FAMILY CERAMBYCIDAE 317 



state of affairs as existing in 1905 is entirely a thing of the past, the beetle 

 being now almost scarce in the station, whereas it existed in thousands in 

 the year mentioned. 



If infested timber is converted into firewood, the fuel must be utilized 

 during the winter of its conversion. If allowed to remain in store during the 

 following spring mature beetles will issue from it and carry on the attack. 



./Eolesthes sp. prox. aurifaber, White. 



REFERENCE. Ind. Forester, xxxiv, 216. 



When investigating the attacks of what was known throughout Burma 

 as the " Bee-hole Borer of Teak ' in the Mohnyin Forest in Katha the 

 Deputy Ranger and myself took a large number of longicorn larvae from 

 a green teak-tree which had been attacked by the Bee-hole borer (Duomitus 

 ceramicus). The grubs I noted resembled either sEolesthes, Ploccederus, or 

 Hoploccrambyx ones. They were feeding in the bast and sapwood in con- 

 siderable numbers. Some had already bored down deeper into the wood to 

 pupate. This was on 24 February 1905. I could find no pupae or 

 mature beetles. 



Mr. T. A. Hauxwell, Conservator of Forests, Pegu Circle, took, in 1908, 

 a specimen of a longicorn beetle issuing from a hole in a teak log which 

 was being squared in a Rangoon mill. This log was found to be badly 

 bored. The insect was dispatched to Mr. C. J. Gahan at the British 

 Museum, and by him identified as a species of Eolesthes closely related to 

 aurifaber, but whether distinct or not it was impossible to say without a 

 specimen of the female insect. 



Teak is, as is shown in this chapter, tunnelled into by several 

 longicorn beetles, but the work of a longicorn larva is very easily dis- 

 tinguishable from that of the caterpillar of a moth. There is of course no 

 connexion or similarity between these tunnels of the Cerambycidae in teak 

 and those of the true " Bee-hole borer " Duomitus ceramicus, the author of 

 the " bee-holes " in teak logs which have been known for well over a 

 century.* 



MASSICUS. 



Little is known upon the importance of this genus in the forest. The 

 credit for observations so far carried out belongs to Mr. H. W. A. Watson,
