MALACODERMATA. 263 
a Lucidota, viz. distinctly impressed in the centre, the margins reflexed, and rather 
strongly punctured, except on the disc, of which the convex portion is smooth and of a 
deeper orange colour. The scutellum is distinct and brightly yellow, the elytra have 
two or three raised lines as in L. bella but not quite so well defined, and the margin of 
the elytra is not reflexed at the apex in this insect as it is there. In addition to 
the species from North and South America, which closely resemble each other, I 
may call attention to the fact that I have described in the notes from the Leyden 
Museum, Vol. iv. p. 102, a species of Vesta almost precisely similar to these insects, 
but which inhabits Sumatra. The generic differences separating these insects are 
hardly so great as those which separate this species from Photinus ruficollis. 
15 (a). Photinus montanus. (Tab. XII. fig. 10.) 
Ater, ovatus ; prothorace transversim subquadrato antice prominulo, disco utrinque macula rufa notato. Long. 
8 millim. ¢. 
Mas. Segmentis quinto et sexto albis, eburneis, septimo et pygidiali pallidis, genitali nigro. 
Hab. GuatEMALA, Volcan de Agua (Champion). 
A very distinct species from any yet recorded in this work, but allied to the species 
which follow. It is easily to be recognized in this genus by the thorax being black 
with a squarish orange-red spot on each side. The very white luminous ventral parts will 
separate it from the following, with which when it is compared, the small and transverse 
thorax will be noticeable. The specimens were found at the high elevation of 8500 
to 10,000 feet. 
15 (s). Photinus nigro-limbatus. 
Niger; prothorace albescente, subdiaphano, disco nigro utrinque miniato, margine laterali tenuissime nigro ; 
elytris sordide pallidis limbo toto tenuissime nigro ; pedibus pallidis, tibiis tarsisque subinfuscatis. Long. 
81-10 millim. ¢ Q. 
Mas. Segmentis quinto et sexto flavis subeburneis, apicalibus pallidis, genitali nigro. 
Femina. Segmentis quinto, sexto et apicali totis albido-flavis. 
Hab. Guatemata, Volcan de Agua (Champion). 
In form and colouring of thorax rather like P. lunicollis, to which this species is 
clearly allied, but from which it differs in the very pale colour of the elytra, and in 
their being very finely margined with black. This narrow margin extends all round 
the thorax and the elytra, being faint or quite evanescent in the front of the thorax, 
and at the base of the suture. The colour of the elytra is very nearly that of P. 
infirmus, but the form is that of P. /unicollis. Examples occur without the narrow 
black margin to the elytra. 
Photinus guatemale (p. 44). 
To the Guatemalan localities given, add:—Quiche Mountayps, Totonicapam 8500 to 
10,000 feet (Champion). |
