 Wallace in the Malay Peninsula?^ and East Indian 

 Islands. By W. W. Saunders, Esq., F.R S., F.L.S., 

 V.-P. Ent. Soc , &c. 



[Read 3rd November, 1862]. 



Baron Chaudoir, in the " Berliner Entomologische Zeitschrift" 

 for 1861, page 116, gives a sketch of the gewvx^ Catascopus, Hope, 

 enumerating the species known at the time, and describing some 

 new species, the results of Mr. Wallace's researches in the East 

 Indies. This genus being a favourite of mine, I carefully examined 

 the species belonging to it received from Mr. Wallace, and it 

 appeared to me that I had several which were undescribed in the 

 memoir alluded to. I placed the whole series aside for further 

 examination, and with a view of describing those species which 

 might prove new, when Dr.Schaum (who has recently visited this 

 coimtry) kindly gave me his valuable assistance, and pointed out 

 to me the species described by Baron Chaudoir ; and it was then 

 apparent, that there were four well-marked forms new to science, 

 two of them remarkable for size and the brilliancy of their metallic 

 colouring. Descriptions of these will be found hereafter. Including 

 the four new species, there appear to be twelve detected by Mr. 

 Wallace, The whole will be found in the following tabular state- 

 ment, which will clearly point out the distribution of the species : —
