“NOTES ON PARASITIC WASPS. 
(By L. Gallard.) 
These notes were illustrated by exhibits of the speci- 
mens described. E ; 
ZHUZERA—The larval skin of a very large moth of 
this genus. Contained considerably over 100 parasitic 
wasp cocoons, so closely packed as to resemble a series of 
long honeycomb cells. So closely packed were the cocoons 
that the perfect shape of the host grub was retained. This 
specimen was found in the centre of a Blue Gum sapling 
, 
near Gosford. 
Cur-Worm ‘‘Busona Morn.’’—In this case about 150 
small wasps emerged. The caterpillar when taken from 
‘the ground retained its normal shape, but was quite 
flabby, so that it hung down on either side when laid 
across a stick. By the following morning all the wasps 
had emerged and arranged themselves around the cater- 
pillar’s skin, so that only the ends could be seen. ~ 
Papmio Arceus—From the pupa of this butterfly 
175 black chalcid wasps emerged through a small hole in, 
the side. ati 
Brown Outve Scate (Lecaniwm oleae).—About three 
dozen peyasitie wasps (Scutellista cyanea) were bred from 
this scale, taken from the Passion Vine at Eastwood in 
January, 1916. This wasp was introduced from Cali- 
fornia, about 17 years ago, as a parasite of the Brown 
Olive Seale. About two-thirds of the scale from Ryde and - 
' district were found to be parasiticised. The wasp can be 
readily identified by the very black colour, the hump- 
shaped back, and the peculiar V-shaped scutellum on {titer = * 
thorax. After devouring the inside of the scale the larvee 
pupate in the dead shell, and duly emerge through the 
opening on top. ;
