attempt is ready the far superior work supersedes the 
necessity for it; but, having prepared it, I give it as it 
stands without alteration, save that, availing myself of 
Prof. Riley’s courtesy, I have given a short account from 
his observations which he has placed in my hands of the 
male insect; and I feel in recommending all readers 
to procure and study Prof. Riley’s paper, that at least one 
powerful “ method of prevention ” is placed before them, 
which, if duly used, will bring about a most beneficial 
lessening in amount of this hurtful pest, well known as 
“ The Scourge of South Africa.” 
Means of Prevention of Increase. 
Insect Enemies. 
The carnivorous larva or maggot of a species of Chry - 
sopa or Lace-winged Fly, or “ Golden Eye,” and also the 
grubs of a Coccinellid or Ladybird, have been observed by 
Mr. Bairstow to do much good by destroying the young 
Australian Bugs, just at hatching time, within the sac of 
the female. 
Of these Mr. Bairstow says :—“ The Coccinellci is by 
far our best friend. It is proving a perfect god-send in 
destroying the perfected young in nidus of the female 
* bug.’ The larva buries itself in the gravid female and 
completely destroys her progeny, the dead carcase falling 
to the ground; and it eats the ‘ bug ’ not only when it is 
young, but when it (the Coccinellci ) has developed to 
beetle condition. I have taken as many as five or six 
young hugs out of the inside of one of these Coccinellcc 
or Ladybird Beetles. The changes from grub to beetle 
are rapidly passed through, as with other CoccinelliclcsC 
Its efficacy cannot be over-estimated, and an importa¬ 
tion of the Coccinellce to infested regions would be certain 
to be of service.—S. D. B. 
This species of South African Coccinellid is of the 
size and shape figured, and may be generally described as 
black, with a blood-red spot in the centre at the base of 
the wing-cases, and clothed with thick short down above; 
the under side and legs reddish, and also downy.
