exhibiting any variation. Xni/cuiia jilipendidac — Of fair size, bnt not 

 (lift'ei-ing from British examples. This was the rarest species of the 

 five common ones. Zytjaena hmiccrac. — Of large size and common, 

 but showing no variation. One five- and one six-spotted species with 

 red abdominal rings have not yet been determined. 



It must be borne in mind tliat these captures were all made in two 

 mornings. The most I could do was to sample the insects met with, 

 as my space was limited. Many small species, therefore, were 

 probably overlooked, and many others not differing from our British 

 examples were discarded. These latter, of course, are not included in 

 the above, as I bear only the faintest recollection of them. 



i^CIENTIFIC NOTES AND OBSERVATIONS. 



AiTTNiTiEs OF Ei'iNEPHELE TiTHoNus, — An observatiou that I made 

 on the habits of Cocnonymplia airania, in the woods at Gresy-sur-Aix 

 at the end of July last, leads me to ask for the gift or loan of an egg, 

 larva and pupa of K. tithonus. This observation was simply that 

 C. airania has exactly the same habits on the wing as K. titJionux, and 

 that I carelessly netted three or four specimens of the former under 

 the impression that they Avere of the latter species. In my recent re- 

 arrangement of these species {BritisJi Butterflies, p. 376) I included 

 K. tithonus in the same genus as 7'A ianiya, Avith some amount of doubt, 

 which that casual observation made at Gresy increased. I have since 

 examined the ocellated spots critically, and am inclined to think that 

 tithonus is much nearer the genus Coeiionijiiqilia tlian that of Kpinepluie. 

 I should be glad of pupae and larv® whenever obtainable, for descrip- 

 tion, and to confirm or correct this view. I observe that Dr. Jordan 

 made an identical observation [K.M.M., xvi., p. 89) on the similarity of 

 habit between L'. an-ania and E. tithonus. — J. W. Tutt. 



On the colour of the cocoons of 8aturnia pyki. — I was in- 

 terested in your remarks (ante, pp. 195-6) about the cocoons oiS-jii/ri. 

 Those I found outside are both darker and harder than those which 

 spun in my possession. The larviu seem to me to spin a light-coloured 

 cocoon, and then to consolidate it by secreting a dark Huid, which " felts " 

 thesilk. Thelarva, which pupated in a paper " poke " at Bourg d'Oisans, 

 is not only lighter, but not so hard, as the others. — E. Harrison, 

 Eosetta, Peebles. 



Number of eggs laid by Dasychira pudibunda. — A female J>asi/(hira 

 jnulibunda, which I took in vop. on a beech-trunk at 7 p.m. on the 14th 

 May, had laid 274 eggs by 5.10 p.m. the following day. I counted 

 these three times to ensure accuracy. — William Hewett, Howard 

 Street, York. 



Porthetria dispar at light. — I omitted in my note on the habits 

 of this species {ante, pp. 208 — 209) to mention that the males came 

 freely to the lighted windows of the hotel where I was staying, at 

 Bourg d'Oisans, from about 8 p.m. to 9 p.m. No females were at- 

 tracted. — J, W. Tutt. 



Queries as to TEniRosiA bistortata (chepusculaiua) and T. 

 CREPuscuLARiA (biundularia).— As I am working at these species, I 

 should be glad of information from as many entomologists as possil)le re 

 the following (j[uestions : — (1). The earliest and latest dates on which they 

 have taken either of these species '? (2). When they consider each species 

 to be in its prime ? (3). Is T. biundularia ever double-brooded with
