LIFE-HISTORIES OF AUSTRALIAN COLEOPTERA. 

 Part III. 



By Walter W. Froggatt. 



This paper contains my contribution to the study of the 

 habits of our Coleoptera for the season 1894-5, and is really a 

 continuation of previous notes on this subject; for the observa- 

 tions of one year run into the next, and some of the insects have 

 to be watched for over twelve months before the larva can be 

 correlated with the perfect insect. 



As before, I am indebted to the Rev. Thos. Blackburn for the 

 determination of some of my beetles, and to Mr. R. T. Baker for 

 the verification of the botanical names of some of their food 

 plants. 



Aphanasium australe, Boisd. 



Larva short and stout, pale yellow, with well-defined abdominal 

 segments; jaws black, and truncated at the tips, mouth parts 

 raised upon a slightly lobed projection, the basal portion of the 

 head forming an encircling fold, slightly overhanging in front; on 

 the lower edge of the forehead are four irregular yellow patches; 

 thoracic segments narrow, legs small, short, ferruginous; on the 

 dorsal surface the first five segments flattened, of regular size, 

 produced into an elongate oval, slightly impressed in the centre, 

 with a patch of reddish-brown hairs on either side, 6th and 7th 

 rather larger and rounder, Sth small, 9th also short, terminating 

 in a short obtuse point; on the ^ventral side the segments are 

 comparatively flat. 



The larvae feed upon the stems of Hakea acicularis, growing 

 in the neighbourhood of Sydney, a number always boring into the 

 shrub at one place, causing the branches to wither and snaj) off- 

 perhaps nearly a dozen grubs will feed in a single branch gnawing
