XXXIL.— The Status of Parabates, Foerster, and Parabatus, 
Thomson [ Hymenoptera, Ichneumonide]. By J. CHESTER 
BRADLEY, Ph.D., Cornell University, Ithaca, N.Y. 
‘THERE is a confusion concerning the status of the so-called 
genus Parabates. It was described by Foerster (1868) with- 
out mention of included species, being separated from 
Paniscus by reason of the front wing lacking an areolet. 
‘The only known Palearctic species in which this is normally 
the casé is nigricarpus (in millierate, Kriechbaumer, it is in 
some individuals lacking). Specimens of virgatus without 
areola are not known to occur. 
The International Commission on Zoological Nomenclature 
in its 46th published opinion has ruled on such cases that the 
genera are valid. “If (as in Aclastus, Foerster, 1868) it is 
not evident from the original publication of the genus, how 
many or what species are involved, the genus contains all of 
the species of the world which would come under the generic 
description as originally published, and the first species 
published in connection with the genus (as Aclastus rufipes, 
Ashmead, 1902) becomes ipso facto the type.” 
The species rufipes referred to as an example, having been 
described subsequent to the publication of Aclastus, Foerster, 
it is evident that the opinion means to include in the genus 
all species in the world which fit the original description, 
whether already described at that time or described sub- 
sequently. 
Lhe opinion states that the first species published in 
connection with the genus becomes c¢pso facto type, and we 
accordingly may infer that in the case of several species 
being simultaneously included in the first mention of species 
in the genus, without one of them being designated as type,
