new Species of lilsiaridx. 277 



Teretrius qiiadristriatus, sp. n. 



Cylindricus, niger, nitidus ; auteniiis pedibusque rufo -brunneis ; 



pronoto ante scufcellum grosse punctato ; prosterno utrinque 



bistriato ; tibiis anticis o-deatatis. 

 L. Ih mill. 



Cylindrical, black and shining, antennne and legs reddish 

 brown ; the head convex above, punctate, punctures some- 

 what coarse and least closely set along the neck ; the thorax is 

 similarly punctured anteriorly, but nearer the base, especially 

 before the scutellum, the punctures are much larger and oval, 

 the marginal stria is complete but very fine behind the head ; 

 the elytra are more finely punctured and the points are less 

 close in the median areas ; the pygidia are evenly not densely 

 punctured ; the prosternum is finely marginate and the sur- 

 face somewhat obscurely and rugosely punctate, the keel has 

 two strire on either side, the striae are joined at the base and 

 slightly and gradually diverge anteriorly, but the two inner 

 strioe are almost parallel to one another ; the mesosternum is 

 rather obtuse in the middle and marginate, surface, and that 

 of the metasternum also, is punctured but not closely ; the 

 anterior tibias are 5-dentate. 



Teretrius mozambicus, Mars., is slightly larger than this 

 species and similar in outline. The prosternal stria3 are 

 different to those of any other described species. 



IJab. Salisbury, Mashonaland (Gut/ A. K. Marshall). 



Teretrius indus, sp. n. 



Cylindricus, subelongatus, brunneo-piceus, antennis pedibusque rufo- 

 brunneis, undique punctulatus ; prosterno lato, striis anticis 

 paululum divergeutibus ; mesosterno in medio obtuse prominulo, 

 marginate; propygidio parum couvexo; tibiis anticis 5-6-deutatis. 



L. 2i mill. 



Cylindrical, rather elongate, pitchy brown and shining, 

 wholly but not densely punctulate ; the head is a little 

 convex between the eyes ; the thorax narrowest anteriorly, 

 marginal stria complete, but extremely fine behind the head ; 

 the elytra also are not quite parallel laterally, and the smooth 

 space below the shoulder, usually a little raised in this genus, 

 is flat ; the prosternum has a broad keel and the stria3 are 

 wide apax't and diverge slightly in front, the anterior lobe is 

 distinctly marginate both laterally and along its anterior 

 edge ; tlie mesosternum is marginate anteriorly and obtusely 

 acuminate; the surfaces of the sterna and the first segment 

 of the abdomen are somewhat sparingly punctulate ; the 

 anterior tibiae are 5-6-dentate.
