50 Fhe Cane Grubs of Australia. 
PEE EU A. 
A single one found in sand, October. Like Anoplognathus, No. 434 
and No. 576, the pupa hes enclosed in the larval skin, which is split its 
entire length down the meson of dorsum; the pupa hes with its dorsum 
against the venter of the east larval skin. It is quite possible to identify 
the species from this larval skin, which remains in perfect condition, 
and ean be handled freely if care is taken. A second pupa found in 
sand, 29th October, emerged 11th November.

EMERGENCE. 
An adult reared on October 30, from a pupa found in sand, is 
our sole reeord of the time of emergence. Beetles have been captured 
in the forest on the following dates:—February 5, 26, March 12, 16, 
Deeember 24, 1913; January 11, March 31, April 12, 16, 1914; locality, 
Gordonvale. 
Hasits, Foop-Puants, &c. 
Odd specimens are sometimes taken at light. A few have been 
found on foliage of forest trees, always singly or in pairs, never in 
numbers. The known food-plants are Melaleuca and bloodwood 
(Hucalyptus corymbosa (?)). 
LENGTH oF LIFE. 
Adults captured in the forest, and kept in cages with sifted damp 
earth, and leaves of their food-plant, have lived as follows :—

An adult reared from a pupa on November 11, and kept in confine-

NuMBER oF Haas Lan, &c. 
A single female was captured on February 13, and kept in confine- 
ment in a tumbler with sifted earth. Until February 16 no eggs had 
been laid; between then and morning of the 20th five eggs were laid; 
another egg was found at 5 p.m. the same day; at 8 a.m. 21st seventeen 
more eggs were deposited; and a final batch of five at 5 p.m. the same 
day. Thus twenty-eight eggs were laid in a period of not more than five 
days, twenty-two being deposited in twenty-four hours, or seventeen in 
lifteen hours. The beetle lived until the 26th. The eggs were laid singly 
or in clusters of two or three. A female caught at light on April 12 
contained eggs in the ovary.
