The same member also exhibited a large Curculionideous insect 
from Brazil, from between the prothorax and elytra of which two 
very long and clavate fungi had been produced, one of which was 
entire, the other branched. A figure of this insect is given in 
plate III. fig. infer. 
Mr. Children exhibited specimens of a caterpillar from New 
Zealand, from the back of the neck of which a long dry vegetable 
protuberance had been produced, accompanied by the following 
notice respecting it : — “ The grub of New Zealand, in appearance 
resembling that of a large caterpillar. It lives entirely on the 
sweet potato (Convolvulus Batatas , L., or Kumera of the New Zea- 
landers). During the season it continues healthy and active, but 
ultimately dies ; it retains its natural appearance, but becomes dry 
and hard, when an appendage sprouts from its tail, from four to 
six inches long, resembling a small twig.” With the view of ex- 
citing inquiry into the particulars of the growth of this vegetable, 
which was believed both by Messrs. Robert Brown and J. Bennett 
to be most probably a species of Clavaria, : \ he mentioned that O. 
F. Muller had published a memoir on the subject of vegetable 
excrescences found upon animals, all of which, however, were 
dead at the time of their discovery ; but that Dr. Mitchell had 
published a paper in Silliman’s American Journal, in which he 
stated that he had noticed many similar instances, especially in a 
wasp’s nest, the larvae of which were not full grown, but that inci- 
pient vegetation had commenced in the bodies of these larvae, 
which, however, continued growing, as well as the vegetable sub- 
stance within their bodies, until the latter burst out and killed the 
* Dr. Klug has described and figured another but very different species of Clialcis, 
under the name of C.albicrus, produced from the pupa of another species of E uplica 
(E. Chrysifpus ) in the Symbolic Physicic. Insects, pi. 37, fig. 9. Say also obtained 
Clialcis amce.na from the pupa of a Tliecla ( Journ . Boston N.H. Soc. 1, 271), and
