and by J. 0. Westwood for the generic. With the latter Newport

name, morphology, habits, etc., of Melittobia. There can be no doubt 
that Westwood’s genus, very briefly characterised in Proc. Ent. Soc. 
Lond. for 5th July, 1847, p. xviii, must stand. The part of the pro¬ 
ceedings containing this page was published on 12th January, 1848.

description of M. aoasta, and as, besides, I am at present engaged in 
revising the whole genus, it does not seem necessary to say much on 
the habits of the insect. M. acasta is markedly polyphagous; never
