MEMOIRS OF THE QUEENSLAND MUSEUM. 
twelve species, or 30 per cent, of them, were new to science. The remainder have 
not yet been identified. The majority were taken on various flowering shrubs, 
the most attractive flowers being Leptospermum flavescens, Leptospermum 
scoparium, Backed virgata, and Lomatia silaifolia . 
One species of Thynnid, Ariphron petiolatus , Sin., according to my 
experience, seems to be exceptional in that it does not frequent flowers to the 
same extent as the other species. Out of twelve specimens taken during the 
season, one male was caught on the wing, one male and female were caught 
in copulation on the wing, four pairs were taken in copulation on the trunk 
of a standing dead tree, and one male only was taken on flowers. 
An interesting fact which I have observed regarding the history of these 
wasps is that a number of the small and medium-sized species are double-brooded, 
and the point may assist in throwing some light on the earlier stages of these 
insects. Thynnoturneria cerceroides, Sm., Bhcigigaster unicolor , Guer., Thyn- 
noidcs f idvipes , Guer., Lestricolhynnus sp . new, and three undetermined species 
were taken on Leptospermum flowers in September, and greatly to my surpise 
the same seven species were again captured at the end of April, a number of 
them being in copulation on flowers of Bceckca virgata , which, owing to the 
unusually wet summer, was then flowering for the second or third time. The fact 
that a number of this late brood were taken in copulation shows that they were 
newly emerged and not stragglers from the spring brood, and I am further of 
the opinion that this proves that the hosts are double-brooded also. 
Superfamily ICHNEUMONOIDEA, Family EVANIDaE. 
Megalyra Sasciipennis, Westwood. — This usually rare insect was captured 
around Brisbane in four different localities during last season. At Tambourine 
Mountain, on October 23rd, several females were taken flying round the trunk 
of a standing dead tree in a newly burnt “clearing.” Another female was 
taken on October 28th (on a fallen tree) at Morniugside, near Brisbane. On 
the occasion of a fortnight’s collecting trip on Stradbroke Island during 
December, both sexes were caught on some grey gums felled the previous year. 
At Kelvin Grove during the first week in January, a capture of both males and 
females was made on trees cut down four months previously. 
During the Stradbroke trip, being desirous of obtaining a good series of 
this curious insect, I visited the same logs every day for eight days, but did 
not see any females although the males were plentiful. On the ninth day, 
however, the females appeared, and afterwards were as numerous as the males. 
One female was observed with her ovipositor wedged so tightly in a crevice in 
the bark that there was no difficulty in catching her without the aid of a net.
