324 On the Status of Parabates, Foerster, dc. 
Since there seems, therefore, to be no strongly distinctive 
structural character between these groups, and especially 
since there seems to be no association of structural characters, 
their logical treatment would seem to be as at most subgenera 
of a single genus, Paniscus. 
The arrangement and synonymy will therefore be :— 
Paniscus, Gravenhorst. 
Subgenus Paniscus. 
Type.—[Tchneumon luteus, Ross] = Paniscus testaceus, 
Gravenhorst, the only originally included species. 
Distinguishing characters: Head with an occipital carina ; 
nervulus (M,+Cu,) apicad of the apex of the median cell ; 
areolet present and complete. 
Subgenus ParaBatus, Thomson. 
Type.—Ichneumon virgatus, Fourcroy, by designation of 
Viereck, 1914. 
Distinguishing characters: Head without an occipital 
carina; nervulus interstitial, but in some species slightly 
apicad of the apex of the median cell, in another (known 
from a unique and possibly aberrant Palearctic female) basad 
thereof, and in some species not interstitial (according to 
Morley, who would on that account put them in Puniseus) ; 
areolet present in normal individuals, but lacking in aberrant 
individuals of at least one species. 
Subgenus PaRraBATES, Foerster. 
Type.—Parabatus nigricarpus, Thomson, by present desig- 
nation, and by virtue of the tact that it is the only one of the 
species first included in Parabates, which comes under the 
original generic definition. Therefore, not Jchneumon vir= 
gatus, Fourcroy, which was cited as type by Viereck. 
Synonym.— Opheltoideus, Ashmead, of which the type is 
johnsoni, Ashmead. Synonym by reason of the types being 
congeneric so far as published descriptions indicate. 
Distinguishing characters: Head without an occipital 
carina; nervulus interstitial ; areolet absent.
