LI I. — On Two new Wood-boritig Beetles (Ipidse). 

 By Lieut. -Col. Winn Sampson, F.E.S. 



It is noAv nearly two years ago that I began an exhaustive 

 examination of the Ipidae (until recently called Scolytidcc) 

 contained in the British Museum collection, to which have 

 recently been added the specimens collected by Mr. G. Lewis 

 in Japan and Ceylon. Mr. Ernest Green has aLo been 

 good enough to send a small number collected by himself in 

 the latter country. 



The first description now given is from a specimen in the 

 Fry Collection, the second from two specimens in Mr. Greenes 

 last consignment.
