STAPHYLINID^. 



I believe that it is truly distinct ; though further material is mucl 

 required, in order to ascertain this positively. It seems to be more 

 piceous and shining than that insect, and less evidently sculptured 

 (or shagreened) when viewed beneath the microscope ; its elytra and 

 antennae are a little longer; and its head and prothorax are fre- 

 quently (though not always) brightly rufo-testaceous. From the 

 European C.fusculum its totally pallid antennae and comparatively 

 short feet will, apart from minor differences, at once separate it.

Habitat Maderenses (Mad.) et Canarienses (ins. omnes), plerumque 

 in intermediis. 



The European T. pusillus, though nowhere abundant, is widely 

 spread over these Atlantic Groups occurring beneath stones and 

 vegetable refuse, at intermediate elevations. It is found sparingly 

 in Madeira proper, for the most part within the sylvan districts ; and 

 I have myself captured it in all the Canarian islands, except Palma, 

 where however it was met with by Mr. Gray. Although unmistake- 

 ably separable from that species, its larger size, broader outline, and 

 darker hue seem nevertheless to be the only characters which dis- 

 tinguish it from the T. brunneus. 



1323. Tachyporus brunneus. 



Oxyporus brunneus, Fab., Ent. Syst. i. ii. 535 (1792).

Habitat Maderenses (in Ilheo CTiao sold haud observatus) et Cana- 

 rienses (in Fuert. sola adhuc non captus), vulgaris. 



There is scarcely any insect more widely diffused over these At- 

 lantic Groups than this common European Tachyporus. Indeed we 

 may be pretty sure that it is quite universal ; for it has already been 

 captured in tHe whole of the Madeiran islands except the northern 

 Deserta (or Ilheo Chao), and in all the Canarian ones except Euerte- 

 ventura ; in both of which, however, it must doubtless exist.
