The sculpture of the pronotum consists of a fairly distinct (but 

 not at all sharply defined) wide longitudinal impression — widest 

 and deepest near the base — on either side of the middle, which 

 (between the impressions) is somewhat strongly convex ; these 

 impressions are followed externally by another feeble convexity, 

 between which and the lateral margin is another longitudinal 

 impression, but this latter impression is scarcely traceable except 

 in the middle of its length. Thus the pronotum might also be 

 described as having three lonc(itudinal obtuse convexities, between 

 and outside which the surface is vaguely and unevenly 

 depressed.

A. Koebelei, sp. nov Ferrugiaeus, pronoti disco et abdominis 



lateribus infuscatis ; capite crebre sat leviter nullo modo 



subtiliter, prothorace minus crebre sat fortiter, elytris minus 



crebre sat profunde sat grosse, abdomine fere ut prothorax, 



punctulatis; capite utrinque longitudinaliter impresso et 



circum marginem liberum manifeste reflexo ; antennarum 



clava 3-articulata ; prothorace sat transverso, sulco longi- 



tudinali mediano instructo, angulis posticis perspicue (fere 



ut Megarthri depressi) emarginatis ; elytris quam prothorax 



fere sesquilongioribus. Long., 1 1.; lat., f 1. (vix). 



So unlike the preceding (//. rauciis) in most respects as to 



suggest hesitation about associating the two generically ; — but 



they agree in what seems to me the essential character that 



prevents their being placed in any of the old Proteinid genera, — 



i.e. the structure of the tarsi, and therefore I think are best left 



together for the present. The present species is much more like 



Megarthrus in facies than is the other, — especially in respect of 



its prothorax, — longitudinally uni-sulcate and having the hind 



corners very conspicuously emarginate.
