The Cane Grubs of Australia. 57 
Gum (Eucalyptus platyphylla), and usually on trees not more than 
20 feet high, grown examples being occasionally attacked. They are 
voracious feeders, and quickly defoliate the young trees, numbers congre- 
gating on one. During the day they remain clinging to the leaves of 
the food-plant, and pairs are not uncommon. A sharp jerk to the feed- 
ing-tree causes the beetles to drop, when they bury themselves under any 
débris present; sometimes they fly. On one or two oceasions, individuals 
have been observed flying strongly during the day, but the species is 
nocturnal in its habits. 
The only other food-plant known is the Blue Gum (Eucalyptus 
teretifolia). This is a very rare tree around Gordonvale. Several of 
these trees were noticed on January 12, 1914, on the banks of the 
Mulgrave River, greatly damaged by adults of Anoplognathus boisdu- 
valu. The trees were of considerable size (30-50 feet high) and the 
beetles were in large numbers. 
Odd adults have been taken at lights.
