The ?ede:io-us is somewhat iutenuediate in structure between that 

 of Q. aftenuaf Its und Q.fidvicollis. The upper or larger lobe closely 

 resembles the same portion in Q. atteuaarus, but the lower lobe is 

 much broader and more like that of Q. fulviroUis. 



I have specimens of Q. piclpenidt: from G-arvie, Ross- shire ; Dal- 

 whinnie, Inverness-shire ; and Mount Brandon, Co. Kerry. 



As several Coleopterists have told me they have had difficulty in 

 identifying members of this group (Baphirus) of Quedius, I append 

 a table of the species. 



I. — Scutelliun smooth Q. auricomus, Kies. 



II. — Scutellimi punctured and pubescent. 



i. — Size larger, shape more fusiform ; head much lon<^er than broad ; first 

 joint of posterior tarsi much longer than last Q. rufipcs, Gv. 



ii. — Size smaller, shape less fiisiform ; liead broader ; first joint of posterioi 

 tarsi equal to or only slightly longer than last. 



1. — Elytra bright bronze or yellowish ; 2nd to 4th dorsal segments of 

 hind body with a dark velvety depressed patch on each side ; 

 first joint of posterior tarsi slightly longer than last... 



Q. scmiseneus, Steph. 



2. — Elytra duller, not yellowish ; hind body without dark velvety de- 

 pressed patches ; first joint of jjosterior tarsi not longer than 

 last. 

 A. — Antennae thickened towards apex, penultimate joints about as long as broad ; 

 head about as long as broad ; hind body very closely and evenly punc- 

 tured Q. attenuates, Gyll. 



B. — Antennaj not thickened towards apex, penultimate joints slightly longer 

 than broad ; head distinctly transverse. 



a. — Size larger ; basal segments of hind body very closely pimctured. 



a*. — Form subparallel ; head less transverse ; elytra shorter than thorax ; 



hind body more coarsely punctiired, apical segments not so closely 



as rest Q. picipennis, Heer. 



b*. — Form more fusiform ; head more transverse ; elytra about as long as 



thorax ; hind body evenly and less coarsely punctured... 



Q.fulvicollis, Steph. 

 h. — Size smaller ; hind body much less closely pvinctm-ed ; head strongly 



transverse Q. hoops, Gr.
