Sale of M. Audouin’s library. —I have just received the cata¬ 
logue of the library of M. V. Audouin, which will be sold by auction, 
at Paris, on 10th to the 25th of May. The catalogue itself forms a 
volume of 176 pages, and forms a most valuable addition to 
entomological bibliography. The works are arranged systematic¬ 
ally instead of alphabetically, and certainly constitute a far more 
complete entomological library than has ever before been offered for 
sale. This may be easily conceived when it is mentioned that there 
are not fewer than seventy-four separate treatises on the honey-bee, 
and more than one hundred and fifty on the silkworm and silk 
culture. In addition to the works strictly on entomology and general 
comparative anatomy and physiology, there are numerous works on 
the other classes of animals. Copies of the catalogue may be seen 
at the Linnsean, Zoological, and Entomological Societies. 
Insects of Central India. —I have been favoured by Lieutenant 
Colonel Hearsey, a gentleman who for more than thirty years has 
been stationed in the very centre of India (Saugor), with a sight of 
his very extensive and valuable collection of insects formed in that 
part of our Eastern territories. The collection is especially rich in 
Sphingidie and nocturnal Lepidoptera—vast numbers of which 
were reared from the caterpillar state. The species of the modern 
genus Papilio are but few’ in number and w T ell known. P. Hector 
(extremely rare), Pammon, Polytes: respecting the specific identity 
of the two last-mentioned insects, Colonel H. partially confirms the 
statement of Boisduval, having observed one chasing the other con 
amove. I w r as surprised not to find a single species of Lucanus, nor 
Fulgora, in the’collection ; which, however, includes a new’species of 
Paussus, and of Diopsis, a very minute species of Apotomus, 
specimens of both sexes of the interesting ITymenopterous genus 
Trirogma, a number of very English-looking Harpalidsc, various 
Bolboceri and Athyrei, as w T ell as most of the species described and 
figured by Mr. Saunders, in the Transactions of the Entomological 
Society (vol- iii. part 1, plate 5) ; Colonel Hearsey having commu¬ 
nicated them to Mr. Prinsep, from whom Mr. Saunders received 
them.
