IV22 Dr. J. Chester Bradley on the Status of 



der Cubitalader niclit in einen Spitzen winkel zusaramentref- 

 fend, letztre daher nicht ans der Spitze der Diskokubifalzelle 

 liervorgehend." A comparison of the wing of nijricarpus 

 with an Eremotylns (with which genus and Alloeamptus 

 Foerster is comparing Parabates) makes his meaning 

 obvious. 



Ashmead (1900, ' Classification of the Ichneumon Flies,' 

 Proc. U.S. Nat. Mus. xxiil. 96) recognising minutiae 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 Parabates, 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 Ichneumonidse,' ii. 129) 

 writes: " Parabatus, Thomson. Knowm from Paniscus 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 do not always find associated 

 with an occipital costa, and I have been obliged consequently 

 to place species with this capital structure occasionally in the 

 genus Pam'scus. 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, 0. johnsoni. 

 I have already pointed out (Revis. Ichn. Brit. Mus. i. 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 ])erfectly 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 Ojiheltoideus is an 

 anomalinc genus is open to grave doubt. It was arrived at
