XLV. — On new Species of Histeridre and Notices of others. 

 By G. Lewis, F.L.S. 



Marseul, in his Monograph, collated descriptions of species 

 other than his own for the sake of easy reference, and I have 

 from time to time followed his example. In this, the 

 thirty-second paper of the series, I have introduced a few 

 more.

Teretriosoma argentinum^ sp. n. 



Cylindricum, subelongatum, obscure ccneum, uiuliquo sat dense 

 punctulatum ; antcnuis pedibusque rufo-bruniicis ; elytris traus- 

 versim basi improssis ; mcsosterno stria marginal! prave integra ; 

 tibiis anticis 7-denticulatis. 



L. 2i mill. 



Cylindrical, somewhat elongate, faintly coppery, clearly 

 but not very closely punctured above ; the head sometimes 

 has a small fovea on its vertex which may be sexual ; the 

 thorax, the lateral stria continues behind the head; the 

 elytra are impressed transversely behind the anterior angles ; 

 the pygidium is slightly convex and with the propygidiura is 

 clearly punctulate like the upper surface ; the sterna are 

 microscopically strigose, with punctures evenly and not 

 closely set; the prosternal keel is arched at the base and 

 anteriorly the marginal rim is very narrow ; the mesosternum 

 is obtusely produced anteriorly and the marginal stria is 

 apparently complete but irregular, owing to tlie interposition 

 of punctures ; the metasternum has a well-marked lateral 

 stria which turn* outwards from the anterior edue ; the legs
