Illtngworth (J. F.). Investigation of Control Measures for White 

 Grubs affecting Sugar Cane in Queensland. — Jl. Econ. Entom., 

 Concord, N. H., xii, no. 6, December 1919, pp. 451-455. 



Tremendous losses are sustained in the sugar-cane growing districts 

 of Queensland owing to the ravages of white grubs [Lepidiota sp.]. 

 Two years' investigation shows that the most important remedial 

 measures consist in stimulating the vigour of the plant, destroying 

 the eggs by cultivation, application of poison and removal of feeding 

 trees. [R.A.E., A., vi, 526 ; vii, 200, 411 ; viii, 02.]

 December 1919, pp. 455-457, 1 plate. 



During observations on the breeding of Campsomeris tasmaniensis 

 and C.formosus under laboratory conditions it was noticed that when 

 several white grubs [Lepidiota] were placed in the jar with these 

 wasps they were all immediately paralysed by them, although 

 eggs were never deposited on more than one individual. The 

 method of breeding the parasites is discussed. [R.A.E., A. vi, 495.]

In certain districts in Queensland the sugar-cane beetle borer, 

 Rhabdocnemis obscura, is no longer a serious pest owing to the 

 estabUshment of its Tachinid parasite, Ceromasia sphenopliori, which 

 is responsible for the destruction of about 90 per cent, of the grubs 

 [R.A.E., A, vii, 167]. Attempts are being made to extend the 

 distribution of this parasite over a wider area.

 Disease of Red Clover in the North Western States. — Jl. Econ. 

 Entom., Concord, N. H., xii, no. 6, December 1919, pp. 460-462. 



Tylenchus dipsaci, Kiihn {devastatrix,Kuhn) has been found to be 

 the cause of severe losses amongst red clover in Idaho. At present 

 red clover is the chief food-plant of this Nematode and it has only 

 occasionally been recorded on alsike and white clover. The limited
