[October- December 
Thus in unsprayed timber we have the various insect ene- 
mies, the “wilt” or whatever the disease is, the birds devouring 
imagoes and the egg parasite. I look for a distinct betterment 
'in the outlook for 1923. 
SOME PARASITIC HYMENOPTERA FROM NEW ZEA- 
LAND. 1 
By Charles T. Brues. 
Dr. R. J. Tillyard, Chief of the Biological Department of the- 
Cawthron Institute for Scientific Research in Nelson, New 
Zealand, recently sent me a small shipment of parasitic Hvmenop- 
tera for indentification. Although the collection consists of 
only a few specimens, these are of considerable interest on ac- 
count of our almost complete ignorance of the insect fauna of' 
New Zealand belonging to these families, and I have therefore- 
taken this occasion to report upon them, although Dr. Tillyard 
has promised more extensive material in the future. 
All the species mentioned below are apterous or nearly so,, 
distributed in three families, the Ichneumonidae, Braconidae 
and Belytidae. The types are in the collections of the Cawthron 
Institute. 
Family Braconidae. 
Metaspathius gen. nov. 
$ Apterous. Head globular; antennae inserted on a frontal 
prominence, 17-jointed, scape short and thick, pedicel moniliform; 
first three flagellar joints much elongated; eyes very small, round; 
ocelli obsolete; head margined behind; clypeus excavated, leaving 
a rounded mouth opening; palpi simple; slender. Prothorax

shield-shaped; propodeum coarsely reticulated. Legs with the 
iContribution from the Entomological Laboratory of the Bussey Institution, Har-
