The Sinoxylon beetles had attackedthem near the foot of the trunk, and had penetrated down into the base ofthe root a foot or two below the surface of the soil. The Alindria beetlestaken were mostly mature, whilst the bulk of the Sinoxylon were in the pupaor immature-beetle stage, with a few mature beetles. A few Alindria larvae were taken, and these feed predaceously upon theSinoxylon grubs. I have not ascertained whetherthe A lindria beetles feed upon the mature Sinoxylonones, but they attack the immature beetles. Melambia sp. prox. memnonia, Pascoe (p. 115)..—The Melambia beetles are of stouter build than the Alindria,and easily distinguished by the anterior outer angles of theprothorax, which is broader than long, being produced forward,the anterior margin being sunk between them ; the elytra arebroader behind, thickset, bluntly round
