I. Notice of Indian Insects exhibited at last meeting hy Mr Elliot of 
Wolfelee. By R. F. Logan, Esq. 
Although not present at the last meeting of the Society, 
when Mr Elliot's beautiful drawings of Indian animals by 
native artists were exhibited, I have since had the pleasure 
of inspecting them, through the kindness of Dr Coldstream ; 
and with reference more especially to the entomological 
portion of the collection, I wish to bear testimony not only 
to the intrinsic beauty and fidelity of the drawings, but also to 
their high scientific value, as comprising the transformations 
of many insects whose history has been hitherto unknown 
to science. Besides figures of the larvae and pupse of many 
of the Papilionidce, Pieridoe^ Nymphalidce, &c., some of 
which have been already figured and described, the collec- 
tion includes some most interesting details of the trans- 
formations of the Heterocera. Among the Noctuce., those of 
the genera Hypocala, Hyblcea, Ophideres, Achaea, Lagop- 
tera, and Serrodes, are especially worthy of mention. The 
larvse of Hypocala have no apparent afiinity with those of the 
Catocalidce, immediately before which they stand in Guenee's 
arrangement. Those of Ophideres, of which Guenee re- 
marks, "e/e desirerais vivement connaitre les chemilles de ce 
genre singulier," are quite as remarkable as the perfect in- 
sects. They are elongate and cylindrical, like those of the 
OpjMusidcB, and the anterior pair of ventral claspers is imper- 
fect ; but instead of being attenuated posteriorly and ante- 
riorly with a pair of small tubercles on the eleventh seg- 
ment, the latter forms a large conical protuberance, as in
