and species, which were included in the family Eulophidae or 
sometimes within the Encyrtidae. The earliest authentic mention 
of a species was, presumably, -by Peck (1799) who mentioned 
Trichogramma minutum Riley as Encyrtus species. Over a third 
of a century later, Curtis (1829) mentioned Calleptiles latipennis 
Haliday under the binomial name “Microma latipennis,” but gave 
no description of the species (see Haliday, 1833). This was the 
second mention of a species. Curtis mentioned latipennis in the 
following manner: 
“595 Microma, W. 
* 1 flavopicta W. 
f 2 flavoscutellata Curt. 
* 3 atra W. 
f 4 latipennis Curt. 
f 5 Iridis Curt.” 
Species of the family were next written about and the first 
genera discovered and described nearly simultaneously by two 
British entomologists, Westwood (1833) and Haliday (1833), the 
latter describing the ‘'Microma latipennis” of Curtis as Calleptiles 
latipennis Haliday and the former describing Trichogramma evan- 
escens. Because of the fact that this later genus and species was 
described one month earlier than the Calleptiles it became the type 
of the family. Trichogramma was described in June, 1833, and 
Calleptiles in July of the same year. Westwood thought the 
genus Trichogramma to be allied with what is now Aphelinus 
Dalman, hence eulophid, while Haliday placed Calleptiles in an 
unnamed tribe by itself. From the very beginning, these two 
genera fought for supremacy; even in its original description 
Calleptiles was questioned as being a synonym of Trichogramma 
by the editor of the journal in which it was described and subse- 
quently it has been rejected as a synonym of the more fortunate 
Westwoodian genus by nearly every systematist dealing with the 
family excepting Aurivillius (1897). From the literature, I con- 
clude that the two genera are distinct. 
During the following year, in the laboriously compiled Hymen- 
opterorum Ichneumonibus, Nees ab Esenbeck (1834) under the 
general heading “Genus XV Eulophum inserenda sunt genera, 
Eulopho similia,” gave a brief paraphrased copy of Westwood’s 
description of Trichogramma and under Trichogramma evanescens
