322 Dr. J. Chester Bradley on the Status of 
der Cubitalader nicht in einen Spitzen winkel zusammentref- 
fend, letztre daher nicht aus der Spitze der Diskokubitalzelle 
hervorgehend.” A comparison of the wing of nigricarpus 
with an Eremotylus (with which genus and Allosamptus 
Foerster is comparing Parabates) makes his meaning 
obvious. 
Ashmead (1900, ‘ Classification of the Ichneumon Flies,’ 
Proc. U.S. Nat. Mus. xxiii. 96) recognising minutie of 
structure as of generic rank, erects a new genus Opheltoideus 
for the species without an areolet (and which would therefore 
include nigricarpus and be a synonym of Parabates, Foerster, 
as here defined) and separates Parahbates, Foerster, which he 
states is equivalent to Parabatus, Thomson, from Paniscus, 
primarily on the basis that the basal and submedian veins 
are interstitial in the former, or very nearly, and the 
submedian cell longer than the median in the latter. In 
Parabates he further says the discocubital vein is not broken 
by a stump of a vein, while in Paniscus it is usually but not 
always so. 
Morley (1913, ‘ Revision of the Ichneumonidae,’ ii. 129) 
writes: “ Parabatus, Thomson. Known from Paniseus only 
by the continuous basal nervulus through the median 
nervure, thus forming both the upper and_ lower basal 
nervures of a single line; this I donot always tind associated 
with an occipital costa, and I have been obliged consequently 
to place species with this capital structure occasionally in the 
genus Paniscus. Thomson originally placed four Swedish 
species in the present genus and others were subsequently 
added ; but Szepligeti, for some occult reason, has restricted 
Thomson’s genus to a single species, the first here placed by 
its author, which differs from the other three in little more 
than the aborted areolet, and further he has synonymized— 
entirely arbitrarily, I think—Ashmead’s Nearctic genus 
Opheltoideus with its single and still MS. species, O. johnsoni. 
I have already pointed out (Revis. Ichn. Brit. Mus. 1. 60) 
that the latter almost certainly appertains to the Anomalides.” 
Szepligeti’s course in restricting Parabates to the one 
species nigricarpus was not occult, but perfectly logical, 
since it is the only one falling under Foerster’s original 
definition. Nor was it arbitrary to assign Opheltoideus, 
Ashmead, as a synonym, since the published characters of 
that genus leave no other course possible. On the other 
hand, Mr. Morley’s conclusion that Opfeltoideus is an 
anomaline genus is open to grave doubt. It was arrived at
