of Calleptiles latipennis Haliday of 1872 in a series of short papers 
on the Economy of the Chalcidiae merely stating that Trichogramma , 
meaning Calleptiles, is the smallest and most simple of the family 
and that it lives in the eggs of Lepidoptera. Dours’ Catalogue 
Synonymique des Hymenopteres de France appeared in 1874. This 
quotation comprises what it contains of the family under considera- 
tion: 
C. Trimera. 
Subfam. XXII. Trichogrammatidae. Foerst. 
Trichogramma. Westw. 
1. T. evanescens. Westw. 
Chaetosticha. Walk. 
1. C. signata, Ratz. Par. de Rhynchites betulae. 
Blastophaga. Grav. 
1. B. psenes. L. 
2. B. grossorum. Grav. 
b. sycomori. Westw. (p. 111.) 
It is needless to say that this list is without value. 
Four years afterward the Swedish entomologist Thomson 
published his classification of the Chalcididae ( = Pteromalidae 
Thomson) in which the Trichogrammatidae are classed as the 
tribe Trichogrammina of the section Microcentri. It is very briefly 
described as follows: “Alae lineis pluribus setiferis ornatae. 
Pedes tarsis triarticulatis.” Then follows: “Genus Ophioneurus 4 
Ratzeburg. Alea postcosta marginem alae haud attingente, sed 
in medio fere sigmoideo.” Under this genus, the only one men- 
tioned, 0. grandis Thomson is described. The species is incor- 
rectly placed and belongs, as far as I am able to determine from its 
description, to Poropoea Foerster. 
In 1879 (Riley; Comstock, 1879) Riley described Trichogramma 
pretiosa from the eggs of Alabama , comparing it with minutum and 
stating: “I have proposed the generic name of Pentarthron for 
minuta in MS. now in Mr. Scudder’s hands, but until the allied 
genera are better characterized than at present, it is best to use 
the old genus Trichogramma .” In the same year Westwood pub- 
lished an important paper in this connection adding several new 
species and some additional descriptive notes on described species 
and genera. Here he discusses Prestwichia aquatica Lubbock
