Parabates, Foerster, and Parabatus, Thomson. 323 
solely on the basis of the determination by Herr Sigmund 
Brauns of a North American specimen sent him by 
Mr. Morley as “ Opheltoideus sp.?” But there is not the 
slightest evidence that the determination was correct, or that 
Herr Brauns had any more knowledge of what Opheltoideus 
is than has Mr. Morley or anyone else who has not seen 
Ashmead’s specimen of johnsont. 
Mr. Morley’s key to the genera (1913, 7. c. p. 101) makes 
no provision at all for Parabates, Foerster, s. s. (i. e. nigri- 
carpus, Thomson, a species without an areolet), as it neither — 
agrees with his Paniscus and Parabatus, both of which are 
stated to have an areolet, nor with Parca which is the only 
provision made for species with the areolet absent, but which 
differs in other respects. 
Mr. Morley does not make it clear what species of Paniseus 
lack the oecipital carine. It is weak in even the type- 
species, testaceus, and readily may not be associated with 
the relative length of the median and submedian cells, as he 
suggests, nor with any other structural character, 
To sum up, there seem to be a group of species which have 
the nervulus interstitial (m—cu and M,+Cu, opposite) and a 
group which do not, but of the former two or three species 
have the nervulus sometimes a little beyond the apex of the 
cell, and one species (franki, known from a single German 
female, which may be abnormal) has it widely before the 
apex of the median cell. On the other hand, specimens of 
testaceus, the type-species of Paniscus, determined for me by 
Professor Schmiedeknecht, show a varying distance between 
the apex of the median cell and the nervulus, in one case the 
distance being quite insignificant. Secondly, nigricarpus, 
millierate, pallescens, tarsatus, gansuanus, virgatus, latungula, 
eristatus, and franki are stated by Schmiedeknecht (in giving 
his generic description) to lack an occipital carina, while he 
states that all of the species of Pantsous possess such a carina. 
So far as I have observed, this distinction holds, and probably 
is the best primary character available for group-definition, 
Morley, treating of additional species from other parts of the 
world, finds species lacking the carina which, on the basis of 
the venational character just discussed, he treats as Paniscus, 
Finally, nigricarpus and johnsoni* lack an areolet normally, 
but at least also mdllzerate in aberrant individuals. 
* In the case of johnsoni probably not enough individuals are known 
to be sure what is normal.
