Notes on the Hymenoptera Chalcidoidea. 
By A. A. GriRAULT, Brisbane, Queensland, Australia. 
1. A New TrICHOGRAMMATID FROM THE UNITED STATES. 
In the Transactions of the American Entomological Society, 
Volume XXXVII, 1911, pp. 2-6, pl. I, figs. 1-2, a new genus 
and species of the Chalcidoid family Trichogrammatide was 
described with the name of Aphelinoidea semifuscipennis 
Girault. Recent additions to this genus comprising four new 
species discovered in Australia lead me to review the group 
and I now find that in the material upon which was based the 
description of the type of the genus two distinct species were 
represented instead of but the one. This error came about 
very naturally by supposing the two distinct forms represented 
in the description of semifuscipennis to be the two sexes of that 
species. If the original description of the genus be consulted, 
it will be seen that the male was described as differing from 
the female by a very striking characteristic, a kind not usually 
sexual, namely the presence of a broad naked path across the 
fore wing. Later examination of one of the so-called males 
upon which the description was based (captured at Urbana, 
Illinois, July 27, 1910) led to the discovery that it was a fe- 
male, evidenced by the fact that the genitalia could not be dis- 
tinguished from that of the females of the genus, though the 
actual presence of an ovipositor could not be demonstrated. 
Nevertheless the reasoning stands thus: 
(1) This specimen could not be distinguished structurally 
from the females of the other four species and its ovipositor 
was probably concealed within its valves, which were visible. 
(2) Males of the genus with the exception of the two so- 
called of semifuscipennis are unknown (about forty specimens 
of the genus have been captured, all females). 
(3) Secondary sexual characters in the family are usually 
confined to antennal structures (or some more fundamental 
change than that mentioned previously), and 
(4) Differences in degree of wing fumation and arrange- 
ment of the discal ciliation are known to be specific characters
