Exhibitions, iC-c. 



Mr. Douglas made some further remarks on the " Corozo nuts," known 

 as vegetable ivory, exhibited by liim 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 arresting 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 wlien still in a green or 

 soft state, and as there were several larviB 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 [Coperiiicia cSnifera), 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 

 only, 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 Geometridic, believed 

 to be Melanippe rivata. 



Mr. M'Lachlan, on behalf of Dr. Atherston, of South Africa, exhibited a 

 pair of a very singular Orthopterous insect (belonging to the Acrydiidie), 

 which, in colour and in the granulated texture, so exactly mimicked the 

 sand of the district as to render it almost impossible to detect it when in a 

 quiescent state. The name of the insect was uncertain, but it was supposed 

 to approach the Trachyptera scutellaris. Walker. Also some singular oval, 

 flattened cases, open at each end, and from six to eight lines in length.
