This species may be placed near II. vilis, Mars., and 

 scabripygus, Sell. 



Hah. Salisbury, Mashonaland {Guy A. K. Marshall, 

 Nov. 1900). 



It is a stercoraceous species. 



Hister honestus, sp. n. 



Ovalis, convexiusculus, nigcr, nitidus ; elytris rubris, macula 

 scutellari nigra ; fronte stria transversa arcuata ; pronoto stria 

 laterali interna pone oculos derlexa : elytris striis dorsalibus 

 integris, 5-G basi conjunctis ; mesosterno antiee sinuato ; tibiis 

 anticis 3-dentatis. 



L. 2§ mill. 



Oval, rather convex, black and shining ; the head, stria 

 complete and transversely bowed ; the thorax, marginal stria 

 tine and complete, outer lateral touches the base and ceases 

 behind the eye, interstice between it and the inner lateral 

 rather wide and widest anteriorly, inner lateral complete, 

 sinuous before the base and deflected behind the eye ; the 

 elytra somewhat obscurely reddish, with the scutellar region 

 and the disk blackish, stria?, humeral short, bent, not touching 

 the base nor quite reaching the middle, dorsal 1-4 complete, 

 5-6 also complete and joining at the base; the pygidia 

 coarsely, clearly, and not closely punctured ; the prosternum 

 is microscopically strigous, anterior lobe strongly marginate, 

 keel without striae ; the mesosternum is feebly sinuous ante- 

 riorly and the marginal stria is somewhat crenate, very slightly 

 bent in the middle, and is not quite close to the edge. 



This species is exceedingly similar to //. castus, Lew., but 

 the mesosternum is not arcuate in outline nor does the 

 marginal stria follow so closely to the edge. In honestus the 

 inner thoracic lateral stria is deflected behind the eye and the 

 outer stria reaches the base. In castus the outer stria is 

 usually shortened at the base and in some examples the fifth 

 dorsal stria is sometimes slightly broken.

Hister bahiensis, sp. n. 



Ovatus, convexus, niger, nitidus ; fronte stria semicirculari ; pro- 

 noto stria marginali post oculos interrupta, stria laterali interna 

 integra ; elytris striis 1-3 integris, 4 et suturali dimidiatis, 5 

 brevissima ; propygidio utrinque foveolato ; mesosterno in medio 

 sinuato, stria marginali tenuiter impressa ; tibiis anticis 5-dcntieu- 

 latis.
