SOME FIELD NOTES ON QUEENSLAND INSECTS. — HACKER. 99 
On chopping into the log several larvae and pupte of a Longicorn Beetle were 
found, which were ascertained by breeding out to be Phoracantka recurva, 
Pascoe. It is fairly certain that the female Megalyra was ovipositing in one of 
the beetle larvae when captured. 
Superfamily PEOCTOTKYPOIDEA. 
Aphanomerus ru£escens, Perkins.* — This wasp is parasitic in the eggs 
of the Homopterous insect Colgar peracuta , Walker, belonging to the family 
Fulgoridse. The host is a common insect in our fields and gardens, and lives 
upon a number of different trees and shrubs. Its egg capsules are disc-shaped, 
pale green in colour, and are firmly glued to the underside of the leaves; the 
side nearest the leaf being flat, while the outer side is convex. There are 
usually between forty and fifty eggs in each capsule. The eggs are ovate-oblong, 
with a carina at each end extending longitudinally for about one-third of the 
length. These carinas split when the eggs hatch, making elongate openings 
through which the young nymphs escape. The parasite, however, does not 
emerge through the longitudinal carina as does the rightful occupant, but eats 
a small hole in the side of the eggshell. 
There appear to be several broods of Colgar peracuta in the course of a 
year, but, judging from the few scattered observations which were made, I am 
inclined to think that the parasite only attacks eggs belonging to the winter 
brood. 
Last June and during the early part of July the parasites were observed 
in numbers on the underside of Canna leaves. A few were seen walking about 
the leaves, but the majority were in groups, quite stationary, in the immediate 
vicinity of small clusters of the Fulgorid nymphs. These nymphs were seen at 
the same time on the underside of the leaves. Towards the middle of July the 
nymphs had become adults, and the parasites had entirely disappeared. No 
more parasites were seen until June of the following year, when they again 
occurred in numbers under similar conditions. 
We are indebted to Mr. A. A. Girault for his kindness in the identification 
of the parasite. 
Order COLEOPTEEA, Family TENEBRIONIDiE. 
Byrsax macleayi, Pascoe. — In November, 1912, while collecting insects on 
Tambourine Mountain, I came across some large dead fungi of the genus 
Polyporus attached to a fallen tree. On breaking a piece it was found to contain 
several beetle larv®. These were not minutely examined at the time, but it 
was noted that they were white, shining, semi-transparent, short, stout, and 
about the size of a pea. They were scattered through the fungus, each larva
