THE AUSTRALIAN NATURALIST. 35 
species, they do not form a cocoon, but make a little cell 
in the host larval tunnel, by spinning a partition in front 
and behind, in which they develop as naked pupe. 
In 1904-5 I bred M. fasctipennis from pupx taken 
from She Apple (Angophora lanceolata) and Red 
Mahogany (Hucalyptus resinifera) trees in April. On 
October 4th, 1905, I took one on the wing. In 1910 I 
took both species from the common Black Wattle (A. 
decurrens), and in September, 1915, I got two fine speci. 
mens of M. Shuckardi out of the same plant at Epping. 
When I split the piece off the tree the adult wasps fell 
to the ground, and did not attempt to fly, being apparently 
dazed by their sudden emergence to the light. 
No. 3. Syngaster lepidus. A parasitic wasp of 
medium size, very common in ‘sandstone country. 
No. 4. An amber-coloured undermined species, of 
about the same size as No. 38. 
Weevil Parasites—No. 5. The striped Pimpla, with 
white-banded antenne (Mesostinus, sp.), bred from the 
common Orange-borer (Orthorrhinus cylindrirostris). 
No. 6. Another striped species, resembling the last, 
but having shorter elbowed antennx, and the ovipositor’ 
shorter and turned upwards. Also bred from Orange- 
borer. . 
No. 7. <A large orange-coloured wasp, about three- 
quarters of an inch in length, body fairly heavy, long 
antenne and ovipositor, and clear wings. Bred from the 
short, stout weevil of the Bangalow palm. I watched 
these thrusting their ovipositors into the tunnels of this 
weevil, and on several occasions I have taken them dead, 
with the ovipositor caught in the tunnel. 
No. 8. <A small dark orange-coloured wasp, with 
large, prominent, dark eyes, and a round abdomen. Ovi- 
positor medium, wings clear, antenne fairly long. 
No. 9. A small black metallic wasp, of the genus 
Thawmasura. Antenne elbowed, head wide, eyes prom- 
inent. Thorax stout and long, abdomen flask-shaped, taper- 
ing to a point. The dorsal surface of abdomen highly 
metallic, and the wings with large smoky blotches. The 
last two species are also parasitic on Huthyrrhinus med- 
tiabundus,
