CONTRIBUTIONS TOWARDS THE KNOWLEDGE OF THE 

 COLEOPTEROUS EAUNA OF WEST SUMATRA. ') 



C. RITSEMA Cz. 



A second, third and fourth consignment of insects , sent 

 by Mr. J. D. Pasteur to the Leyden Museum, have recently ar- 

 rived. Besides some Hemiptera, Hymenoptera, Diptera and 

 Orthoptera, all captured in the neighbourhood of Padang 

 Sidempoean (resid. Tapanoeli: North West Sumatra), they 

 contained a more considerable number of Coleoptera from 

 the same locality. ^) These latter belong to the following 

 species several of which were not yet represented in the 

 Leyden Museum, whereas some others certainly will prove 

 to be new to science. Those species which , according to 

 the insect-collection of our Museum , occur also in East 

 Sumatra are indicated by an asterisk , a way of acting 

 which I thought of interest for the sake of our knowledge 

 of the geographical distribution of the Coleoptera in the 

 island of Sumatra, Moreover those species which are des- 

 cribed at a date posterior to the Munich Catalogue are 

 followed up by their citation.

2) The third and fourth consignment contained moreover a beautiful series 

 of Lepidoptera, all captured by Mr. Pasteur himself at Padang Sidempoean 

 (N. \V. Sumatra), at Assahan (N. E. Sumatra), and on his way across the country 

 from one place to the other. In his accompanying letter Mr. Pasteur tells me 

 that none of the specimens are collected in places higher than 100 M. above 

 the level of the sea. Later on I have the intention to give a full list of the 

 collected species.
