from China ; yet as his insects were almost all of them Brazilian, 
and its general habit and aspect were that of a tropical American 
type, I concluded that it came from that country, and placed it in 
my cabinet along with my species of Areoda of MacLeay. After- 
wards, being shown by a young lady a collection of undoubted 
Chinese insects, I found amongst them several specimens of Mi- 
mela, one of which she kindly gave me. Upon receiving this, on 
my return to Barham I set about a closer examination ; and upon 
dissection I found, though many of its external characters seemed 
borrowed from South American types, yet that in those which 
were most essential, it came nearest to an Asiatic one, a well 
known species of which was abundant in China ; and others have 
since been discovered in Java, and perhaps in Ceylon. I allude 
to Mr. W. S. MacLeay's genus Euchlora. 
The Brazil genus, of which Mimela assumes the external ap- 
pearance, is Areoda of the same learned author, who has observed 
with regard to Euchlora, ** En genus Asiaticum Areodæe proxi- 
mum*!" But that which I am describing still more nearly re- 
sembles it, wearing as it were its very habit; so much so, that 
at first sight it might almost be mistaken for a small specimen of 
Areoda Leachii. The general colour of the animal; the sculp- 
ture of the head, thorax and elytra; its distinct nasus or cly- 
peus; its labium, labrum, maxillae and legs, are all very similar. 
But in Mimela, as in Euchlora, the mandibulæ are concealed 
under the nasus; whereas in Areoda they are very visible, nor 
have they the dorsal process or tooth observable in the Rutelide. 
In the two former the antennæ consist of nine joints, in the lat- 
ter of ten. In them the posterior lobe of the thorax is more ob- 
solete than in this. In Areoda the last dorsal segment of the 
abdomen is not covered by the elytra; but in Mimela (a circum-
