Length, mm. to mm. ;breadth, mm. to mm. The above description, which was made at the time fromfresh beetles taken by myself in the Chittagong Hill Tracts,differs slightly from that of Gory, the differences being probablydue to his specimens being dried ones. My specimens averaged55 mm. in length and 20 mm. in breadth. So far as I am aware,this is the first report of the insect from the Indian FlG. 130.—CatoxantJia opitleiita, Hill Tracts. The grubs of this beetle feed in the bast and sapwood of, I believe,several species of trees. I have cut out beetles from Life History. the pupal chambers in the jarul (Lagerstroinia Flos-Reginae) and chikrassi (Chickrassia tabularis), and Mr. A. H. Mee, of the Bengal Provincial Forest Service, took specimensfrom other two jungle trees in the hill tracts, the names of which hedid not, unfortunately, record. Long, broad, shallow, winding galleries are eaten out by the grubs inthe bast and sapwood, the whole of the bast layer being at times riddledby them. The beetles appear on the wing in late May in the Chitta-gong Hill Tracts, at about the period of the bursting of the larvae feed in the tree either till the beginning of December, whenthey pupate, or they pass through the cold weather in the larval stage,pupating in February or March.
