Beetle. — Slightly dull coppery-bronze. Three 



highly punctate coppery-red or yellow depressions on 



each elytron. Under-surface 



Description. brilliant green ; legs, sides, 



and last abdominal segment 



coppery. Head with a well-marked transverse 



carina between the eyes. Sides of prothorax concave 



just above the middle, anterior and posterior angles 



oblique, anterior margin slightly sinuous, median

tudinal depression at shoulder, and a well-marked 



costa running parallel to suture in apical half, a less 



well-marked one parallel to constricted edge in apical third, meeting the 



sutural one at apex, and a third, broken, in the angle between these 



two ; the three circular depressions are placed longitudinally and 



medianly on each elytron; (i) just above base, (2) in basal half, (3) in 



louver part of apical third. Last abdominal segment carinate down 



middle, and furnished with two terminal sharp spines ; anterior femora 



unidentate. Length, 12.5 mm. ; breadth, 5 mm.

The beetle appears on the wing in Tenasserim some 

 time during December or January, and 

 Life History. lays its eggs in crevices in the bark of 

 green sickly Tcrminalia toinentosa trees or 

 in newly felled ones. The larva, on hatching out, feeds upon 

 the bast layer at first, and then goes into the sapwood, 

 remaining in the outer layers, where it eats out a flat, wind- 

 ing, shallow gallery in the wood. This gallery is packed 

 with the wood-dust and excreta of the feeding grub. 

 The larval gallery varies greatly in direction ; it is usually 

 carried more or less parallel to the long axis of the tree, but 

 it may bend to right or left for no apparent cause. From 

 the appearance and size of the gallery it would appear 

 that the larva increases rapidly in size after first hatching 

 out, and more slowly at later stages. The larval galler}- 

 shown in fig. 140 is almost seven inches in a straight line 

 from end to end without the curves. The larva, when 



full-grown, eats out a pupal 

 chamber by boring down into 

 the wood at a sharp angle, 

 the chamber so eaten out 

 being about an inch in length 

 (cf. fig. 140), rather broad, and 

 oval in shape. This chamber 

 is quite free from the wood 

 excreta and dust with which
