Length 3 millim. 



Head strongly and remotely punctured, strongly narrowed 

 between the eyes, the latter very large, deeply notched ; clypeus 

 transverse, distinctly separated from the face, im punctate ; antennae 

 extending beyond the middle of the elytra, the lower five and the 

 apical two joints fulvous, the others black : thorax about one-half 

 broader than long, the sides strongly rounded and somewhat 

 \A-idened behind the middle, the anterior portion deflexed, the 

 surface rather sparingly impressed with deep foveolate punctures, 

 more crowded at the sides, the middle with a few punctures only, 

 tlie colour dark fulvous ; scutellum smooth, fulvous; elytra wider 

 at the base than the thorax, subcylindrical, flavous, the base with 

 a distinct transverse depression, very strongly punctate-striate, the 

 punctures round and large, the outer two or three interstices 

 costate ; below and the legs flavous, sides of the breast darker ; the 

 femora armed with a small tooth. 



Huh. Cameroons (Conrad). 



This little species, which has the typical constriction of the 

 intraocular space, will not be difRcidt to recognize, on account of 

 the colour of the antennae and the extremely deep punctuation of 

 the thorax, which differs in this respect from any species of the 

 genus at present known. I received a specimen from Dr. Kraatz, 

 another is iu that gentleman's collection. 



OiDOSOMA Quedenfeldt. 



I have very little doubt that this genus is identical with Li/garia 

 Stal ; there is nothing in the description by the author (Berlin, 

 eut. Zeitsch. 1891, p. 172) to distinguish it from the latter genus, 

 and the two species described are probably identical vdth some of 

 those described by Weise or myself under the generic name of 

 Lygaria. 



Chetsomela ifATALEXsis Vogel. 



Tsipingo (G. Marshall); Pine Town, Natal, Durban (my 

 collection). 



I refer specimens from the above localities to Vogel's species, but 

 not without some doubt, since this author's descriptions are in 

 mariy cases entirely inadequate for a certain recognition of the 

 many closely allied species. The present species is one of the most 

 convex-shaped Chn/somela; I know, and almost subglobular ; the 

 thorax has rather strongly obliquely narrowed sides and its anterior 

 margin is very deeply concave, the cUsc is iri-egularly impressed 

 with scattered and distinct punctures, the sides being as usual 

 more closely punctate ; the elytra are deeply punctured in partly 

 regular but mostly irregular rows, the punctures are round and of 

 violet colour, the lateral margins are broad, slightly raised and 

 entirely impunctate ; the elytral epipleurte are exceptionally broad, 

 as Vogel describes them : the general colour is uniformly brownish 

 seneous ; the underside is nearly black, finely and closely punctured ;
