190 Mr. G. Lewis on 



The late Mr. Julius Flohr, 1 believe, left his collections to 

 the National Museum in Berlin, and therefore I presume 

 there is an exam pie of this species there. But on some occasions 

 Mr. Flohr kindly gave me his unique specimens. 



Hister ruhricatus^ sp. n. 



Late ovalis, convexiusculus, nitidus, elj'tris apiealibus late rufis ; 

 fronte stria iiitegra medio retro-acuminata ; pronoto bifoveo]ato, 

 stria lateral! basi abbreviata ; elytris striis 1-5 integris, suturali 

 ante medium abbreviata. 



L. 3j mill. 



Oval, little convex, black, with the apical portion of the 

 elytra broadly red ; the head, frontal stria complete and in 

 the middle drawn back to a sharp point ; the thorax with a 

 fovea and stria like those of H. himaculatus, L., but the 

 latter is more abbreviated ; the elytra, striai 1-5 complete, also 

 internal subhumeral, sutural apical and occupying two thirds 

 of the elytral length, the fifth stria at the base turns towards 

 the scutelluin much more conspicuously than the corresponding 

 stria in H. himaculatus ; the propygldium and pygidium have 

 a few scattered and fine punctures ; the sternal plates are 

 much wider than those of ZT. himaculatus, otherwise they are 

 similar. The anterior tibia has one large and wide apical 

 tooth and four little ones behind it. 



The great differences between this and the Linnean species 

 himaculatus lie in its short and broad-oval form, the form of 

 the frontal stria, and the more markedly inturned fifth dorsal 

 stria. 



Hah. Cameroon. 



COPROXENUS, gen. nov. 



Body rather convex, broadly or shortly oval ; head small, 

 retractile, forehead impressed, clypeus transverse, mandibles 

 equal and dentate; antenna, the club is oval and its fossa 

 deep and in the anterior angle ; the thorax is transverse, at 

 the sides narrowing from the hind to the fore angle ; the 

 scutellum small and triangular ; the elytra strongly carinate 

 on the lateral edge (this carina takes the place of the usual 

 external subhumeral stria), the internal subhumeral is also sub- 

 stituted by a carina less strong ; the dorsal stria3 are strong, 

 and, in the two species known, complete, except the fittii ; 

 the pygidia are formed like those in Felorurus ; the proster- 

 num is incised at the base, keel more or less wide, bistriate ; 

 the mesosternum anteriorly acuminate, with a strong marginal 

 stria and a transverse crenulate one ; the metasternum late-
