36 MALACODERMATA. 
The type of coloration of this species (bone-yellow, with elytra and disk of the thorax 
pitchy, with yellow margins) is very common throughout the Lampyride. There are 
both Photini and Photwrides very closely like this species; and the study of the generic 
characters is necessary to avoid their being confused. L. osculatit has long compressed 
antenne with serrate joints.

This is like LZ. apicicornis in having white apical joints to the antenne; but the 
elytra are wholly black, and the thorax whitish and immaculate. The lengthened 
pygidial plate 1 may indicate a section of the genus of which it will form the type. 
8. Lucidota diaphanura, (Tab. IV. fig. 22.) 
Nigro-fumosa, obscura, elytris opacis, prothorace subnitido, disco obsolete canaliculato, utrinque miniato, 
lateribus albidis, extus subinfuscatis; antennis compressis, haud serratis, corporis dimidio longitudine 
equalibus. Long. 12-15 millim. 9. 
Mas abdominis segmentis quinto et sexto ventralibus ad apices, septimo toto et pygidio albis; hoc latiore, 
conyexo, superne carinato, diaphano. 
Femina pygidio angustiore, apice rotundato albo, basi infuscata; segmento ventrali apicali apice triangulariter 
exciso, et (cum penultimi margine) albo. 
Hab. Mexico, Cordova (Sallé). 
A species of Lucidota somewhat resembling and allied to LZ. atra, but larger than that 
species, and at once to be separated by the white apical segments of the abdomen. ‘The 
thorax varies a little in the proportion of its width; and this is in reference to the 
size of the specimens and not to their sex, the larger individuals having the thorax 
more fully developed. The sides narrow ina sinuous manner towards the front, which 
is rather prominent. The disk has a pitchy-black vitta from base to apex. The elytra 
show very indistinct traces of one or two nervures. ‘The head, mouth, palpi, antenne, 
legs, and underside are entirely pitchy black, with the exception of the apical segments. 
In the majority of the males before me the genital or eighth segment is not visible ; 
the seventh is broad, but not equal in width to the pygidium. In two other males 
separated in M. Sallé’s collection the genital plate is visible as usual; the antenne 
are longer, they have the basal joint fuscous. But I do not think they belong to a 
different species.
