to several Photini, perhaps to P. cinctellus more than any other, also to some of the 
Photurides such as Photuris lucidicollis. Among the Lucidote its general appearance is 
that of LZ. osculatii. The following characters will, I think, distinguish it from any Luci- 
dota yet described. The antennz are simply compressed, very slightly serrate in the male 
only ; they are entirely fuscous-black. The rosy-red colour of the fifth and sixth ventral 
plates is very conspicuous, and the fifth has two whitish raised spots; this rosy colour 
is also very conspicuous in the prosternum and internal structures of the prothorax, 
and is of course the source of the same vivid tint round the fuscous disc of the 
pronotum. 
A very large number were taken by Mr. Champion in the forests of the “tierra caliente” 
at Bugaba, where it was very common in the rainy season, and often to be seen sitting 
on leaves in the daytime.

This species was accidentally omitted altogether in the first part of this volume. 
The examination of four specimens captured by Mr. Champion, of which two are males, 
satisfies me it is a Lucidota; the long compressed slightly serrate antenne of the male, 
together with the black abdomen with a single luminous point, are conclusive. It 
is easily recognized by the grey leaden elytra with a broadish white margin of even 
width from the shoulders to the apex, which has a greenish-yellow tint. The disc of 
the thorax is wholly pitchy in the Peta Blanca specimens, which were captured on the 
wing in the daytime in the dense forest at an elevation of 7000 feet.

This is a very distinct species belonging to a series with rather small thoraces, and 
well developed and somewhat expanded elytra. The thorax is even and shining, a 
few tubercles are noticeable on the disc, and sometimes even a faint carina; the 
antennee of the male are three-quarters of the length of the body, or rather more simply 
serrate, with the three apical joints conspicuously pale; the legs are fuscous-black. 
The underside of the thorax is much tinted with rosy-red; but this appears not to be a
