NOTES ON THE INDIAN SPECIES OP HYPOPHLOEUS, Fabr. WITH 

 DESCRIPTIONS OP NEW SPECIES. 



BY K. a. BLAIR, B.Sc., F.E.S. 

 (Published by permission of the Trustees of the British Museum.) 



In addition to tlie National Collection in the British Museum, this 

 paper is based on the extensive Indian material in the collections of 

 Messrs. H. E. Andrewes and Gr. C. Champion, together with that 

 supplied by the Forest Zoologist, Dehra Dun, India, at whose request 

 the determination of the Indian species of this genus was undertaken. 

 The types of new species, when not alread}^ in the National Collection, 

 have been generously presented by their respective owners. 



The beetles belonging to this genus are found beneath tlie bark of 

 dead or dying trees very frequentl}^ in association with different species 

 of " bark-beetles," Scolytidae. It is probable that the beetles, or more 

 likely their larvae, are predaceous on the larvae of the Scoli/tidae, though 

 possibly they frequent their galleries only for the purpose of feeding on 

 the exuding sap and detritus contained in them (Stebbing, " Indian 

 Forest Insects," 1914, pp. 236, 510). It is very desirable that accurate 

 observations should be made to determine this point.
