but in some cases this outer hammock, usually flimsy and 
indeterminate, is really cocoon-like, and has outer lashings. 
I think C. neustria, L., does something like this. This outer 
hammock obviously affords a basis from which to evolve a 
double cocoon. We might go so far as to say that the pad and 
girdle of Papilionids are the cocoon, and that the carpet first. 
spun is the outer hammock. In any case, the outer frame- 
work and the inner true cocoon are a foundation for various 
details to be evolved.” 
SexES OF GONOMETA SUBFASCIA, WALKER.—Mr. J. A. DE 
Gaye, F.L.S., who was present as a visitor, exhibited 5 ¢¢s 
and 8 99s of Gonometa subfascia, Walker, which came from 
the Rev. Lake S. Noble’s collection made in Lagos, 8. Nigeria, 
in 1910. Mr. de Gaye explained how the males were captured 
while they were trying to get into the breeding cage in which 
were two newly-hatched females. Mr. de Gaye further stated 
that he conducted breeding experiments of that interesting 
species in the hope of getting more males, but the larvae died 
shortly after the third ecdysis. In support of the statement 
that the male moths exhibited were those of Gonometa sub- 
fascia, Walker, Mr. de Gaye quoted a description of male 
specimens obtained by Sir Gilbert Carter from bred larvae. 
This description is contained at full length in Mr. W. F. 
Kirby’s ‘‘ Butterflies and Moths,” volume iv, which Mr. de 
Gaye produced. The male Gonometa subfascia is figured on 
page 130. 
Prof. Poutron observed that Dr. Lamborn’s previous experi- 
ences had made it almost certain that, in spite of the great 
difference in size and appearance, these insects were the ¢ and 
2 of the same species, but that this evidence had not been 
considered sufficient at S. Kensington; Mr. de Gaye’s experi- 
ence, however, had now placed the matter beyond doubt. 
PAPILIO DARDANUS, BROWN, FEMALE FORM LEIGHI.—Prof. 
Poutton exhibited the leighi female together with one 
trophonius—two members of a family bred by Mr. G. F. Leigh 
from a female parent of the latter form (Proceedings, 1912, pp. 
exxXiv-cxxxvi). The two female offspring belonged to Mr. D. 
Longsdon, F.E.S., who had kindly lent them in order that 
they might be shown to the Meeting. Prof. Poulton also
