30 The Cane Grubs of Australia. 



ASILID Sp. D. 48. 



A rather small species; the adult is somewhat yellowish, the legs 

 wholly yellow. A number of larvae was taken from red volcanic soil 

 badly infested with cane-grubs, July 7th ; threie pupated between 

 November 29th and December 14th, two emerged on December 23rd, 

 the third on December 26th. An adult was captured on leaves of sugar- 

 cane, March 27th. 



ASILID Sp. No. 1139. 



This fourth species is a long slender larva, very different from the 

 other three. One only has been found, from red volcanic fallow field, 

 May 20th ; it was kept in confinement and died on Januarj^ 2nd ; during 

 its period of confinement it killed the following larvaa: — 4 Stage II. 

 L. frenchi, 5 II. Anoplognathus, 2 III. No. 650, 1 II. and 1 III. Isodon 

 puwcticolUs. 



THE DIPTEROUS ADULT PARASITES. 



A small brown dipteron with a dark head (D. 6) has been bred 

 from LepicUota alhohirta adults. One was reared in February, 1914, 

 but the species was not again recorded until December, 1915, when a 

 number of beetles of those brought in and kept in confinement v/ere 

 killed by this fly ; in some cases one or two parasites emerged from the 

 host, but from eight to twelve was the general rule; the dead hosts when 

 handled easily fall in pieces, unlike the beetles that have died naturally : 

 the parasites pupate in the abdomen of the host. 



A common grey and black Sareophagid (D. 13) is suspected of 

 being a second adult parasite of alhohirta ; it has been reared on more 

 than one occasion, but there was no absolute certainty that the eggs had 

 not been deposited in the beetles after death.
