they have nevertheless engaged the attention of 

 various European Entomologists, and it may justly 

 be said that their metropolis is situate in the 

 Northern regions. This genus of Linneus included 

 only twenty-six species. It was early dismem- 

 bered by Fabricius, who constituted two other 

 genera, namely, Oxyporus and Paederus; other 

 writers have since successfully cut up the group, 

 and arranged them into families. The genera 

 known at present amount nearly to one hundred, 

 and the species in our cabinets greatly exceed a 

 thousand. Although much has been done in regard 

 to the European species, little attention has been 

 paid to exotics ; those of Asia, Africa, and America, 

 are comparatively unknown. It is to be hoped 

 that Gravenhorst and Erichson will, ere long, give 

 us their observations on the species belonging to 

 those countries which have hitherto been greatly 

 neglected. 



Linnean Species. 



Sp. 10. Lignorum. — I consider this insect as a 

 Tachyporus of Gravenhorst. 



Sp. 13. Flavescens. — Probably a Tachinus. The 

 Staphilinus Flavescens of Fabricius, must not be 

 confounded with this insect. Gravenhorst, whose 

 authority is very valuable, gives us the following 

 note on this species — " Stap. Flavescens, Linneus, 

 in Faun. Suec. No. 850 ; hue non pertinere videtur, 

 nam similis est Stap. subterraneo (Tachyporo sub- 

 terraneo) — Confer T. humeralis M. p. 137."
