The first abdominal segment is almost square. The hypo- 

 pygium is prominent, cultriform, black. The fulvous colour on 

 the ventral surface is broader on the basal half. The oviposi- 

 tor is slightly longer than the abdomen. In the male, the 

 abdomen is black on the ventral surface. The metanotum has 

 no keel, but has a shallow furrow down the middle ; its sides 

 are bordered by a keel, which, at the apex, runs on to the 

 central part ; the metanotum is strongly aciculated and densely 

 pilose. Coxae closely, distinctly punctvired, except at the base 

 below. There is a distinct furrow down the basal three- 

 fourths of the mesosternum, ending at the apex in a fovea. 



APHIDIIN.E. 



LiPOLEXis RAP.E Curtis. 



Ashmead, Proc. Linn. Soc. N.S.Wales, 1900, 353. 



Albury, New South Wales. Bred from cabbage-aphis (W. 

 W. Froggatt ; in May). A common parasite in Australia, 

 upon the cabbage-aphis. Found in Victoria and New South 

 Wales, in most cabbage-gardens (W. W. Froggatt). 



It is, no doubt, an introduction into Australia, along with 

 its host. It is to be hojjed that it may help to reduce the 

 number of the latter, as it does in Europe and the United 

 States.

 palpi rufo-testaceous : ovipositor black, its tip naiTOwly 

 white : wings hyaline, stigma and nervures dark testaceous :
