XXXIl. — T/ie Status q/* Parabates, Foerster, and Parabatus, 

 Tiionison [fli/nienoptei-a, Ichnennionidie]. By J. Chestku 

 Hkadley, Ph.D., (Jornell University, Itiiaca, N.Y. 



'J'here 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 

 Puniscus by reason of the front wing lacking an areolct. 

 Tlie only known Palearctic species in whieli this is normally 

 the case is nigr'icarpus (in milit'erativ, 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 -IBth published opinion has ruled on such cases that tiie 

 genera are valid. " If (as in Aciastus, Foerster, 1808) it is 

 not evident from the original puhlieation of the genus, how 

 many or what species arc 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 Aciastus rujipts, 

 Ashmead, 1902) beeomes ipso fucto the ty|)e." 



The species ritfipes referred to as an exam))le, having been 

 described subs«;fineMt to the publication oi Aciastus , 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- 

 se(|Uontly. 



The opinion states that the first species published in 

 cotmection with the genus becomes ipso facto type, and we 

 accordingly may infer that in the case of several sjjecies 

 being simultaneously included in the first mention of species 

 in the genus, without one of them being designated as type.
