sides very slightly rounded, the extreme lateral margin metallic green ; elytra strongly and rather closel y 
punctate-striate, the punctures distinct to the apex, and with a deeply impressed sutural stria. 
Hab. Guatemata, Cerro Zunil (Champion). 
Two examples. JI am obliged to separate this insect from L. ewruleatus, owing to 
the strong punctuation of the head and elytra, and the cupreous colour of the thorax. 
The elytra in one specimen are violaceous (almost black) in colour; in the other they 
are metallic green; in L. cwruleatus the punctuation is almost obsolete near the apex. 
Lamprospherus minutus (p. 113). 
To the localities given, add:—Panama, Bugaba, Caldera, Tolé (Champion). 
Var. Above brownish-seneous or dark blue. 
This small species seems to be very variable in colour, the specimens from Guate- 
mala being generally bright metallic green, those from Bugaba dark metallic blue, and 
those from Tolé brownish-zneous; there is also a slight difference in shape, some 
examples being rounded, others more pointed at theapex. The filiform (not thickened) 
antennee and the more transverse thorax distinguish it from Chrysodina pusilla, an 
insect found at the same locality. LZ. minutus is the smallest known member of the 
genus, 
8. Lamprospherus semipurpureus. 
Subrotundate, very convex, black, above obscure dark purplish ; the basal joints of the antenne fulvous ; the 
head and thorax finely punctured; elytra remotely and rather finely punctured, the punctures coarser 
towards the base. 
Length 3-1 line. 
Head with a few fine punctures on the vertex, the lower portion and the clypeus more strongly punctured, and 
with a deep longitudinal groove down the centre, not extending to the vertex ; labrum fulvous; antenne 
about half the length of the body, the lower four joints fulvous, the rest black; thorax of usual shape, 
dull purplish, the surface impressed with not very closely-placed somewhat elongate punctures; elytra 
purplish-violaceous, rather strongly punctured anteriorly, more finely so towards the apex ; underside and 
legs black, the anterior tarsi and the knees more or less fulvous. 
Hab. Panama, Volcan de Chiriqui (Champion). 
The dark purplish colour and the black legs separate this small species from its 
allies, Z. janthinus and LL. luctuosus, Lefévre ; it differs from the former in the colour 
of the legs and in the rugosely punctured head, and from the latter in the purplish 
colour of the legs and upperside. 
4, Lamprospherus plumbeus. 
Bluish-black, the labrum, antennz, and legs fulvous; head and thorax opaque, finely punctured and granulate; 
elytra strongly and closely punctate-striate. 
Length 1 line. 
Head broad, minutely granulate, and scarcely perceptibly punctured, the upper portion entirely impunctate ; 
labrum broad, fulvous; antenne more than half the length of the body, fulvous, the terminal joints
