The Cane Grubs of Australia. aH 
eanefields or under native and other grasses, and is seemingly more 
abundant there than in canefields. Of a total number of 390 larve of 
which record was kept concerning the habitat, they are distributed as 
follows :— 
Cane fields, Forest Grasses, Weeds, &e. 
257 a 133 
But of those collected in canefields, 114 were taken in one collection. 
Moreover, much more collecting has been made in the eanefields than in 
the open. 
DISTRIBUTION IN UPLAND AND LOWLAND. 
Of the total number of larvee in general collections from Upland 
and Lowland, they are distributed as follows :— 
Lowland. Upland. 
81 os 22 
Owing, however, to the small number of larve, this result is probably 
not true. 
EE Peas 
We have very little data as to the pupation of this species. 
Numerous larve were found in earthen cells in grass lands at depths 
varying from 2 to 31% feet, but usually nearer the lesser depth, in the 
second week of June. A pupa taken from a bred cage on November 20 
emerged December 10; another from a bred cage on November 25 
emerged December 12. 
EMERGENCE OF ADULTS. 
The only dates on which this species has been recorded are—January 
22nd, 1912, December 3rd, 10th, 12th, 1912 (bred), February 3rd, 1913, 
March 13th, 1913, December 20th, 23rd, 1913. 
From several grass-plots in the township of Gordonvale, thousands 
have emerged in the three seasons noted. Emergence takes place soon 
after dusk, and continues for about half an hour, the emerged beetles 
circling round low over the surface of the ground, and mating 
immediately. A walk round one of these plots just after dusk has 
produced numerous mating pairs, clinging to wire or wooden fences or 
sides of houses, &e.. No food-plants are recorded, but one specimen has 
been taken from many, on the foliage of bloodwood (Hucalyptus corym- 
bosa ?), and several of the forest trees probably constitute the number. 
LEPIDIOTA Sp. No. 666. 
LARVA. 
Known only from the Bundaberg and Childers districts, South 
Queensland, the specimens having been obtained solely from canefields. 
The Childers specimens, several Stage IIl., two Stage II, were taken 
by following plough, red volcanic soil, upland, July 1. Those from 
Bundaberg, three Stage III, were taken from under stool of cane, 
March 9. 
LEPIDIOTA Sp. No. 45. 
We have only one record of this species, several larve stage III. 
being obtained from a canefield cleared from jungle only six months,
