262 SUPPLEMENT. 
I shall, therefore, in future only allude to such cases as appear to me peculiar and 
specific. Such segments as are described by the word “ eburneus” are of a yellowish 
white, and with a shining waxy-looking surface, while such as are simply termed white 
may be assumed to be dull and soft. 
Of this new species a very great number of specimens were collected by Mr. Champion ; 
it was apparently very abundant in the forests at from 2000 to 6000 feet. The males 
were as usual more abundant than the females. 
12 (a). Photinus flohri. 
Nigro-fuscus; elytris nigro-plumbeis, prothorace lete albo-flavescente, disco nigro-vittato utrinque miniato, 
basi lato, lateribus antice valde angustatis ; elytris subdepressis in medio paullulum ampliatis. Long. 8-11 
millim. ¢ Q. 
Mas. Segmento sexto ad marginem, duobus apicalibus cum pygidio totis albis, pygidio segmenta ventralia multo 
superante. 
Femina. Segmentis apicalibus ventrali et dorsali totis cum duobus precedentibus ad margines albis. 
Hab. Mexico (£lohr). 
Sefior Flohr sent me four specimens of a Photinus, which I at first thought identical 
with P. simplex, but which on examination proves distinct; it will be recognized by the 
very beautifully marked thorax, of which the sides narrow strongly from the base. The 
elytra are nearly of the same colour and form as those of P. aurora, P. sanguinicollis, 
and P. albicauda, i. e. totally leaden black and slightly expanded. 
The thoracic vitta is faint on the front margin, but not (as in P. aurora) wholly 
obliterated. 
13 (a). Photinus? brevicornis. (Tab. XII. fig. 9.) 
Nigro-fumosus ; prothorace, scutello, mesosterno, coxis trochanteribus et femoribus aurantiaceo-rufis; antennis 
brevibus, compressis, pubescentibus, versus apicem valde attenuatis, articulis duobus basalibus apiceque 
summo testaceis. Long. 10-11 millim. 9. 
Femina. Segmento quinto ventrali macula mediana alba, apicali (septimo) pallida, utrinque alba. 
Hab. GuateMata, San Isidro (Champion). 
This species is of the size, and above almost exactly of the form and colour of 
Lucidota bella, but the shortness of the antenne and their total want of serration (the 
joints being not at all produced on their inner sides), although we have at present 
seen only two female examples, certainly indicate a distinct species. It may possibly 
be a Lucidota, but in the absence of the male that question cannot be settled. The 
length of the antenne, their want of compactness, and the serration or pectination of 
their joints are among the characters which best distinguish that genus, and these 
are all wanting in the very short compressed joints closely articulated, which we find 
here. It is, however, wholly distinct from Photinus rujficollis, and the light-giving 
white spots are so different from the wholly yellow terminal segments of that species 
that I should not place it very near it; moreover the thorax is much more like that of
