Some two years ago I received from Rev. L. C. Biggs, H.B.M. Chaplain at Penang, a parcel of insects collected by Mr. F. G. Durnford in Sungei-Ujong. Among them was a speciment the envelope containing which was labelled Charaxes Durnfordi, n. sp. Mr.Biggs, in sending the lot, called attention to this particular specimen in his note, saying: “It looks as if it were covered with mildew, which Durnford assures me is really fluff detached at the time of its capture.” I did not examine the specimen ver particularly at the time of its receipt, except to note that it was covered with a whitish mealy deposit, particularly thick upon the abdomen, and that it was not a Charaxes.
