Haliday, MS. 
Here we find the foundation of the classification of the family. 
The genus Brachista had no species named in connection with it 
and consequently is a nomen nudum. The types of the other genera 
were described in the same paper containing the generic diagnoses 
and are Chaetostricha dimidiata Haliday, and Oligosita collina 
Haliday. All of the genera thus far were described as bearing 
6-jointed antennae, Trichogramma Westwood having scape, pedicel, 
3 funicle joints (afterward known to be 1 ring-joint, 2 funicle joints) 
and a solid club; Chaetostricha having scape, pedicel, 1 funicle 
joint and a 3-jointed club; and Oligosita having the same as the 
preceding genus. Calleptiles Haliday is omitted, apparently, but 
here Trichogramma is intended for it. 
In the meantime, Foerster (1851) described a new genus called 
Poropoea based on the species stollwerckii whose existence was 
first mentioned by Stollwerck as previously stated. This genus 
was described as having 7-jointed antennae in both sexes — scape, 
pedicel, 2 funicle joints and a 3-jointed club and its adequate 
description furnished the first definite knowledge concerning both 
sexes; it also had broad fore wings with the pubescence arranged 
in regular lines and the marginal and stigmal veins together form- 
ing a regular arch and allying the genus with Trichogramma ; it is 
further characterized by having in the female a prominent exserted 
ovipositor. It was described from specimens reared from the eggs 
of an attelabid. At the same time Foerster also described another 
species under the name of Trichogramma walkeri bearing 6-jointed 
antennae (no ring-joint, 3-jointed club) and straight marginal 
vein of the fore wing; the latter broad with the pubescence arranged 
in regular lines and the antennae nearly similar for both sexes.
