but on the whole perhaps coming nearest to Belenois. Many 
members of the genus had been affected by mimicry, and one 
species, P. rubrobasalis, Lanz., was an excellent copy in both 
sexes of the familiar Mylothris agathina, Cram. This was also 
[Ixvi 
the case with the females of the new species, which Mr. Neave 
said he had often mistaken for Jf. agathina when on the wing. 
On the other hand, the males were quite different, showing no 
trace of resemblance to that species of Mylothris. When the 
speaker first looked through Mr. Neave’s captures, he was 
inclined to conjecture that these females were the local 
representatives of P. rubrobasalis, 9, which they closely 
resembled, and that their captor had failed to meet with the 
corresponding males. But he found that Mr. Neave had 
assigned them without hesitation to males of an aspect entirely 
different from that of P. rubrobasalis and M. agathina, and 
that in one instance at least this opinion had been confirmed 
by the capture of paired specimens. On further examination 
there appeared to be no doubt that the resemblance between 
the females of the two species was due rather to the copying 
of a common model than to mere affinity, and that Mr. Neave’s 
species and P. rubrobasalis belonged in reality to distinct 
sections of the genus. Specimens of Jylothris agathina, the 
common model, were included in the exhibit ; also males and 
females of P. rubrobasalis and other members of the genus, 
together with individuals of the new species which were 
actually paired at the time of capture.

Papers. 
Dr. G. B. Lonestarr, M.D., read a paper ‘“‘On some 
Butterflies taken in Jamaica,” and a paper ‘‘On some Butter- 
flies of Tobago,” exhibiting a number of examples taken by 
himself in both localities to illustrate his remarks.
