Xg The Cane Grubs of Australia. 



A further food-plant must be recorded ; on 21st January, a number 

 of beetles were found feeding on the tender foliage of young bloodwoods ; 

 a fire had previously spread through this locality, and the beetles were 

 no doubt attracted by the extreme tenderness of the young leaves, as 

 ordinarily this is not a food-plant. 



CALLOODES PUNCTULATUS Oil. 



The adults of this species are not imcommon in the jungles of the 

 Cairns district. One food-plant only is known, a shrub or small tree 

 with dark green rough leaves ; large numbers of the beetles collect on one 

 tree and quickly defoliate it; they remain on the upper surface of the 

 leaves in the day time, and a sharp jar causes them to fall to the ground. 



On November 25th, eighteen males, thirteen females, were placed in 

 a cage for breeding purposes ; from these eighty-eight eggs were obtained, 

 which produced seventy-two larvae ; the young larvi^ were placed in damp 

 sifted soil in a flower-pot, but all died within a month. 



No. 653. 



A single supposed Stage II. larva of this species was found in a 

 collection from roots of native grasses, rich black loam soil, Cooktown, 

 9th March, 1914. 



No. 625. 



A single larva from under roots of Imperata grass, black loam soil, 

 foot of Mount Pyramid, Gordonvale. This is the sole record. 



CETONID Sp. No. 46. 



A single larva in Stage III. was obtained by digging in an alluvial 

 sandy rubbish heap, banks of Mulgrave River, IGth November, 1914; it 

 had pupated in an earthen cocoon by December .3rd. A second Stage III. 

 larva Avas found in a similar situation, 17th September, 1915. This 

 species has a peculiar method of locomotion ; only with great difficulty 

 can it travel on its venter on a flat surface, but turning on its back it 

 moves with freedom and even rapidity by quick contortions of the body. 



CACACHROA DECORTICATA Macleay. 



Stage I. has been found on January 18th, INIarch 15th; Stage II. on 

 January 18th, February 2,3rd, March 1st, 5th, April 27th ; Stage III. as 

 early as February 1st, and not again until IMarch 4th, the latest on 

 November 6th. 



The larvae were found almost e(|ually in volcanic and loam soils; 

 the records from canefields and forest and fallow lands are — 77,545 yards 

 plough furroAvs, forest and fallow lands yielded 59 larva?; 412,285 yards 

 plough furrows, canefields yielded 64 larvii?; or proportionately nearly 

 80 per cent, from the forest and fallow lands. 



Larva in their pupating cocoons have been seen as early as May 21st, 

 but they had not pupated by August 24th.
