In July 1901 Mr. C. G. Rogers obtained a few of 

 n;^j,„l *. 5r,v'/^/„ these beetles from the wood of a 



Sampson, sp.n. Uarjeehng. Life History. railway sleeper of Qnerciis lauiellosa 



cut in the Darjeeling forests. The 

 insect evidently oviposits in the timber of this tree, but nothing further 

 is at present known about its life history. 



Undetermined Platvpid. 

 I have been nnable to obtain the determination of the following species. 



Platypus ? sp. 



Habitat. — -Lower Burma. 



Tree Attacked. — Pyinkadu {Xylia dolahvifonnis). Tharrawaddy, Salween 

 River, Tenasserim. 



Beetle. — Black, pointed posteriorly. 



The beetle tunnels directly down into the wood of the tree, the tunnel 



curving a little after it has entered the sapwood. The 



Life History. eggs are laid at the bottom of the tunnel, which is 



several inches in length. I took a dead mother-beetle 



in the egg-tunnel in a large girdled tree in Tharrawaddy in January 1905, 



and others mature and just issuing (the first beetles of the year) in trees at 



Kamamaung, on the Salween River, in Tenasserim, the first fortnight in the 



following March. The beetle only oviposits in fresh sappy timber. 



Hectarthrum heros, Fabr. (pp. 116 and 166). — This beetle is predaceous 

 upon the platypid found in the pyinkadu-tree. It was taken in some 

 numbers in the mature state on 8 March igo8 in company with the Platypus.
