which, he rightly believes, belongs to this family and not to the 
Mymaridae. The genus Trichogramma is then discussed and 
emended, or rather redescribed, the antenna and fore wing figured, 
and here Westwood shows distinctly a 6-jointed antenna with the 
articulated club in doubt, referring to it thus: “Nor am I clear that 
the large oval apical joint is not in reality composed of two or 
three* joints closely soldered together.” With this conception in 
mind he therefore indicates the supposed several (three) club 
joints by means of dotted lines in the figure, though the impli- 
cation is plain that these joints were not actually seen. As rede- 
scribed, therefore, the antennae are composed of a scape, pedicel 
ring-joint, 2 funicle joints and a solid club — the latter point 
doubted because of the author’s preconception — and these struc- 
tures, coupled with the morphological details of the fore wing as 
figured, are certainly borne out by the species now referred to this 
genus. Westwood then calls attention to th,e fact that Walker’s 
(1842) figure of Trichogramma evanescens Westwood ( = Calleptiles 
latipennis Haliday), “Differs in several important respects from 
my insect and its details, and evidently represents not only another 
species with a dark band across the fore wings, but probably a male 
insect, while mine was most probably a female.” Westwood next 
mentions ( Trichogramma ) Centrobia walkeri (Foerster), “Which 
has the antennae 4-jointed or (if the last joint consists, as the author 
supposes possible, of three joints soldered together) 6-jointed — the 
first of moderate size, the second and third equal, subovate, and 
nearly as large as the basal joint, and the terminal part of the 
antennae forming an elongated oval mass, the whole antennae being 
very slightly setose.” But Foerster leaves no doubt behind him 
concerning the structure of the antennae of walkeri, the figure of 
it and his description showing six distinct joints, three of which 
belong to the club. Poropoea and Ophioneurus signatus Ratzeburg 
are then briefly characterized without criticism. A brief review 
of the whole group is then given, quoting Haliday ’s (Walker, 
1851) synopsis and Foerster’s Uebersicht, remarking that Prest- 
wickia Lubbock must be placed without doubt in the last section 
of Haliday’s synopsis corresponding with the Oligositinae of today. 
Oligosita subfasciata, 0. staniforthii and 0. f nodicornis are then 
figured and described as new and in addition Trichogramma 
( Aprobosca ) erosicornis. The latter was based on a single male
