new Species of HiateriJjB. 105 



This is the third species of the genus known. 

 IJab. The Matopo Mountains, Matabeleland {Guy A. K. 

 Marshall) . 



Reninus Salvint, Lew., occurs in the nests of (Ecodoma 

 cejyhalotes, and it is probable that all the species of the genus 

 llenitius nud Discoceiis are formicicolous. Epiglyptus (Ilister) 

 costatus, Mars., also associates with the CEcodoma. 



Reninus puncticollis, sp. n. 



Breviter ovatus, convexiis, niger, nitidus ; fronte depressa, stria 

 aiigulata ; pronoto punctate (basi excepta) ; elj-tris striis sub • 

 humerali et 1 dorsali integris, 1-3 postice, 5 et suturali totis 

 punctiformibus ; tibiis extus valde dilatatis, 



L. ^-^ mill. 



Shortly oval, convex, black and shining ; the head, frontal 

 stria strong and angulate before the eyes, depressed before 

 the epistoraa, surface with bowed striae representing inconi- 

 ])lete parts of shallow punctures and set very irregularly ; 

 the thorax, marginal stria very fine and apparently very 

 narrowly interrupted behind the middle of the neck, the inner 

 stria is close to the marginal stria and traceable anteriorly to 

 a point behind the eye, anterior angles obtuse and reddish, 

 surface with coarse punctures, points most dense on the outer 

 part, and the scutellar region is smooth, the basal edge is 

 narrowly and microscopically strigose ; the elytra, striae, inner 

 humeral and first dorsal are complete and somewhat carinate 

 on the basal part, 1-3 are abbreviated on or before the middle, 

 but are continued apically by shallow punctures arranged 

 more or less in two rows, the fourth stria is hamate at the 

 base, 5 and sutural are indicated by shallow punctures, the 

 fifth is shortened at the middle, tlie sutural continues to the 

 base; the pygidia have a shallow sculpture, consisting appa- 

 rently of crescents or half punctures whicli have an imbricate 

 outline ; the presternum, lobe somewhat truncate anteriorly 

 and rather strongly marginate, with a few irregular and 

 shallow punctures, surface microscopically strigose, keel 

 bistriate, striae join anteriorly before reaching the suture, the 

 inner stria is abbreviated behind and the interstices of the 

 striae are smooth, the anterior area of the keel has a few 

 irregular punctures somewhat like those of the lobe ; the 

 mesosternum, marginal stria very fine, sinuous in the middle, 

 and not very close to the edge, from each basal angle pKO- 

 ceeds a fine bowed stria, unconnected with the lateral striae, 

 and both ends of them turn outwards, the sides are bistriate.
