habit between all species which hybernate is natural enough, but above all 

 because of all the numbers of Triphosa siibaudiata and dubitata $ ? , 

 which I have found during the months of September, October, and 

 November, resting against the interior walls of the cave ; I have only 

 once met a pair of subaudiata in copula. It was in the month of October. 

 Having enclosed this pair in a roomy box I hoped to get a batch of 

 eggs, but I was disappointed. The female died some weelis later with- 

 out laying. — Ch. Blachier, Geneve. 30 Mars, 1891. 



In the Record, vol i., p. 236, Mr. Tutt has a note on this question 

 more especially with reference to the British Vaiiessce pairing in spring 

 or autumn. In our New Zealand species ( Vanessa gonerilla) the 

 pairing, I think, invariably takes place in spring, as I have frequently 

 observed them in September and October in copula on and about the 

 native nettles, such being the foodplant of their larva. But I have not 

 seen, or known, this species to pair in the autumn. — W. W. Smith,

Imperfect Development of Wings of Bombyx mori. — With 

 regard to Mr. Mackonochie's article on " Wing Development after 

 Copulation," might I call his special attention to the fact that in the 

 case quoted, the specimen of Platypteryx falcula was a female. Had it 

 been a male, I very much doubt whether the development would have 

 taken place, the latter being much more reduced than the former, never 

 indeed long surviving the fulfilment of the purpose for which it was 

 created. Several years ago I reared a number of larvae of Bombyx mori, 

 and many of the pupae hatching simultaneously, several of the insects 

 paired before developing their wings, after which, as far as I can 

 remember, only a few females ever developed them at all fully. — D. H. 

 S. Steuart, 66, Albert Hall Mansions, W. February 27//?, 1891. [I 

 do not think sex in any way influences the development, which 

 proceeds during copulation in both sexes. — Ed.] 



Retarded developiment of wings. — I never saw an insect develop 

 wings at the same rate of speed which Mrs. Bazett noticed in her 

 Chesias spartiata ; but no doubt every one will have remarked the 

 quickness with which the wings on one side often develop, compared 

 with the other side. Insects often wander about for a long time before 

 the wings commence to expand ; for instance, last year, I had an 

 Acronycta ( Viniinia) myriccR which emerged two days before the wings 

 comm.enced to develop, and after so long they developed perfectly. —

 Oligolophus meadii, n. sp., Cambridge, Proc. Dorset Nat. Hist, and 

 Antiq. Field Club, xi., 1890, p. 198, PI. D., figs. 21a, 22. Bloxworth, 

 Dorset. This species is described in a very interesting monograph of 

 the British Phalangidea, which are now brought up to twenty-four in 

 number. Several of the species described do not appear to have been 

 previously recorded as British.
