habit between all species which hybernate is natural enough, but above all 
because of all the numbers of Triphosa subaudiata 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 weeks 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 Vanessce. 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 more — 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 27M, 1891. [I 
do not think sex in any way influences the development, which 
proceeds during copulation in both sexes. — Ed‘.] 
Retarded development 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 
Acro?iycfa ( Viminia) myriccB which emerged two days before the wings 
comm.enced to develop, and after so long they developed perfectly. —

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.
