new Species of V{\s\cri(\9C. 191 



rally bistriate ; the tibiae rather narrow, anterior tliighs 

 grooved for their whole length to receive the tibije *, tarsal 

 groove open exteriorly, tarsi short and rather stout, with 

 two claws. 



Coproxenus }[arslialh\ sp. n. 



Brevitcr ovatus, parum convexus, obscure rufo-brunneus, nitidus ; 

 capite punctulato, stria intej^ra ; elytris ulrinque bicarinatis, striis 

 1-4 et suturali integris, 5 basi abbreviata ; prostcrno bistriato, 

 interstitio parum lato. 



L. 3 mill. 



Shortly oval, little convex, obscure reddish brown, shining; 

 the head, frontal stria complete, strong in the ocular region, 

 feebler in front, not closely punctured, but the surface has a 

 microscopic sculpture, slightly impressed anteriorly ; the 

 thorax sculptured like the head, stria complete and continuing 

 in front, anterior angles a little prominent, obtuse, and a 

 little raised within ; the elytra, margin (equivalent of sub- 

 humeral external stria) carinate, carina not so robust as that 

 of C. opacipe7i7iiSj and within, the channel is smooth and even 

 (without bosses) ; the next carina is complete, with a rough- 

 ened edge ; striai formed as in C. opacipennis, but less distinct, 

 owing to the interstices being convex and somewhat closely 

 punctulate; the propygidium is clearly and not closely punc- 

 tulate, the punctuation of the pygidium is less distinct ; the 

 prosternum with a microscopic surface strigosity and a few 

 large punctures on the anterior lobe, keel rather wide, with 4 

 or 5 punctures set quite irregularly, bistriate, strias straight, 

 leaning to each other from the base and meeting anteriorly ; 

 the mesosternum, strias complete, leaving a somewhat raised 

 margin which has an ill-detined stria on either side ; the trans- 

 verse stria is roughly crenulate and bowed ; the metasternum 

 is strongly bistriate at the sides and the interstices are wide ; 

 the inner stria meets the mesosternal transverse stria, surface 

 with large irregular punctures cliiefly distributed in the middle 

 of the ])late on either side of a longitudinal median line ; the 

 first segment of the abdomen has a wide lateral stria and 

 similar punctures to those on the metasternum, but on the 

 anterior edge the points are regular and in a row. 



I have much pleasure in naming this very curious species 

 after Mr. Guy A. K. Marshall, who is the lirst entomologist 

 who has sent home any considerable collection of Histeridse 

 from South Africa accompanied with notes on their habits. 



Hab. Natal (no. 3598). " Taken in cow-dung " (Marshall) . 



* This character exists iu Pelorurus, but is not noticed by Marseul.
