The following paper was read:—


(Annulosa, Pl. XXXVIII.)

Having lately submitted to the notice of the Zoological Society a memoir containing descriptions of fifty new species of Cleridæ, na-

tives of Asia, Africa and Australia, selected from the cabinets of our most zealous collectors of exotic Coleoptera, I could have had but little hope of being able in a few months' time to record the existence 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 Cleridæ 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 exclusively 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 markings 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 antennæ 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 antennæ furnished with long curved setæ, 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 richness of the collection which Mr. Wallace has already formed. I may allude, however, to the families Carabidæ and Anthribidæ, 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 interesting novelties.
