Notes on the Localities given in Longicornia Malayana, 

 with an estimate of the comparative value of the 

 collections made at each of them. By Alfred R. 

 Wallace. 



In order that students of this work may not be misled 

 by considering the materials on which it is founded to 

 be more complete than they really are, especially as 

 regards the geographical disti'ibution of the species and 

 the comparative richness or poverty of the several islands, 

 I think it advisable to give a short sketch of each locality, 

 an account of my opportunities for obtaining Goleoptera, 

 and especially Longicorns, and an estimate of its pro- 

 bable richness compared with other districts in the 

 Archipelago of nearly equal extent. I take the localities 

 and islands in the order in which they are arranged in 

 the foregoing tables. 



Penang. The small collection from Penang consists of 

 a few insects given me by Mr. Lamb on my way home, 

 and of a few more collected by a native sent there by a 

 friend. It gives no idea of the productions of the island, 

 which, however, are probably not very numerous, as a 

 large portion of it is more or less cultivated. The 

 opposite coast of the Province of Wellesley has produced 

 many fine and remarkable Longicorns, as may be seen 

 by Mr. Pascoe's paper, published in the Proceedings of 

 the Zoological Society for 1866. 



Malacca, Mount Ophir. I spent about two months 

 collecting in the interior of Malacca, ten days of which 

 were passed at Mount Ophir ; but I found no very good 

 localities for insects, and accordingly devoted most of 

 my time to Ornithology. Many parts of the country are 

 covered with fine forests, and ought to be very produc- 

 tive if well worked under favourable conditions. 



Singapore. My chief collecting ground was at Bukit- 

 tima, a Roman Catholic Mission Station in the centre of 

 the island. Here were several patches of forest on the 

 tops of low hills, and on one of these, about a square mile 

 in extent, I obtained nine-tenths of my Singapore col- 

 lections. A few statistics of these may be interesting. 

 The first day I went out, I captured eleven species of 

 Longicorns ; in a fortnight I had sixty species ; in a 

 month near 100 species, (besides 140 Rhyncophora out of
