Fam. Carabid.39. 

 Genus APOTOMUS. 



(Hoffm.) lUiger, Mag. fur lus. vi. 348 (1807). 

 Apotomus Chaudoirii. 



A. rufo-ferrugiueus, dense pubescens, capite prothoraceque nitidis- 

 simis ; elytris profunde punctato-striatis ; antennis, palpis pedi- 

 busque pallido-testaceis, antennarum articulis quinto, sexto et 

 septimo nigrescentibus.

Habitat sub lapidibus in locis maritimis Maderee et Portus Sancti 

 tempore vernali, passim. 



Although I can scarcely persuade myself that the Madeiran 

 Apotomus is anything more than a geographical state of the 

 Mediterranean A. rufus (to which I have hitherto referred it), I 

 am nevertheless induced to separate it therefrom on the high 

 authority of the Baron Maximilian de Chaudoir, who has lately 

 informed me that he considers it specifically distinct; and I 

 feel the more bound to do this on account of the great attention 

 wbich he had paid for many years to the Carabida. I have 

 therefore much pleasure in dedicating it to him. It seems to 

 differ from the ordinary European form in the much paler 

 colour of its antennae, palpi, and legs, the first of which, more- 

 over, have their fifth, sixth, and seventh joints very much darker 

 than the remainder, the basal four and apical four being al- 

 ways pale. The Baron Chaudoir also pointed to some differ- 

 ence in the pubescence ; but, on comparing the Madeiran ex- 

 amples with specimens which I possess from the south of France 

 and Corfu, I cannot detect anything peculiar in this respect. 



Genus Z ARGUS. 



Wollaston, Ins. Mad. 22, tab. i. f. 4, 5, 6 (1854).

 versus fusco-piceis.
