36 The Cane Grubs of Australia. 
THE LARVA. 
At Gordonvale, the stages of the larva have been found on the 
following dates :— 
Stage I. Stage II. Stage IIT. 
March 21 January 28 January 20, 23 
April 7, 8, 23 | February 5 February 5, 15, 24 
June 12 | March 9, 28 March 3, 9, 10, 11, 19

May 2, 11, 13, 25, 26 June 4, 7, 8, 12, 25, 26 
June 7, 8, 12, 15, 28 July 7, 8, 16, 22 
July 5, 7, 11, 22, 30 August 8, 14, 19 
August 8, 13, 17, 21, 26 September 3

«October 28, 23 November 3, 13, 16, 18, 25 
November 16, 18 December 4, 20, 22, 24 
December 15, 24 
At Babinda, Stages II. and III. have been found January 27; at 
Mossman, III. on October 31, March 21; Cooktown, I. February 2, 28; 
Il. February 8, March 1; III. February 28. 
Thus Stage I. is found from end of January to June (probably 
an odd specimen April, therefore being limit of stage), Stages II. and 
Ill. throughout the year. There is abundant proof that this species, 
unlike albohirta, has a life-cycle of more than one year, as Stages II. 
and ff. can be found throughout the year. Thus 25 Stage IT. were taken 
from ecanefields May 14, 1913, and kept in captivity; on October 23, 22 
were alive, still in Stage II.; by November 18, two had entered into 
Stage III.; by December 17, more were in Stage III., but majority still 
in IJ.; on January 28, 1914, majority in Stage III., a few in II.; not 
again examined till July 22, when two III. were found. 
DISTRIBUTION IN REGARD TO SOILS. 
Owing to the comparative paucity of this species, there is less data 
to show its abundance in different soils. The following table summarises 
some of the data:—

Cooktown to Cairns. It is found in both forest and jungle soils, in
