CANARIAN COLEOPTERA. 503 



Genus 317. aUEDIUS. 



(Leach) Steph., ///. Brit. Ent. v. 215 (1832). 



§ I. Oculi niinoi-es. Antennce, pedesque rohusti, tarsis anticis 

 latissime dilatatis. 



855. Guedius angustifrons, n. sp. 

 Q. cajjite (angusto) prothorace(|ue nigris, subnitidis ; elytris abdomi- 

 neque piibescentibus, illis brevibus subruguloso-puuctatis rufo- 

 piceis, hoc iiigro-piceo postice paulo dilutiore, profuude sed parce 

 punctato ; antennis (articulo ultimo oblique subtruncato) fuscis, ad 

 basin pedibusque piceo-testaceis. — Long. corp. lin. 5. 



Habitat in intermediis Canarise et Gomerse, rarissimus. 



The less highly polished head and prothorax (the former of which 

 is narrow and oval, with the eyes not at aU prominent), in conjunc- 

 tion with its relatively shorter and more rufescent elytra, will at once 

 distinguish this Quedius fr. m the two following ones. It is appa- 

 rently extremely rare, and confined to damp spots (particularly sylvan 

 and subsylvan ones) of intermediate elevations. I have captured it, 

 beneath wet moss, near Teror in Grand Canary ; and a single example 

 was taken by Dr. Crotch (I believe, above Hermigua) in Gomera. 



856. Quedius fulgidus. 

 Q. ater, interdum elytris abdominisque apice picescentioribus ; capite 

 (crasso) prothoraceque pernitidis ; elytris subconvexis, sat parce 

 subruguloso-punctatis ; abdomine dense subasperato-punctulato ; 

 antennis (articulo ultimo acuminato-ovato) pedibusque valde in- 

 crassatis, nigro-piceis, illis basi nigro-variegatis. — Long. corp. lin. 

 4-5i 



Staphylinus fulgidus, Fab., Mant. Ins. i. 220 (1787). 



variabilis, Gt/IL, Ins. Snoc. ii. 303 (1810). 



Quedius fulgidus, Erich., Gen. et Spec. Staph. 52.5 (1839). 

 , Kraatz, Nat. der Ins. Deutsch. ii. 492 (185G). 



Habitat in intermediis Teneriffae et Gomerae, rarissimus. 



I can see nothing in the Canarian examples of this insect to war- 

 rant the suspicion that they are distinct from the common European 

 Q. fulgidus. The species may immediately be known from the other 

 Quedii here enumerated by its larger size, more robust form, and 

 blacker hue, by its more sparingly punctured elytra (which vary from 

 intense black to rufo-piceous), and by its very much thicker limbs. 

 Like the Q. angustifrons, it is decidedly rare in these islands. I 

 have taken it at Las Mercedes in Teneriffe, and it was captured in 

 both Teneriffe and Gomera by Dr. Crotch.
