( .517 ) 



jjimctatc-striate, the slionldcrs very ])roruiiieiit and tuberculiform, the interstices at 

 the sides longitudinally costate, impunctate, the basal lobe at the sides very strongly 

 produced, obliquely sha}ied with some strong pnnctnres ; legs black, tarsi obscure 

 fulvous ; pygidium strongly punctured. 



Hab. Kuilu. 



Allied to C. niffritellas ISuffr. but entirely black, the thorax much more 

 strongly punctured. The single specimen being glued to a card I am unable to 

 say anything about the underside. 



Chlamys africanus sp. nov. 



Black, the first joint of the antennae and the labrum fulvous, head rugose, 

 thorax transverse, the middle portion raised into two rows of tubercles, eacli side 

 with two tubercles, elytra deeply jiuiictured, the base with one, the disc and apex 

 with several transverse and longitudinal elevations. 



Length li line. 



Of parallel, nearly snbcylindrical shape, entirely Idac.k, the head rugose througli- 

 out, flat, the eyes renilbrni, deeply notched ; tliorax very strongly transverse, the sides 

 deflexed, the middle portion raised into a high bump, divided by a deep longitudinal 

 groove, the edges of which are divided into four tubercles each, running parallel to 

 each other from base to apex, the sides with two other similar tubercles, ])Iaced 

 transversely, the interstices reticulate in a star-shaped way ; scutellum transverse, 

 <lilated at the ajiex ; elytra strongly punctured, the suture serrate, I'aoh elytron with 

 about six or seven tubercles and ridges, placed as follows : a smiill tubc^rcle at the 

 base near the scutellum, a short trausvers<' ridge near the middle, preceded by a 

 small tubercle near the base and followed by two short transverse ones at the 

 middle, near the apex three other strongly raised tubendes are placed, forming an 

 irregular square ; those elevations at the middle are more or less connected by a 

 somewhat raised ridge ; pygidium rugose with a slightly raised central ridge ; 

 underside deeply foveolate-jiunctate, prosternum widened, anteriorly reduced to a 

 narrow elongate ridge towards the base. 



Hab. Sierra Leone. A single specimen. 



This small Chlamys is evidently closely allied to C. holumnni Lac, the (jnly 

 other African species known, but I cannot identify it with that insect on account of 

 the different sculpture of the thorax and other details ; the head has no smooth space 

 as described in Lacordaire's insect, but is closely punctured throughout, there are 

 a few small fulvous spots visible at the lower portion of the face : the antennae are 

 unfortunately broken off, except the fulvous basal joint ; the thorax has about 

 twelve isolated round tubercles, eight of which occupy the median elevation ; in 

 C. bohemani the thorax has some raised ridges whicli partly unite ; the design of the 

 elytra is very difficult to describe, and does not materially difter from many South 

 American forms, but the ridges and tubercles, especially those near the apex, are 

 very highly raised and acute, two longitudinal tubercles at the apex being especially 

 conspicuous. 



Colasposoma viridimarginatiim sp. nov. 



Dark metallic blue, the lateral margin of the tliorax and elytra and the tibiae 

 metallic green ; thorax finely, closely and evenly piuictured, elytra I'losely )junctuieil 

 in irregular rows, the interstices flat. 



Length 3 to 4 lines.
