260 SUPPLEMENT. 
The thorax is also entirely pale at its edges, and the black portion of the disc is 
much less extended. The elytra, especially those of the female, are less deeply black, 
and show no trace of a vitta. 
Of eight specimens collected by Mr. Champion, three are males. 
Photinus meteoralis (p. 38). 
Var. Thoracis disco vitta lata nigra utrinque miniata. 
Hab. Guatemata, Cerro Zunil (Champion), Coban (Sallé, coll.). 
Photinus perelegans (p. 40). 
To the localities given, add:—Panama, Volcan de Chiriqui (Champion). ¢. 
The specimens from the Volcan de Chiriqui are darker, with the margins and suture 
conspicuously pale by contrast, the pygidium being also dark. Mr. Champion remarks 
that this species is highly luminous, as no doubt the males of all species of the 
“‘ Macrolampis” section are. About ten specimens, all males, were found by him at 
the elevation of 5000 to 6000 feet. 
6 (a). Photinus volcanicus. 
Oblongo-elongatus, parallelus, depressus, nigro-fuscus ; prothoracis margine laterali et frontali albido, disco plus 
minusve nigro nitido, utrinque plerumque parum miniato ; elytris fuscis, sutura margineque albis, ante 
apicem et basin desinentibus. Long. 73-10 millim. dg 2. 
Mas. Segmentis quinto et sexto longioribus, lete albidis eburneis ; quarto etiam ad apicem albido. 
Femina. Segmento quinto albido, apicalibus fuscis. 
Hab. Nicaragua, Chontales (Janson); Panama, Volcan de Chiriqui, Bugaba, Tolé 
(Champion). 
This is the insect referred to at p. 47, anted, under P. pulchellus, as differing from 
the type. Further study of a very large series brought by Mr. Champion from Panama, 
enable me to describe it as quite distinct. It is, in fact, one of the Macrolampis 
section, and I have no doubt it is a widely spread and abundant species. It is larger 
and longer than P. pulchellus, and (apart from the luminous segments of the male) the 
greater amount of black on the disc of the thorax, the legs not pale at their bases, &c., 
will separate it. The only other species to which, for size and colour, it can well 
be compared, is P. cinctellus, but its form is wholly different, not being in any way 
oval or convex. The Chiriqui specimens are (as in other species already noticed) 
darker when found at elevations of 5000 to 6000 feet, than those from 2000 to 4000 
or lower altitudes. 
6 (s). Photinus infirmus. 
Pallide testaceus vix albescens; capite nigro; thorace disco perobsolete canaliculato, miniato, interdum subin- 
fuscato ; abdomine basi fusco. Long. 7-11 millim. ¢ @Q.
