Head finely granulate, the frontal elevations narrowly trans- 

 verse ; clypeus with a central ridge ; labrum piceous, as well as the 

 apex of the mandibles ; antennae extending to the middle of the 

 elytra, blackish, the eighth joint flavous, basal joint elongate, 

 thickened at the apex, secoud short, third tw'u-e as long as the 

 second, fourth joint longer than the preceding two joints together; 

 thorax twice as broad as long, the sides slightly constricted at the 

 base, rounded before the middle, anterior angles furnished with a 

 small tubercle bearing a single seta, the surface minutely granulate 

 and finely punctured, testaceous, the sides with a nari-ow dark 

 band not extending to the margins ; scutellum large and broad ; 

 elytra strongly and closely punctured, the sides with a strongly 

 raised longitudinal costa, extending from below the shoulder to 

 the apex, preceded by a deep longitudinal depression, a narrow 

 sutural and another sublateral band, connected at the apex, 

 metallic greenish : underside and legs testaceous ; the femora 

 above and the tibiae and tarsi fuscous ; tibiae with a small spine ; 

 the first joint of the posterior tarsi as long as the following joints

Hub. Madagascar. 



This species is evidently allied to L. quaterniis, Tairm., likewise 

 from Madagascar, but is much larger, and differs in the colour of 

 the antennae and that of the thorax, as well as in the green bands 

 of the elytra and their strong punctuation, and in the pale under- 

 side. I received a specimen from Herr Erancsik of Hungary, 

 another is in that gentleman's collection. 



LuPERUS NiGROSUTXJRALis, n. sp. (Plate XXXIV. fig. 11.) 



Black, the basal joints of the antennae, the head, thorax, and 

 legs fulvous ; elytra testaceous, finely punctured, the suture more 

 broadly, the margins narrowly black. 



Length If line. 



Head impunctate, fulvous, the frontal tubercles only indicated ; 

 the clypeus with a short central ridge ; antennae extending rather 

 beyond the middle of the elytra, black, the lower three joints 

 fulvous, the third joint slightly longer than the second, the fol- 

 lowing joints elongate ; thorax twice as broad as long, the sides 

 rather rounded, the anterior angles somewhat oblique and thickened, 

 the surface with a few very minute punctures, only visible under 

 a strong lens, fulvous ; scutellum black ; elytra elongate and 

 parallel, pale testaceous or flavous, finely and very closely punc- 

 tured, the margins narrowly black, the suture more broadly so in 

 some specimens : underside black, clothed with greyish pubes- 

 cence ; legs fulvous, the first joint of the posterior tarsi longer 

 than the following joints together, last joint and the claws 

 infuscate. 



Hah. Mashonaland {G. Marshall). Coll. Brit. Mus. and my own. 



Somewhat allied in coloration to the European L. nigrofasciatus, 

 Goeze, but with entirelj^ ftdvous thorax and legs, and narrower 

 elytral black margins.
