280 Mr. G. Lewis on 



interstices distinctly punctulate, 4 much less in width, apical 

 and dimidiate, 5 represented by a short apical line or puncture, 

 sutural shortened a little before the apex, extending just 

 beyond the middle and slightly turning from the suture at 

 either end ; the propygidium and pygidium are wholly and 

 coarsely punctured, but without impressions ; the prosternum, 

 the lobe is partly punctured and has a bordering stria, which 

 is close to the edge at the apex ; the mesosternum is very 

 feebly sinuous anteriorly and the marginal stria is complete ; 

 the anterior tibige are punctured and 3-dentate. 



This species belongs to the H. longicollis, Mars., group.

Hister zambesius, sp. n. 



Ovalis, convexus, niger, nitidus ; fronte irnpunctata, stria integra ; 

 pronoto lateribus bistriato ; elytris striis 1-4 integris, 5 basi 

 abbreviata, suturali vix abbreviata ; propygidio pygidioque dense 

 punctatis ; tibiis antieis 3-dentatis. 



L. 7-7j mill. 



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

 strong and complete, anteriorly nearly straight, labrum trans- 

 verse, mandibles impunctate; the thorax, marginal stria 

 very fine, outer lateral stria terminates after passing the 

 anterior angle, feebly sinuous in the middle, outer interstice 

 impunctate, inner lateral straight and continued behind the 

 head, interstice roughly punctate behind the anterior angle 

 and there is a small cluster of punctures anteriorly just within 

 the inner thoracic stria, the scutellar fovea is tine and linear ; 

 the elytra, striae, outer humeral is represented by a very short 

 median sulcus, inner humeral is complete, oblique basal 

 inconspicuous, 1-4 dorsal complete, somewhat wide, with all 

 the interstices more or less irregularly punctured, especially 

 near the apices, 5 stria is straight and shortened before the 

 base, sutural is bent and a little longer ; the propygidium 

 and pygidium are evenly and closely punctured, both are 

 without impressions; the sterna resemble those in the last 

 species ; the anterior tibige are 3-dentate. 



This, like the last species, also belongs to the B. longi- 

 collis group.
