Nearly of the same size and not unlike P. amwna; distinguished, however, by the 
form of the thorax, of which the sides are here narrowed towards the front, by its 
colour, which is of a deep red-brown on the disk, and by the general dark fuscous- 
black opaque body and elytra. The head is black above, face below the insertion of 
the antennz yellow, with a linear spot in front above the labrum. The basal joint of 
the antenne is sometimes pale beneath. ‘The thorax is punctured rather coarsely all 
over and opaque; a short obsolete channel on the basal half of the disk. The elytra 
are opaque, with pale margins not reaching their apex; in one specimen the suture is 
slightly paler; scutellum black, a character which will always separate this species 
from P. amena. 
Section III. External claw split in both sexes.

One of the most abundant and widely dispersed of the Lampyride, distributed over 
the whole of the northern continent below latitude 45° north, and even reaching the 
southern continent. It is probably chiefly to this species that those brilliant appear-
