Metulosonia Hoeni, sj). n. 



Elongate-oval, pitchy-brown, glossy ; head sparingly but rather coarsely punc- 

 tured ; epistoma finely and rather closely punctured ; prothorax finely and not 

 closely punctured, near the sides are some scattered, large, coarse punctures ; a well- 

 marked oblique impression at each side the median basal lobe, which has also an 

 ill-defined, shallow depression on its middle ; scutellum sparsely but distinctly 

 punctured ; elytra seriate-punctate, the punctures rather large, especially at the 

 sides ; intervals flat, faintly punctulate ; under-side and legs dark reddish-brown, 

 glossy, almost impunctate ; flanks of prothorax faintly longitudinally wrinkled ; 

 abdomen a little coarsely (but not closely) punctured, and reticulate-rugose at 

 the sides ; prosternal process with a well-marked impressed line dovra the centre, 

 between the coxaj, the end acutely pointed ; intercoxal process somewhat rounded 

 at apex. Length, 3 1 lin. ; -v^idth of elytra. If lin. 



Hah. : Panama ; a single example. 

 Metulosonia egaensis, sp. n. 



Much smaller and relatively broader than the preceding, entirely reddish- 

 castaneous, glossy, the entire punctuation finer ; the prothorax a little less narrowed 

 at the sides anteriorly, the front angles a little less prominent, and somewhat de- 

 pressed, the median basal lobe not depressed on the middle ; elytra wider behind 

 the middle, the apex being consequently more broadly rounded ; prosternal process a 

 little more compressed behind the coxa;, the point less acute, the longitudinal central 

 depressed line obsolete ; intercoxal process narrowly rounded at the apex. 



Length, 2,\ lin. ; width of elytra, 1^ lin.

Peltoides capensis (Dej. Cat., p. 230 — Odjjlestus). 



Size and general aspect of P. senegalensis, Cast. ; the only 

 differences I can detect are (in cajyensis) tlic stronger punctuation 

 of tlie entire surface, both above and beneath, the rows of punctures 

 on the elytra especially being larger ; the presternum longitudinally 

 rugose, or finely plicate, before the coxae, and the prosternal processes 

 plain, not convex or sub-carinate down its length, and rather strongly 

 and closely punctured. The antenuse appear somewhat shorter and 

 stouter, but these organs vary in this respect in different individuals 

 of P. senegalensis. 



It will require the comparison of a number of examples to deter- 

 mine whether these slight differences are 'sufficiently constant to give 

 them a specific value. At present, I possess but a single example 

 of P. capensis, from Port Natal.
