 Tenasserim. 



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 

 FlG. 138. Larva of lobes slightly produced, base bisinuate, with median 

 Chrysobothrts lobe much produced, as are posterior angles. Elytra 

 with apical portions separately rounded, a longi- 

 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 

 lower 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, 5mm. 



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 Terminalia 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 gallery 

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

 from end to end without the curves. The larv;i. when 



full-grown, eats out a pup;d
