Neuropterous Fauna of Japan. 183 
pairs of wings, dusky ; pterostigma long and narrow, 
brownish; in the anterior wings the upper half of the 
3rd cubital cellule is narrower, the dividing vemlet some- 
what oblique; 15—16 nervules between the radius and 
the sector ; the two series of gradate veinlets nearly 
parallel. 
One example in the Leyden Museum ; captured by Von 
Siebold. A pretty and strikingly-marked species.

Notwithstanding that the species of this genus already 
known from Japan are both numerous and handsome, we 
are (as I have stated in the introductory remarks) pro- 
bably only acquainted with a small proportion of those 
that exist. In 1867, in the Journal of the Linnean 
Society, Zoology, vol. ix. pp. 256—258, I enumerated five 
species; since then others have been discovered. They 
appear to constitute a group (extending into North China 
and Amur Land), one of the peculiarities of which con- 
sists in the fact that the sub-costa in all the wings scarcely 
extends beyond the middle of the costal margin, a pecu- 
liarity only to be found in one true European species 
(P. alpina), which otherwise has no intimate connection 
with the Japanese group. I propose to describe all the 
species, as an incentive to resident entomologists in Japan 
to extend our knowledge of the genus.

Body totally deep black (in the ¢ with reddish mem- 
branous lateral abdominal lines and sometimes with pale 
margins to the segments); the legs pale, with fuscescent 
femora. Wings broad, whitish, with black veins; a very 
broad black fascia rather beyond the middle, and the apex 
also very broadly black, this space somewhat sinuate inter- 
nally; occasionally there are two or three small black 
spots before the fascia. In the ¢ the spots before the
