Hob. Nyassa. 



Tlie head and the sides and disk of the prothorax are 

 sparsely but distinctly punctured. There are really five 

 tubercles on the latter, but the two postero-lateral are very 

 feeble and scarcely noticeable ; the median tubercle is the 

 most distinct. The nearly black transverse patch at the base 

 of the elytra is broadest along the suture, and gradually 

 narrows towards the sides, where it stops short just above the 

 shoulder ; it has a faintly granular and somewhat velvety 

 appearance. The remainder of the elytra has a scattered 

 brownish tawny pubescence and is somewhat strongly and 

 irregularly punctured, the punctures being especially visible 

 on those spots where the black and shiny derm is almost bare 

 of pubescence. The apices rounded. 



It is doubtful whether this species should not rather enter 

 into the genus Loplwptera^ with which it agrees in the sharp 

 and faintly toothed shoulders and in the crested base of the 

 elytra. The crest in the present species is, however, very 

 feeble, and consists of a row of three or four granules, of 

 which the most anterior and strongest forms a small vertical 

 ridge on the deflexed portion of the base. On the whole the 

 species can scarcely, I think, be separated from the genus 

 Monohamrims, and amongst described species comes nearest 

 perhaps in structural characters to M. Thomsoni, Chevr.

Niger, nitidus ; capitis fronte et scapo antennarum rugoso-granu- 

 losis, capitis vertice et lateribus punctatis ; prothoracis disco 

 leviter rugoso ; elytris basi albo bipunctatis, leviter rugulosis, 

 deinde punctatis, punctis evanescentibus versus apieem ; apicibus 

 singulatim rotundatis, nee dentatis.

Hah. South or Central America. 



A very distinct species, easily recognized by the almost 

 en tire absence of pubescence and by the presence of two small 

 white pubescent spots, one on the depressed basal portion of 

 eacli elytron a little removed from the scutellum, the latter 

 also bearing traces of a white pubescence behind. Another
