specimen and perhaps does not belong to Trichogramma; its posi- 
tion is decided elsewhere. This contribution by Westwood is 
timely and throws much light on one genus at least, namely, 
Oligosita Haliday, though the ring-joint of course may not have 
been overlooked by Haliday in the first place. 
During the following year, Ashmead (1880) described Tricho- 
gramma flavus captured on orange leaves in Florida; from the some- 
what crude figure and from the statement in the description that 
the tarsi are 5-jointed, it is obvious that this insect is not a tricho- 
grammatid but its habitus and description make it very probable 
that it belongs to the eulophid subfamily Aphelininae, tribe 
Aphelini. I shall not attempt to place it. 
The remainder of our knowledge of the family is furnished 
largely by American entomologists, commencing with Riley and 
Packard and ending with Ashmead. Packard (1883) redescribed 
Trichogramma as having 5-jointed antennae — scape, pedicel, 2 
funicle joints and a solid club, overlooking the ring-joint; he very 
briefly redescribes Trichogramma minutum Riley from four male 
specimens reared from the eggs of Limenitus disippus and supplied 
by Riley, and also T. minutissimum new species from males and 
females reared from the eggs of Papilio turnus Linneaus. The 
description is very brief. The latter species is correctly placed 
as it is directly connected with the generic description of the genus. 
In 1886 Howard republished a translated synopsis of the Tricho- 
gramminae practically giving Foerster’s (1856) Uebersicht, but 
replacing Poropoea by Ophioneurus and Brachista by Brachysticha. 
No comments are made. The same table is repeated the following 
year by Cresson (1887) who also lists the genus Trichogramma 
from North America with 7 American species, orgyiae Fitch, 
fraternum Fitch and minutum Riley being questioned. The 
positions and validity of these species have already been dealt with. 
This list with the exception of odontotae Howard had been previ- 
ously published by Howard (1885, a) where minutum was held to be 
valid. In the meantime, Howard (1885, h) described Trichogram- 
ma odontotae from the eggs of the coleopteron Odontota suturalis, 
and Ashmead (1888) Trichogramma acuminatum, nigrum and 
ceresarum. The last three species were not true Trichogrammae, 
as the American conception of the genus was somewhat varied, 
and Ashmead later was in doubt concerning at least one of the
