MALACODERMATA. 275 
This species appears to be excessively variable in colour; so much so that of ten 
examples collected by Mr. Champion, no two are exactly alike. The head is black in all 
but one, but with the face below the insertion of the antenne yellow. The thorax is 
transverse, rather square in front, with the margins hardly at all expanded, and the hind 
angles only alittle produced; the disc has a short obsolete channel near the base. Four 
examples have no vitta, the others have a broad black vitta, shining in most, but dull 
and not so wide in var. 8 and in one from the Volcan de Chiriqui. The scutellum is 
black or yellow, varying, as usual, with the mesosternum. The legs are black, or the 
femora as far as the knees are yellow; the tibiee and tarsi are always black. 
The figures are of a male of the type and a female of the var. e, both from Bugaba.

An error has occurred in the description of this species and of P. facialis, both claws 
being split, not, as I have stated, the external claw only: the fact is, it is not easy to 
see the fission of both claws at one time, or unless they are very clean. 
The variety is very distinct in colour, but specimens occur in which the elytra have a 
pale margin and suture, and some with the legs more or less pale from the same locality ; 
the species of this genus appear more variable in these respects than those of Photinus. 
This variety, to some extent, bridges over the distinction between P. amena and P. facialis. 
The variety with pale margins and suture simulates Photinus volcanicus from the 
same region, but is easily distinguished even from the above by the acute and rather 
produced angles of the thorax, the prominent head and eyes of the male, &c. It also 
occurs at a higher altitude. 
Photuris lucidicollis (p. 58). 
To the localities given, add :—Panama, Bugaba (Champion). 
The few specimens I have seen from Bugaba have the disc of the elytra fuscous, the 
suture narrowly and the margins rather widely pale.

This curious race or variety of P. lucidicollis was found by Mr. Champion only in
