in the case under his notice, and suggested measures of 
transmittal to S. Africa of this serviceable destroyer. 
A few specimens of thq two-winged fly were sent over 
to me, but unfortunately, dither in transmittal or in pro¬ 
cess of unpacking, they were so much injured that, aftei 
submission to various of our best authonties, it has been 
found totally impossible to identify them with certainty; 
but some slight amount of information may be conveyed 
by the following rough and general description of the 
best specimen, in its dried condition 
Length about one-sixteenth of an inch ; colour dark; 
abdomen green and hairy (hairs apparently on the edges 
of the segments). Thorax cylindrical; head not quite as 
wide as the thorax, nearly straight behind, convex before, 
with large compound eyes of a reddish colour, each 
occupying about one-third of the width of the head as 
seen from above. bhe abdomen appealed somewhat 
narrowed to the extremity and bent undei the insect, but 
it was impossible to say whether this was the natuial 
position and form. 
The only perfect leg remaining had the tibia (or shank) 
widened, and the tarsus (or foot) exceedingly fine and 
slender. The neuration of the wing is conveyed in the 
figure given of the portion secured. 
The above description is useless for scientific purposes, 
from the antennae and other points needed for identifica¬ 
tion being absent, but may help in conveying some general 
idea of the appearance of the fly. 
Portion of wing of Dipterous fly (much magnified), of which the laive 
are predaceous on Icerya purcliasi at Adelaide, S. Australia.
