On the pupa of Allotopus Rosenbergii (Voll.) (Coleoptera: Lucanidae)

Some weeks ago I received from Mr. J. D. Pasteur at Batavia the pupa of the male (forma maxima) of the above quoted interesting stag-beetle, which I thought worthy to be figured in the »Notes”. I received the specimen with the following annotation: »The pupa of Allotopus Rosenbengii (Voll.) I send herewith to you was found by me at Toegoe (West Java) in the mouldered trunk of a long since unrooted forest-tree, which in Western Java is called »Kajoe Pasang.” According to Mr. Wigman, Horticulturist of the Botanical Gardens at Buitenzorg, Kajoe Pasang is the collective name for the different species of Javanese oaks Quercus).”
