V. Catalogue of Buprestide collected by the late M. 
Mouhot, in Siam, §c., with Descriptions of New 
Species. By Epwarp Saunpers. 
[Read 5th March, 1866.] 
Bur little was known of the Entomological Fauna of the East 
Indian Isles until Mr. Wallace sent over his large and valuable 
collections, the study of which has given Entomologists a good, 
though of course a far from perfect, knowledge of the insects of 
those productive regions. 
The Entomology of Siam is at present in a less advanced state, 
but the collections sent home by the late M. Mouhot afford at 
least an idea of the fine insects to be found there, and of which we 
should doubtless have received a far greater number had not M. 
Mouhot succumbed to the evil effects of the climate in the midst 
of his entomological labours. Amongst the many beautiful insects 
he collected the Buprestide stand in a prominent position, and I 
have chosen these to form the subject of the present paper, as 
being a family in which I am especially interested; and I think 
that, as the Buprestide collected by Mr. Wallace have been so 
ably described by M. H. Deyrolle, a list of the species obtained 
by M. Mouhot in Siam may tend to increase the knowledge of this 
family, and of the geographical distribution of its genera and its 
species. 
Altogether I find in his collections forty-four species, of which 
I believe thirty-three to be new ; of the remainder, six are speci- 
fically identical with insects collected in the East Indian Islands 
by Mr. Wallace. There are three forms for which I propose to 
create new genera, the first of which, Cardiaspis, should be placed 
next to Dicereomorpha of H. Deyrolle, the second, Engycera, next 
to Melobasis, and the third, Oncomeea, between Brachys and Pa- 
chyscelus. 
On the whole the species seem, as one might expect, to belong 
more to the Indian Fauna than to that of the oriental islands. 
All the species described in this paper are from my own col- 
lection,
