LamprosomAj Kirby. 



1. LaMPROSOMA GRANDE, Sp. UOV. 



Subglobnlar, very convex, black below, above brilliant metallic 

 green. Head very finely, thorax distinctly punctured ; elytra rather 

 deeply punctate-striate, the interstices finely scratched. 



Length 3i hues. 



Ilab. Amazons. 



Head very broad, finely and closely ))unctured, the front with an 

 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 antennse black, the l)asal joint of tbc 

 latter metallic green above, fulvous below. Thorax more tlian 

 three times as broad as long, the sides greatly deflexed, the posterior 

 lobe rounded and large, obliquely and distinctly impressed at each 

 side, surface closely and more distinctly punctured tbau the bead. 

 Scutellum 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 muth 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. amethystimua, Lac, L. cimea- 

 turn, 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- 

 nophaes laticoUis, although to a less extent . On the whole the 

 ])resent 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. 



LvcHNOPHAiis, Lacordaire. 



2. Lychnopha£s africana. 



Broadly ovate, moderately convex, black. Thorax extremely 

 finely punctured and strigose ; elytra finely and irregularly punc- 

 tured, a scutellar spot and a lateral band from the base to the apex 

 metallic cupreous. 



Length 2 lines. 



Hah. South Africa. 



Head convex at the vertex only, subdepresscd at the middle, 

 finely longitudinally strigose ; epistome limited at each side in front 

 of the eyes by a short transverse depression. Eyes very slightly
