parts which are dark being the antenne (of which, however, the basal joint is partly 
yellow), the mouth-organs, which are dark pitchy, the tarsi, which are always fuscous, 
and the tibie, which, however, are sometimes yellow. 
At present I have only seen four examples, all females. A fifth specimen differs 
in having the head black on the crown and the breast fuscous, and may possibly belong 
to another species.

Mas segmentis ventralibus quinto et sexto emarginatis, albis, septimo apice acuto. 
Femina mari simillima, capite et oculis minoribus segmentoque apicali obconico mox distinguenda. 
Hab. Guatremaa, Cerro Zunil, (Champion). 
Allied to P. simplex, but readily separated by the black head and shoulders. 
The thorax is shining, obsoletely punctured; the elytra are also punctured, and more 
roughly so at the shoulders. The tarsi have the fourth joint, and the others sparingly, 
clothed with yellow velvety pile. 
Only two specimens have yet been sent by Mr. Champion.

One of the most remarkable genera in the family, having the extraordinary number 
of thirty-five to forty joints to the antennz, with those from the third to the last but 
one bearing each a flabellate branch. The three apical segments are evidently highly 
luminous in the two species I have seen. It is a New-world genus, the species at 
present recorded being five or six in number, from Brazil and Peru. It has only been 
met with on one occasion in Central America. |

The very singular and anomalous insects which form this section have been placed 
by most authors among the Lampyride. Lacordaire, it is true, places them at the head
