PHOTINUS. 43 
P.reichei. The difference between it and the former consists in its average larger size, 
the more brightly coloured thorax, and wholly black elytra, and in its having only the 
fifth, or fifth and sixth segments white, whereas in cinctellus the last three plates (and 
often the whole abdomen) of the female is pale. 
From P. reichei, the shape of the thorax (which is the same as that of cinctellus), 
the absence of the slightest tendency to a pale suture, the colour of the ventral 
segments, and pale femora distinguish it. I have only seen a few female specimens 
which I think belong to this species. | 
13. Photinus reichei. 
Photinus reichei (Deyrolle, Sallé’s collection). 
Oblongo-ovalis, nigro-fuscus ; prothorace (disco excepto) flavo, disco convexo, nitido, late fusco utrinque miniato, 
obsolete canaliculato, basi lata; elytris nigro-fuscis, sutura tenuissime flava; abdomine segmentis tribus 
ultimis ventralibus et dorsalibus flavis. Long. 11-14 millim. ¢ 9. 
Hab. Mexico, Parada (Sallé). 
A species with the closest affinity to P. cinctellus, yet probably distinct—the characters 
upon which I should place most reliance being its average larger size, the greater 
width of the thorax at the base, the nearly uniform width of the marginal yellow of 
the sides and front, the dark, almost unicolorous elytra, and the pale dorsal apical 
segments (in P. cinctellus these are often, but not always, fuscous, including the pygi- 
dium). The base of the legs is darker than in any cinctel/us I have examined. 
14. Photinus sturmii. (Tab. IV. fig. 21,2.) 
Ater, opacus, oblongo-ovatus, prothoracis lateribus reflexis, late albidis, nigro limbatis, disco tenuiter carinato, 
elytris tricostatis. Long. 14-17 millim. 9°. 
Hab. Mexico, Puebla (Sallé, coll. Sturm). 
Entirely dull opaque black, with the exception of a broad vitta occupying the 
reflexed portion of the sides of the thorax, which is almost pure white. The extreme 
margin, both lateral and of the base, is narrowly black, and bears a row of punctures. 
The disk is dull black, widest at the base, with a very fine but distinct carina (in one 
specimen, however, this is posteriorly converted into a very fine channel). The elytra 
have three distinct coste, the discoidal one prolonged to near the apex, the other two 
vanishing before the middle. The underside is..a little smoother, but scarcely 
shining. Se 
Four specimens, all females, in Sallé’s collection (one of which is labelled P. lucifera 
in Sturm’s writing), and one in the British Museum, are all I have seen of this species. 
I have not adopted the name /ucifera, as it has been used for a species of Pyrectomena, 
and might thus produce confusion.
