54 The Cane Grubs of Australia. 
DISTRIBUTION IN REGARD TO SOILS. 
Of our total number of larve of this species from Gordonvale of 
which record was kept concerning the soils, they are distributed as 
follows :— 
Red Volcanic. Clay and Black Loam. Sandy Loam, 
84 ae 805 os 841 
But of the middle column 643 were collected from one field. Thus the 
larvee are commonest around Gordonvale, in the mixed sandy and loamy 
soils (not sand), near the Mulgrave River. 
The following records show more truly the relative abundance in 
red voleanic and clay or black-loam soils:—60,700 yards of plough 
furrows, red voleanic soil, yielded 45 larve; 38,350 yards of plough 
furrows, clay and black loam, yielded 42 larve; = -000757 and -001095 
larve per yard respectively. 
DISTRIBUTION AS REGARDS HABITAT. 
The larva of this species has been found by us in various districts 
throughont coastal Queensland, as far as the Clarence River in New 
South Wales. It is very common around Gordonvale, where it has been 
found in various situations—namely, in upland and lowland, voleanie¢ 
and clay or black ioam, forest, various grasses, and canefields; in natural 
jungle, beneath logs, &., beneath heaps of decayed cane; in sandy loam, 
near the river; under native grasses in forest on coast range, 800 ft. 
Of our total number of larve from Gordonvale of which record was 
kept concerning the habitat, they are distributed as follows :— 
Canefields, Forest, Grasses, Corn, Rubbish, Decayed Cane, Dead 
G i ane. qi x 2 Vegetable Matter, with no 
rowing Cane Fallow Land. Living Vegetation. 
873 99 826 
But of those from cane 643 were collected in one field. 
The following records show the relative number of grubs from 
eanefields as opposed to fallow jand, grasses, forest or corn lands :— 
65,000 yards of plough furrows, canefields, yielded 90 larve; 35,000 
yards of plough furrows, forest, grasses, &c., 19 larve; or -001385 and 
-00057 grubs per yard respectively. Upland and lowland soils are both 
infested, but our data are not sufficient to show the relative proportions. 
THE PUPA. 
LENGTH OF PUPAL STAGE. 
Our data do not allow us to give the length of the pupal stage, 
Probably it is similar to allied species.
