INSECTA MADERENSIA. 103 



80. Cercyon inquinatum, WbU. 

 C. i-otundato-oblongum convexum nigrum nitidissimum, prothorace plus minusve subpicescenti, elytris 



profunde subcrenato-striatis, pedibus rufo-fen-ugineis. 

 Long. Corp. lin. 1t-1|. 



Habitat Maderam australem, a Dom. Rousset ab ovk Funchalensi maritima nuper communicatum. 



C. roundisli-oblong, convex, black, and exceedingly shining ; most delicately, but not veiy closely 

 punctulated all over (the punctures appearing, under the microscope, smaller and more remote 

 than those of any of the other species). Prothorax more or less perceptibly picescent, especially 

 at the margins. Elytra deeply crenate- (scarcely punctate-) striated, particularly behind ; and 

 ^^•ith slight indications of a cm-ved, or lunate, portion a little behind the apex, and common to 

 both, dull rufescent or infuscate. Antmnm at base, and the jialpi, rufo-testaceous ; the former 

 with the club (which is more elongated than in the other species) infuscate. Legs rufo- 

 ferraginous, or rufo-piceous. 



An exceedingly distinct species, and one which may be readily known fi-om the 

 rest of the Cercya here described by its larger, somewhat rounder, and more highly 

 poHshed body, by its elj^tra being more evidently cme«ife-striated, and by the 

 comparatively elongated club of its antennje. It 'is moreover of a darker hue,— 

 the tendency of its prothorax to become picescent being at times so slight as to 

 be scarcely perceptible; whilst the obscui-e sublimate portion, or patch, towards the 

 apex of its elytra is, likewise, occasionally nearly obsolete. It is an insect which 

 entii-ely escaped my own observations in the Madeu-a Islands, the only specimens 

 which I have seen having been lately commimicated by M. Eousset, who captui-ed 

 them on the sea-beach at Eunchal. It recedes from all the Em-opean members of 

 the genus with which I am acquainted, but is more aUied perhaps to the common 

 C.flavipes than to any other;— fi-om which nevertheless its differently colovu-ed, 

 less punctiu-ed, and more shining surface, added to its crenate-striated elytra, wUl 

 be sufficient, apart from minor characteristics, at once to remove it. 



81. Cercyon fimetarium, Woll. 

 C. obovatum (postice acuminatum) convexum nigrum subnitidum distincte punctulatum, elytris 



profunde punctato-striatis ad apicem late testaceis, pedibus pallido-ferrugineis. 

 Long, corp.liu. 1. 



Habitat Maderam, in stercore bovino ubique vulgaris, ab ora maritime fere ad cacumina montium 

 ascendens. 



C. obovate (being somewhat acuminated behind), convex, black, and but slightly shining ; rather 

 closely and distinctly punctulated all over. Pruthorax concolorous, the margins having no 

 tendency to be paler. Ebjtra deeply punctate-striated ; with the apex, and more or less of the 

 lateral edges, broadly and brightly testaceous. Antenna at base, and the palpi testaceous ; the 

 former with the club, and the latter more or less in parts, infuscate. Legs pale ferruginous.
