28 The Cane Grubs of Australia. 



volcanic canefield, (yctober 28rd, 1914, parasite pupated between Janu- 

 ary 7th, 21st, emerged February 1st; host from red volcanic canefield, 

 October 27th, parasite pupated between October 28th and November 

 14th, emerged November 24th, 1914 ; pupated between January 11th and 

 20th, emerged January 27th, 1916. 



Dasygnathns pupates by the end of August, and these records are 

 all of larva3 that have been hindered from pupating by the presence of 

 the parasite. 



DEXIID Sp. D. No. 33. 



A beautiful brilliant light green species, the bead yellow, the 

 abdomen with two or three black bands. The following records : — Adult 

 taken on floor of laboratory, 17th December; adult caught at light, 

 September 10th; one reared from Stage III. Anomala anstralasice found 

 in dark volcanic fallow field, March 26th, formed puparium between 

 April 9th and 16th, emerged May 6tli; reared from Stage III. Horonotiis 

 optatus from sand in river bed, December 14th. An empty puparium 

 found in a breeding cage containing Stage III. Iloronotus optatus, 

 December 19th, is possibly referable to this species. 



D. No. 4, No. 23, No. 42, No. 47, No. 33, are typical looking Dexlids 

 probably belonging to Futilia or an allied genus. 



DEXIID Sp. D. No. 15. 



A rather small greyish species with long slender legs, possibly 

 belonging to the genus Myocera : it has been reared on one occasion, one 

 being bred from Stage III. Eaplonycha sp. No, .587, October 20th, 1914. 



DEXIID Sp. D. No. 32. 



A closely allied species to the foregoing, and a parasite of Anomala 

 australasim larvae. Of 29 larva^ placed in confinement in the latter half 

 of 1914, 11 died naturally, 7 pupated, and 11 were killed by this parasite : 

 of 11 larvffi confined in 1915, 7 pupated, 3 died naturally, and 1 was 

 killed by this parasite ; the percentage of parasitism would therefore 

 appear to be great. Puparia have been found in confinement on Novem- 

 ber 26th, December 3rd, 8th, 10th, Januarj^ 20th, and emergence occurred 

 from early in December to early in February. An adult was caught on 

 window of laboratory September 14th. Adults of this or an allied species 

 have been noticed on tree-trunks in the forest. 



DEXIID Sp. Unknown. 



The following records of puparia that were not reared are probably 

 referable to either D. No. 4 or D. No. 23, possibly to both: — (1) From 

 Stage III. Dasygnathns taken from dark loam canefield November 10th, 

 puparium found December 23rd, 1914; (2) from Stage III. Dasygnathus 

 confined in rearing cage May 26th, a larva and puparium of parasite 

 found December 8th, 1915; (3) a puparium found i)i dark loam canefield 

 February 19th, 1915, prevalent larva? being Dasygnathus Stage III. 

 mostly, Anoplognatlius Stage III., L. frcnchi Stage 111., L. alholiirta 

 Stage II. and III.; (4) from Stage III. Dasygnathns found in sandy 

 loam February 19th, 1915, puparium found February 26th; (5) from
