214 FAMILY BUPRESTIDAE 



I cut out a dead specimen of this buprestid from its pupating-chamber 

 in the wood of a dying sissu-tree in the Changa Manga Plantation on 

 17 May 1905. The insect is new to science, and I take pleasure in naming 

 it after that eminent entomologist, Mr. Guy A. K. Marshall. The grub 

 eats out an elongate winding gallery entirely in the cambium layer, only 

 boring into the sapwood to pupate. 



Sub-family CHRYSOBOTHRINAE. 



Front of head constricted at insertion of antennae ; antennae bent, 

 third joint very elongate ; poriferous pits variable ; eyes oblique, placed 

 close together on vertex. 



This sub-family contains the large genus Chrysobothris, of which there 

 are a considerable number of Indian species. The sub-family contains two 

 species known to infest forest trees. It is probable that a number of the 

 other known species will be found to oviposit in trees. 



Chrysobothris. 



A large genus with numerous species in India, some of which may 

 prove to be of importance in the forest. The elytra often have circular 

 depressions on them of a different colour from the rest of the surface. 



Chrysobothris musae, Thery.

Habitat. — Ceylon . 



Tree Attacked. — ? Plantain (Musa sapientum). Hovonapotani, Ceylon. 



Beetle.— Oblong-oval, sub-parallel, but slightly convex. Front of head dull red, brilliant 

 behind the eyes and on vertex ; prothorax bluish black, edged anteriorly with red ; elytra 



olive-green, with four lighter-coloured impressions ; under-surface 

 Description. green medianly ; posterior tibiae and tarsi blue. The prothorax is 



furrowed behind the anterior margin, the latter nearly straight, 

 anterior angles acute, sides sinuate in middle, posterior angles rounded, base bisinuate, the 

 median lobe slightly truncate. Scutellum small. Elytra with the four impressions arranged as 

 follows : (i) on the basal lobe ; (2) smaller, behind the humeral calus ; (3) in centre of disk ; 

 (4) placed nearer the margin in the apical fourth ; a raised costa parallel to suture, a second 

 meeting first at base and ending in apical fourth. Length, 10 mm. ; breadth, 4 mm. 



This beetle has been reported as taken on plantain-trees in Ceylon.
