new Species of Histeridse. 179 



Oval, convex, black, shining ; the head finely punctulate, 

 lateral stria ceasing in front of the eye ; the thorax distinctly 

 punctulate throughout, punctures larger than those on the 

 head, impressed before the scutellum with a cluster of some- 

 what larger punctures, marginal stria fine and complete, 

 but not visible at the sides when viewed from above ; the 

 elytra, stria? 1-4 and sutural complete, fifth punctiform and 

 evanescent towards the base, interstices punctulate but less 

 distinctly on the disk than nearer the margins ; the propy- 

 gidium and pygidium distinctly and somewhat closely punc- 

 tulate ; the prosternum bistriate, stria? not meeting before or 

 behind, feebly sinuous at the coxas, keel distinctly but not 

 closely punctulate ; the mesosternum almost straight ante- 

 riorly, marginal stria fine and complete, transverse stria 

 equally fine and minutely crenulate, surface punctulate like 

 the keel of the prosternum. 



This species is similar to Phelister truncatus, Sch., but it 

 is larger and easily distinguished by the punctuation of the 

 elytra. 



Hab. Cape of Good Hope {Lightfoot) . 



The following isolated description is introduced here for 

 the sake of easy reference, and because it appears to me to 

 refer to P. Raffrayi, mihi, 1879. The colour of the species 

 in this genus is, as a rule, remarkably constant, but it cannot 

 be always relied on as a specific character.
