illustrations of generic types they contain such grossly perverted 
details of structure that their existence is obstructive. Newman, 
during this same year (1871) records Trichogramma evanescens 
Westwood ( = Calleptiles latipennis Haliday ?) from the eggs of 
“Smerinthus populi,” which were determined by Walker for a 
correspondent of the Entomologist of London. 
The following year Walker (1872) in his Notes on Chalcidiae, 
parts VI and VII, translates almost literally Foerster’s (1856) 
Uebersicht of the genera, exactly as follows (id., part VI, p. 105): 
Fam. 20. Trichogrammidae. 
A. Fore wings with lines of hairs. 
a. Humerus and ulna not united Poropoea. 
b. Humerus and ulna united. 
* Antennae 8-jointed. Humerus forming a curve. . .Trichogramma. 
** Antennae with less than eight joints. Humerus not forming a 
curve. 
t Wings fringed around with long hairs Chaetosticha 
ft Wings with some short hairs between the radius and the tip. 
t Antennae 7-jointed, with a ringlet and with a 4-jointed club. 
Lathromeris. 
tf Antennae 6-jointed, with no ringlrt and with a 3-jointed club. 
Centrobia. 
B. Fore wings without lines of hairs. 
a. Antennae 7-jointed Asynacta. 
b. Antennae 6-jointed. 
* Fore wings broad, with a pubescent border Brachista. 
** Fore wings narrow, fringed with long hairs Oligosita. 
Poropoea and Ophioneurus, Ratz., are one genus. Brachista, Hal., is 
altered by Foerster to Brachysticha. P. 105. 
In part VII of the same work (id., p. 114) Calleptiles latipennis 
Haliday is figured under the name of Trichogramma evanescens 
Westwood — the adult female with the wings spread and enlarged 
tarsus, fore and posterior wing and female antenna, the figure 
being practically the same as given previously by the same author 
(Walker, 1842), with minor details added or changed, giving the 
impression of a patched original. This figure has already been 
commented upon. It was in 1872 also that Packard recorded 
the description of Trichogramma minutum Riley and the provisional 
proposal of Pentarthron Riley for that species. 
Again the following year, Walker (1873) republished the figure
