16 The Cane Grubs of Australia. 



LEPIDIOTA Sp. No. 10. 



These are the supposed Stage I. larvje of alhohirta from soil near 

 roots of cane, Finehhatton, Maekay, 17th October, 1911, mentioned in 

 Bulletin No. 2', p. 21, with a footnote calling attention to its being a 

 distinct species. 



LEPIDIOTA CAUDATA Blackburn. 



The Larva. 



Common in the jungle canefields in the Babinda Mill area, where it 

 is probably as plentiful as olholiirta, and no doubt causes as much 

 damage, but very little data relating to the species have been gathered. 

 The Stage II. and III. larvte from Babinda, mentioned in Bulletin No. 2, 

 p. 36, as frencM, were this species. 



The stages have been found on the following dates: — Stage II., 

 January 27th, September 28th; Stage III., January 28th, September 

 10th, 27th, October 12th. Like frenchi, Stages II. and III. are found 

 throughout the year, and the species has a two-year life cycle. Stage III. 

 larvaj found on September 28th had recently moulted from Stage II. 



The species is without doubt a native of the .jungle lands. Digging 

 cane-holes in yellow clay loam, recently cleared jungle, produced Stage 

 III. larva.^ in their second year of development and pupa% on September 

 28tli ; thus the land was uncleared at the time of egg-laying and for twelve 

 months afterwards. The records from the Babinda district are all from 

 yellow clay loam, but no collecting has been made in other soils. The 

 species has also been taken in cultivated and garden fields not uncom- 

 monly at Kuranda. 



The Pupa. 



Pupffi have been obtained on the following dates : — September 10th, 

 28th, October 12th, November 16th, in natural habitats at a depth of not 

 more than six inches. 



The Adult. 



A cage containing Stage III. larvje placed there on February 11th, 

 when opened on the 15th September, contained freshly-emerged adults. 

 Beetles have been noted on the wing on the following dates : — September 

 10th, 29th, October 10th, 12th, December 5th. The September records 

 are early and few emerge in that month ; thousands emerged on October 

 10th; and on December 5th a number were observed swarming and 

 mating, evidently a fresh emergence. Nothing is known as to the habits 

 of the adults, but the species appears to feed on the foliage of jungle 

 trees at night and to hide in the day. 



The unemerged adult has a distinct bluish gloss on the elytra. 



ANOPLOGNATHUS Sp. Wo. 686. 



The Larva. 



Found in the jungle cane-lands of the Babinda Mill area where it is 

 by no means common. Stage III. larva' have been obtained on the 

 following dates :— September 10th, 21st, 28th, October 12th, all from 

 yellow clay loam. A Stage III. larva found on September 28th had
