NOTES ON BRACONIDZ. 125 
which the imago removes from one extremity of the cocoon 
when emerging is invariably most regular in shape, those 
cocoons which show a ragged or uneven orifice having always 
been tenanted by hyperparasites. 
These hyperparasites are very frequently met with, and 
probably every species of Apanteles is subject to their attacks. 
The majority of them belong to the Ichneumonideous genera 
Hemeteles and Mesochorus; the species are not particularly 
easy to identify, those mentioned in the following notes I have 
determined, principally, by the aid of Morley’s ‘ British Ichneu- 
mons,’ vols. 11 and v. 
There is no doubt the genus Apanteles is somewhat unwieldy, 
and attempts have been made at subdivision. With this end in 
view, Ashmead created the genera Pseudopanteles, Parapanteles, 
Protopanteles, and Urogaster, which seem to have been founded 
on merely specific characters (see Viereck, ‘Proc. U.S. Nat. 
Mus.,’ vol. xl, p. 476, etc.). In working at our British species, 
Ashmead’s divisions have seemed to me rather puzzling, so that 
I have preferred to rely on Marshall’s sections as described in 
the ‘ Trans. Entom. Soc.,’ 1885, p. 157. 
It is often rather difficult to separate the species, indeed 
many can be distinguished more readily by their biology than 
by morphological characters. The following divisions are almost 
identical with those suggested by Marshall, with the exception 
that I have ventured to unite his first and third sections. 
Section 1.—First abdominal segment truncate behind, 
never more than twice as long as broad. Second segment never 
less than half as long as third. Terebra very short. 
Section 2.—First abdominal segment as in Section 1. 
Segment 2 usually less than half as long as 8. ‘Terebra 
elongate. 
Srecrion 3.—First abdominal segment at least twice as long 
as its medial breadth, lanceolate or rounded at the apex. 
Terebra variable.
