The males of Lathromeris, Uscana, Uscanoidea, Aphelinoidea, Pterygo- 
gramma and Tmnidiclava agree with the females excepting the usual second- 
ary abdominal differences; the males of Ophioneucus, Lathromerella, Lathro- 
meroidea, Lathromeroides, Haeckeliania, Zaga, Tumidifemur and Uscanella 
are unknown, 
SUBFAMILY II. TRICHOGEAMMATINAE (gIRAULt) (nEC ASHMEAD) 
Submarginal vein of fore wing not reaching the costal margin but joining 
directly with the incurved proximal end of the marginal, the latter curved, 
the distal end of the submarginal vein, the marginal and stigmal veins, 
forming a regular sigma or arch whose apex is about at the middle of the 
marginal vein where the latter reaches the costa; or the veins forming a 
regular bow. Venation of the fore wing curved. 
Tribe 1. Trichogrammatini 
The venation of the fore wing forms a bow, 
A, Antennal club solid. Ovipositor not exserted. One ring-joint. 
a. Antennal funicle 2-jointed, the antennae 6-jointed. 
Antennal funicle with minute bladder-like appendages. 
Fore wings relatively narrower, their marginal cilia moderately 
long; male antennae distinctly 8-jointed. Trichogrammatoidea 
Girault (Type: Chaetostricha nana Zehutner) 
Antennal funicle without bladder-like appendages. 
Fore wings relatively broader, their marginal cilia short; 
male antennae not distinctly segmented, apparently only 
4-jointed, the distal joint long, nodular — scope, pedicel, ring- 
joint and a long nodular flagelluni. Abdomen sometimes 
pointed, the ovipositor slightly exserted. Trichogramma West- 
wood (Type: T. evanescens Westwood) 
b. Antennal funicle 1-jointed, the antennae 5-jointed. 
As in Trichogrammatoidea nearly but no bladder-like appendages 
and the marginal cilia of the fore wing are short; venation form- 
ing a very flat bow; stigmal vein a mere footlike clava from the 
marginal. Paratrichogramma Girault (Type: P. Cinderella 
Girault) 
B. Antennal club 3- to 5-jointed, the antennae 8-jointed, the funicle some- 
times absent. 
Antennal club 3-jointed, the funicle 2-jointed. 
Abdomen subcylindrical, the thorax long; one ring-joint (male). 
Calleptiles Haliday (Type: C. latipennis Haliday) 
Antennal club 5-jointed, the funicle absent. 
Abdomen with parallel sides and blunt apex; intermediate tibial 
spurs long and slender; hind wings short; one ring-joint.
