The beetle wasfeeding on the leaves of teak, and feeding and ovipositing on those of //Hclictcrcs. The teak-leaves had their edgescut and slit up under the attacks. The softpubescent leaves of the Hclictcrcs were skele-tonized, the parenchyma of the leaf being eatenout, leaving a rough lace-work. Other leaveshad portions eaten out of the edges, or patcheseaten out of the interior, the veins being eatenas well as the parenchvma, as shown in thefigure. This latter was the common method ofattack in the case of the teak-le
