five) punctures down either side of their prothoracic disk, will 

 at once distinguish them from the rest of the Madeiran Philonthi. 

 In more northern latitudes, the species generally occurs about 

 hotbeds, — under which circumstances it was discovered by M. 

 Rouzet in Paris ; and I have myself taken it in similar positions 

 in England.

Genus Scop^us. 



Erichson, Gen. et Spec. Staph. 604 (1839). 



Scopceus subopacusj n. sp. 



S. angustus, nigro-piceus, subopacus ; capite prothoraceque dense 

 alutaceis, fere pilis carentibus, illo subrotundato-quadrato ; elytris 

 dense et minute punctulatis et pilis brevibus demissis cinereis 

 vestitis ; antennis rufo-testaceis, apicem versus fuscescentibus ; 

 pedibus infuscato-testaceis.

S. narrow, blackish -piceous, and nearly opake. Head and 

 prothorax densely alutaceous, but scarcely punctured, and almost 

 free from pile : the former roundish-quadrate (being truncated 

 behind, but not very abruptly so), and with the eyes rounded, 

 and rather small : the latter oblong, and rather acuminated in 

 front. Elytra closely and minutely punctulated all over, and 

 (together with the abdomen) more evidently pilose than the 

 head and prothorax — being clothed with a fine and very short, 

 decumbent, cinereous pubescence. Abdomen concolorous, even 

 the extreme apex being scarcely more diluted in colouring than 

 the rest of the surface. Antenna reddish-testaceous at their 

 base, but browner towards their apex. Legs brownish-testaceous, 

 being unequally infuscated all over. 



The unique example from which the above description has 

 been compiled was detected by Mr. Bewicke, who captured it 

 (along with the last species) beneath hay-stack refuse at S. An- 

 tonio da Serra, during the summer of 1859. It has much the 

 appearance of a small dark Lithocharis ; but the generic cha- 

 racters of Scopaus, which mainly consist in its more robust legs 

 (especially the anterior pair) and its small tricuspid corneous 

 ligula, will, apart from the diminished bulk of the species which 

 compose the group, readily distinguish it. Judging from the 

 description, it seems somewhat allied (particularly in its opake 

 surface) to the L. infirmus, Erichs., from Egypt ; nevertheless 

 its uniformly dark hue and the densely alutaceous (but appa- 

 rently unpunctured) sculpture of its head and prothorax are of 

 themselves sufficient to separate it therefrom.
