tives of Asia, Africa and Australia, selected from the cabinets of our 
most zealous collectors of exotic Coleoptera, 1 could have had but 
little hope of being able in a few months’ time to record the exist- 
ence of a number of additional species of the same family, from one 
of the same quarters of the globe. Nevertheless, the indefatigable 
exertions of Mr. Wallace, who has recently started on a natural-history 
excursion to Singapore and the islands of the Eastern Archipelago, 
have enabled me to give a supplement, containing not fewer than 
twelve new species, to my former memoir, all of which were collected 
by that gentleman within a few days after his arrival at Singapore ; 
proving how rich must be the harvest which he is likely to reap, 
should his health be spared, in that and the adjoining countries. 
The species of Cleride which he has sent home furnish us with a 
clue to several important points connected with the geographical 
distribution of the family in question, belonging as they do exclu- 
sively to two genera, Omadius and Stigmatium, which are thus 
proved to have their metropolis in that quarter of the world. It is 
true that the species now about to be described do not possess the 
splendour of many of the Brazilian, or even European species of the 
family, their specific distinctions consisting of variations in the mark- 
ings of the elytra, which it is almost impossible to describe in words, 
and which can only be satisfactorily represented by careful figures. 
Some variation in form also occurs in several of the species, and I 
have also observed variations in the structure of the antennze in most 
of the species beyond what might be regarded as sexual. One of the 
species of Omadius is especially distinguished in this respect, from 
having several of the central joints of the antennz furnished with 
long curved sete, such as I have not elsewhere observed. 
Mr. Wallace has not at present supplied any notices of the habits 
of the species received by his agent in this, his first consignment ; but 
as all the specimens are specifically numbered, I have no doubt that 
he possesses notes concerning them with which I hope to be favoured 
before this article goes to press. 
From the specimen now given an idea may be obtained of the rich- 
ness of the collection which Mr. Wallace has already formed. I may 
allude, however, to the families Carabide and Anthribide, which 
contain many new and remarkable forms, especially among the smaller 
species. We may therefore trust, that when he reaches Borneo and 
the adjacent islands, we shall receive from thence many very interest- 
ing novelties.
