320 FAMILY CERAMBYCIDAE 



" I cannot make out where the eggs are laid. Beetles appear in 

 September, and apparently the eggs are laid at the end of the 

 month. 



" Larval stage — at least two years. Pupal stage — about six weeks. 



" Larvae in wood in my house " (Mr. Watson cut some large 

 sections of trees containing larvae, and kept them in his house under 

 observation) " pupated about end of July or beginning of August, 

 and beetles were found beginning to middle of September. 



" Larvae pupate at end of tunnel, stopping up the tunnel with 

 sawdust, more or less cemented together apparently with saliva. 



" The larvae make a distinct noise when tunnelling, and eject 

 large quantities of sawdust. 



" The larva moves apparently up and down its tunnels, which 

 are elliptical in shape, and fully i^ in. by | in. in section " (cf. 

 fig. 217). 



" Mature beetles seem to skulk a lot in the old tunnels." 



In reporting this insect, Mr. Watson wTote : — 



" I am sending you a specimen of a beetle larva that appears to 

 do a lot of tunnelling in green oak wood in Taunggyi. When inspect- 

 ing newly erected posts round the fuel reserve 

 Damage Committed j j noticed one oak post (from a freshly felled 



in the Forest. ' , , , , ■ vu r i • u 



green tree) to have several holes in it trom which 



sawdust was being ejected, and had part of the post cut off and 

 brought to me. In it were three of these larvae. The two others are 

 still living in the piece of wood. They have now been in my house 

 some three and a half months, and as yet show no signs of pupating." 



This note was written on 14 November 1907. The observations were 

 carried on up to the middle of June 1909, with the excellent results detailed 

 above.
