ings of genera based on the discal ciliation of the fore wing. A 
glance at his arrangement shows such marked parallelism that the 
thought at once arises that these groups are not natural, since 
parallelism in a small group of this kind would scarcely have 
arisen. Divergence would fulfill the expectations, and, moreover, 
since discal ciliation of the fore wing is more variable (therefore 
less fundamental) than venation of the fore wing, I have con¬ 
cluded that a division based upon the latter would give us a more 
natural arrangement. Consequently, Ashmead’s subdivisions have 
been rejected and others made which I believe more nearly attain 
the truth. 
In August, 1910, I gave a summary of the number of valid 
genera and species of this family, then admitting fourteen genera 
and thirty-two species. Now, I reject two of these genera as syn¬ 
onyms—namely, Pentharthron Riley andWestwoodellaAshmead ; 
but have described fifteen new genera and twenty new species. 
Perkins has added three more species and I have about three new 
genera and two dozen more new species described in manuscript*. 
Thus the family now (December, 1911) consists of thirty 
genera and approximately seventy-five species and two varieties, 
fifty-six species described to date and admitted as valid and recog¬ 
nizable**.

Submarginal vein of fore wing reaching the costal wing 
margin at the point where it joins the marginal vein, the latter 
straight or nearly so, the stigmal vein forming more or less of an 
acute angle with it. Venation of fore wing straight. 
* All Australian specie®. One genus Belongs to> the tribe Trichogram- 
matini ; the species are not catalogued here. The genus mentioned 
ia| based, on Paratrichogramma Cinderella new genus and species and 
is characterized by bearing but a single funicle joint; the antennae 
5-jointed and otherwise as in Trichogramma; the venation is weak, 
the curved marginal vein shorter than the stigmal. The species 
Cinderella is dusky yellowish, the antennae and legs dusky or greyish 
black (proximal two tarsal joints, trochanters, knees and distal 
third of tibiae white); caudal wings colorless; fore wings sooty out 
to riddle of the marginal vein, then clear, its venation colorless 
excepting the brownish stigmal vein and distal, clavate end of the 
submarginal. The genus and special will be fully described later, 
in a more proper place The male is not known. 
** One new name is proposed in this paper because of preoccupation.
