Provisional Notes on the Javanese Mango Weevil, C. grains.

Abstract

The collections of the " Instituut voor Plantenziekten, " Buitenzorg, contain weevils supposed to be Cryptorrhynchus mangiferae, F., a species found in Madras [R.A.E., A, xv, 357], but some weevils taken on mango at Buitenzorg have proved to be C. gravis, F. Both species occur in the Federated Malay States; in the Philippines and Ceylon only C. mangiferae is found. C. gravis has been recorded from Bengal. The species taken at Buitenzorg is at least biologically different from that in Madras, the latter almost always boring in the stone, whereas the former develops in the flesh of the fruit and eats only the fibrous laver of the stone.
