RECORDS OP TIIE AUSTRALIAN MUSEUM. 
LARVA AND PUPA OF BATOCERA WALL AG El, THOMS. 
By W. J. Rainbow, F.L.S., Entomologist. 
A short time ago, the Trustees of the Australian Museum were 
presented with a small collection of Insects from Samarai, or 
Dinner Island, British New Guinea. These had been gathered 
from time to time by the donor, the Rev. C. W. Abel, in the field 
of his labours, and amongst them were included larval and pupal 
forms of that huge Longicorn, Batocera wallacei , Thoms. 
• In respect of the former, which is apparently nearly fully grown 
a brief description may be interesting. The animal is nearly four 
inches long, footless, gradually tapering posteriorly, as is most 
frequently the case with Longicorn larvae ; the head is short, broad, 
flat, corneous, punctate, black, and provided with short, strong, 
incurved mandibles ; the pro-thoracic segment is much larger than 
those succeeding, and of a glossy mahogany-brown hue, the anterior, 
posterior and lateral angles, both above and below, are dirty 
yellowish-brown, and rough ; the other segments are fleshy, 
yellowish, and all, with the exception of the two last, provided 
both above and below, with large, rough, transversely oval, granu- 
lated patches ; these are, of course, the organs of locomotion. 
The pupa is large, soft, and of a greenish hue, with yellowish 
dorsal and lateral patches ; in other respects it presents the usual 
appearance of Longieorns at this stage of their existence. The 
wings and legs are folded against the sides, and the feet doubled 
under; the enormous antennse are turned back against the sides of 
the body, the third and succeeding joints being coiled round and 
round, something like the mainspring of a watch. 
The .adult insect is so well known, that there is no need to 
to describe* it here.
