Distribution. 
Localities :—Sikkim ; Burma ; Singapore ; Java ; Nias ; Ceram ; 
British New Guinea ; Trobriand Is. 
The distribution of D. ceramicus in Burma recorded in the following 
pages is based on information supplied by forest officers and timber 
lessees from 1913 onwards, but mainly in reply to circulars issued in 
1913 and 1919. As considerable diversity of opinion exists about the 
occurrence and the conditions governing the local abundance of the 
pest, and apparent contradiction is not infrequent, I have thought it 
desirable to reproduce the information verbatim in many cases. An 
attempt is made later to interpret these opinions in the light of the data 
supplied by the 1918-19 analyses. The authority for the record 
quoted is given in square brackets at the close of the sentence or 
paragraph [See footnote below.] 
Northern Circle. 
None of the moister forests are free from the borer [R. F. A., 1908-09, p. 52.] 
1. Myitkyina. 
The beehole borer as a serious pest is confined to the Indawgyi 
valley, being much less abundant in the Namyin and Kaukkwe 
drainages and scarcely occurring at all in the forests along the 
Irrawaddy ; in the Taungbalaung Reserve in the Upper Defile the borer 
is practically absent; the Kyunsalai plantations in the Nammun 
Reserve, Indawgyi are badly attacked. Timber from lowlying forest 
is worse attacked than that from hillsides, possibly influenced by the 
fact that nearly all the flat forest consists of almost pure teak, while 
mixed or semi-evergreen forest with scattered teak prevails on 
hillsides. [D. F. 0., Feb. 1914]. The rainfall in the Myitkyina 
division varies from 76 to 108 inches.
