Girault, Trichogrammatidce.

Subfamily I. Chcetostrichince Girault. 
Submarginal vein of fore wing not reaching the costal wing 
margin but joining directly with the incurved proximal end of 
the marginal vein, the latter curved, the distal end of the sub¬ 
marginal, the marginal and stigmal veins forming a regular sigma 
or arch whose apex is at about the middle of the marginal vein, 
where it reaches the costa; or the veins forming a regular bow at 
the marginal vein. Venation of fore wing curved. 
This subfamily includes the following genera: Chcetostricha 
Haliday, Brachista Haliday, Oligosita Haliday, Centrobia Foers- 
ter, Lathromeris Forester, Ophioneurus Ratzeburg, Prestwichia 
Lubbock, Pterygo gramma Perkins, Aphelinoidea Girault, Tumid- 
iclava Girault, Abbella Girault, Zaga Girault, Uscana Girault, 
Ufens Girault, I ttys Girault, Japania Girault, Tumidifemur Gir¬ 
ault, Uscanella Girault, Uscanoidea Girault and Brachistella Gir¬ 
ault. In order to facilitate recognition of the genera I have estab¬ 
lished the following tribes, none of which, however, appear to be 
natural groups. But I have reduced the value of the kind of 
discal ciliation to a generic basis. 
Antennal funicle present—Tribe I. Chcetostrichini. 
Genera: Brochista, Oligosita, Prestmichia, Chcetostricha, Cen¬ 
trobia. I ttys, Abbella, Japania and Brochistella. 
Antennal funicle absent— Tribe II. Lathromerini 
Genera: Lathromeris, Ophioneurus, Ptery go gramma, Aphel¬ 
inoidea, Tumidiclava, Zaga, Uscana, Uscanaoidea, Usca¬ 
nella and Tumidifemur. 
Table of the Genera of the Chcetostrichini. 
A. Ovipositor not exserted nor prominent, nor is its valves. 
B. Antennae 8-jointed. 
C. Antennae bearing’ two ring-joints, one funicle joint and a 
3-jointed club. Fore wings broad, distad with long marginal 
cilia. Brachista Haliday (Type: Brachystira pungens Mayr). 
CC. Antennae bearing one ring joint, two funicle joints and a 
3-jointed club. 
D. Fore wings with the discal ciliation normal. 
Fore wings moderate in width, the marginal cilia at apex 
moderately short; adbomen conic-ovate; pedicel of an¬ 
tennae larger than funicle; stigmal vein nearly neckless.
