}i;i(l ample groniuls for describing them as distinct species. 

 Its nearest allies amongst the South- African fauna known 

 to me arc C. liurbuucnsis, m., and C. reic/tei, did. 



Chhenius c/arksoni, sp. n. 



Length 1!) mm. ((^)-21? ( ? ) mm.; width 8.{-l) mm. 



Thorax length o-jI mm. ; width 0.^-7^ mm. 



Apterous ; head, prothorax, and elytra reddish to glowing 

 e()p[)ery bronze with vivid green reHeetions in strong lights ; 

 epistome. labrnm, mandibles, palpi^ and first three joints of 

 antenna; piccons ; apices of palpi, labrnm, and remaining 

 joints of antenn;e reddish. 



Legs and beneath black, very shiny. Head densely 

 coriaceonsly wrinkled and irregularly longitndinally plicate 

 on either side ; epistome and labrnm smooth, shiny. 



Prothorax subtrapczoid but with a little sinnation above 

 the posterior angles, apex bisinuate, frontal angles projecting 

 l)ut not sharp ; sides margined, gently ronudcd to abont 

 middle, thence, except for a slight sinnation above the 

 posterior angles, straight to base ; base shallowly emargi- 

 nate, disc convex, very declivous frontally, coriaceonsly 

 wrinkled, median groove and subbasal fovea? moderately 

 ilt'e[) and very shallowly connected by a subbasal depression. 



Elytra hardly wider thau prothorax at base, humeral 

 angle slightly projecting beneath it, sides nearly straight 

 in male and a little more ampliate in female, broadly 

 rounded to and very slightly sinuate above apex, convex, 

 strife moderately deep and wide, not or barely perceptibly 

 punctate (puncturatiim is faintly indicated in some examples 

 l)y faint spaced pia-pricks), intervals raised and very finely 

 shagreciied, nearly smooth. 



Underside : pro-, nieso-, and metasterna smooth save for a 

 few shallow transverse plications, the episterna densely, 

 rugosely aciculate-punctate ; abdomen very finely wrinkled 

 with roiigli plications laterally, the metepisterna, segments 

 of venter laterally, and intermediate femora with some 

 scattered pores bearing long red setae (in unrubbed 

 specimens). 



Very nearly allied to Chlcenius chinu, did., to which it is 

 similar in size and shape, and which also appears to be 

 wingless. Apart from its bright metallic coloration, not a 

 trace of which is observable in chum, it differs from it in 

 the following points. Antennai shorter (especially notice- 

 able in the respective males), a little more compressed 

 and more slender at bases of articles. Ihc sculpture
