Mr. Westwood also mentioned that a monstrosity similar to the 
latter case was described in Der Natur for seller, observed in a 
specimen of Centra vinula; and contended that the observation of 
M. Wesmael absolutely proved that the head of the imago was 
contained within the head of the larva, and did not occupy two 
segments as asserted by Dr. Ratzeburg and Mr. Shuckard, this 
opinion being still maintained by the latter. Mr. Newman stated 
that immediately previous to moulting the head of the enclosed 
larva was to be found beneath the first segment of the body, and 
entirely disengaged from within the head of the still enveloping 
skin. Mr. Westwood contended that this was not to be consi- 
dered as a proof that the head of the enclosed larva occupied the 
head and anterior segment of the old skin, but that it was the 
necessary result of the disengagement of the enclosed larva from 
its surrounding membrane, and of the endeavours used by the 
enclosed larva to effect a passage by its head through a fissure 
down the back. Mr. Shuckard, on the other hand, considered it 
not impossible that the membranous covering of the first segment 
of the larva in M. Wesmael’s specimens might have shrivelled up, 
leaving the head of the butterfly enclosed in the head of the larva 
alone, and not in the head and first segment, as it ought to do 
according to the theory of Dr. Ratzeburg. 
Mr. Westwood also gave an account of the Canon Schmidber- 
ger’s observations on Psilus Boscii, contained in Kollar’s work on 
insects obnoxious to vegetation recently published, [and included 
in Miss Loudon’s Translation of that work published subse- 
quently.]
