Ehibitions, &c. 
Mr. Douglas made some further remarks on the “ Corozo nuts,” known 
as vegetable ivory, exhibited by him at the last meeting, which were 
attacked by a beetle belonging to the genus Caryoborus. The attention of 
the officials of the Dock Company had been drawn to the serious loss of 
weight that would be found when the nuts were to be delivered, and they 
were anxious to ascertain if there was any mode of arrestiug their depreda- 
tions, and whether the beetles lived and bred among dried nuts, or entered 
the kernel in an earlier stage. It was suggested that the mischief originated 
in the parent beetles laying their eggs in the nuts when still in a green or 
soft state, and as there were several larve in each nut the interior was 
completely destroyed. The metamorphosis took place inside the nut. 
Mr. M‘Lachlan, in connexion with the above, exhibited another species 
of palm (Copernicia conifera), from Rio Janeiro, forwarded to him by 
Professor Dyer, which were also infested with a species of Caryoborus 
(C. bactris, Linn.). In this case each nut served as food for a single larva 
ouly, which bored in it a cylindrical hole of considerable size and depth. 
Mr. E. A. Fitch exhibited the seeds of a leguminous plant (an article of 
commerce) imported from Egypt, infested by a Bruchus, which was esti- 
mated to cause a loss of 50 per cent. to the owners. 
The President exhibited the larva of an Australian species of Hepialus 
(he believed from Queensland), bearing a fungus with four or five different 
branches, issuing from the back of the neck and the tail. Also, a fungus 
growing from the back of a Noctua pupa. 
Mr. Fryer exhibited a curious variety of one of the Geometride, believed 
to be Melanippe rivata.
