 A male Giraffe and a male Leucorjx, which were to have been in- 

 cluded in the gift of His Highness Ibrahim Pasha, and a fine male 

 Lion, the gift of the Hon. C. A. Murray, died in the transit from 

 Cairo to Alexandria. The remainder of the collection, amounting to 

 18 Mammalia, 14 Birds, and 60 Reptiles, were convej^ed from Alex- 

 andria in the Peninsular and Oriental Company's Steamer ' Indus,' 

 without the loss of a single individual. 



The species presented by Lieut.-Colonel Butterworth were : — 

 Helarctos malayanus. 



Casuarius emu.

Mr. E. Doubleday exhibited specimens of the larva, pupa, and per- 

 fect insect of Sirex gigas, an insect mostly very rare in Great Britain. 

 These specimens were sent to Mr. Gray from Bath by Mr. Brunei, 

 and were accompanied by fragments of the wood on which the larvae 

 had fed. 



It appears that about eighteen months since a quantity of larch- 

 trees were cut in the neighbourhood of Bath, and after having been 

 used as scaffolding-poles in the repairing of one of the churches of 

 the city, were applied to a similar purpose at the railway-station. 

 From these poles thousands of individuals, chiefly females, of Sirex 

 gigas, are now coming forth. From the specimens exhibited, it 

 would seem that the larvae prefer the soft sap wood to the more solid 

 internal part of the trees, penetrating this part longitudinally at a 

 little distance from the bark, the perfect insect gnawing its way 

 through when ready to make its appearance. (Annulosa, PI. XII.) 



Mr. Doubleday remarked that there was here ample evidence to 

 disprove St. Fargeau's idea, that this fine insect is a parasite upon 

 some timber-boring beetles, an opinion already controverted by Mr. 

 Westwood and others. The larva, pupa, and perfect insect are beau- 

 tifully figured by Ratzeburg in his work on insects injurious to forests ; 

 but he gives no details of the habits of the insect, nor any figures in- 

 dicating the mode of Ufe of the larva.
