods, April 27th, 1897 : April 29th, ova laid ; April 30th, 

 paired again, and ova laid ; May 23rd, hatched ; .July 2nd, gone in 

 to earth and moss. Batch III, T. crejmscularia ab. (Iclanicrcnsi.s: — Ova 

 from 5 taken at Delamere Forest; laid May 3rd and 4th, 1897; 

 hatched. May 3rd ; July 1st, going into earth and moss. 



The ova of Batches I. and II. were larger than those of Batch III. 

 The ova of Batch III. were not only smaller, but yellower, and more 

 shapeless than those of Batch II. The ova of Batches I. and II. were 

 covered with " fluff." No " fluff" was received with ova of Batch III. 

 The eggs of Batches II. and III. hatched same day, the larviB of No. III. 

 being distinctly smaller. — Chas. Bartlett, 58, Woodstock Road, 

 Redland, Bristol. Oct. 22nil, 1897. 



Note on Phothedes captiuncula. — I believe this species to be a 

 true Miana, from my observations on its larva. It appears to me that 

 Phot/iedes, as a generic name, will have to be dropped. It was given, 

 of course, without knowledge of the larva of the insect. — J. Gardner, 

 F.E.S., 6, Friar Terrace, Hartlepool. 



Habits of ZYG.t:NA exulans. — This species abounded in the Tosa 

 Falls Valley, from July 9th- 16th, this year. The date of emergence 

 turns largely on the melting of the snow. This year the snow was 

 exceptionally deep. Going up the hillside, one first passed the 

 imagines just emerging ; then cocoons, either on stones, generally 

 many together, or on twigs of rhododendrons — the food-plant ; then 

 smaller larvse higher up, and, in the snow itself, young larvae not yet 

 melted out. I dug several from the snow. — W. Bateson, j\I.A., F.R.S., 

 F.E.S., Norwich House, Cambridge. 



Hybernation of Eugonia polychloros. — In regard to the spring 

 appearances of E. polychloros, and the question of its being occasionally 

 double-brooded on the Continent, referred to in the E^it. liecord for 

 October (p. 252), I should like to direct attention to a communica- 

 tion I made to the Evtomolonist's Intcllii/cncer, so long ago as late in the 

 " fifties," in regard to a brood of eggs I had from a captured female 

 in Heptember. A friend who was out with a picnicing party, at May 

 Hill, ten miles from Gloucester, boxed a specimen of /'.'. poli/c/doros, 

 and gave it to me the next day. To my surprise, I found a regular 

 batcla of pinkish-brown eggs inside the lid of the box, as well as the
