Coleoptera. By Martin Jacopy. 
[Received November 31, 1881.] 
Lamprosoma, Kirby. 
1, LAMpROSOMA GRANDE, sp. nov. 
Subglobular, very convex, black below, above brilliant metallic 
green. Head very finely, thorax distinctly punctured ; elytra rather 
deeply punctate-striate, the interstices finely scratched, 
Length 33 lines. 
Hab. Amazons. 
Head very broad, finely and closely punctured, the front with au 
obsolete depression ; clypeus separated from the face by a short but 
deep impression at the sides only, anterior border deeply concave. 
Labrum fulvous. Jaws and antenne black, the basal joint of the 
latter metallic green above, fulvous below. Thorax more than 
three times as broad as long, the sides greatly deilexed, the posterior 
lobe rounded and large, obliquely and distinctly impressed at each 
side, surface closely and more distinctly punctured than the head. 
Seutellum metallic green. Elytra regularly convex, scarcely nar- 
rowed behind, the lateral lobe not much produced, subangulate ; 
each elytron with ten rows of punctures deeply impressed at the 
base, but much smaller towards the apex, the interstices finely 
scratched. Prosternum rather longer than broad, its surface with 
a few deep punctures. 
A single specimen is contained in my collection. 
The present species is allied to L. amethystinum, Lac., L. cunea- 
tum, Baly, and L. canaliculatum, Baly, but differs from all of them 
in the more narrow transverse thorax, broader scarcely attenuated 
shape, the finer punctuation of its head and thorax, and the shape 
of its clypeus; the shape of the thorax is almost that of Lych- 
nophaés laticollis, although to a less extent. On the whole the 
present species bears a great resemblance in shape and colour to 
the last-named insect ; but the appendiculate claws show it to be a 
true Lamprosoma, 
Lycunopnatis, Lacordaire. 
2. LycHNOPHAES AFRICANA. 
Broadly ovate, moderately convex, black. Thorax extremely 
finely punctured and strigose; elytra finely and irregularly pune- 
tured, a scutellar spot and a lateral band from the base to the apex 
metallic cupreous. 
Length 2 lines. 
Hab. South Africa. 
Head convex at the vertex only, subdepressed at the middle, 
finely longitudinally strigose; epistome limited at each side in front 
of the eyes by a short transverse depression. Eyes very slightly
