74 CLAVICOUNIA. [ 



2. Size smaller ; thorax longer than broad with 

 sides rounded and gradually narrowed iu 

 front. 



A. Antenna) with penullimate joints feebly 

 transverse; elytra with the four basal im- 

 pressions almost equally deep, the external 



ones elongate N. BUBICPNDUS, Schaum. 



B. Antennae with penultimate joints strongly 

 transverse ; elytra with external basal im- 

 pressions small and shallow N. CABIN ATUS, Muls. 



II. Forehead without fovea near eyes ; thorax without 



longitudinal keel before scutellum. 

 i. Colour lighter ; form more convex ; antennae less 



thickened towards apex ; transverse basal furrow 



of thorax with two fovem on each side near 



margins N. SPARBHALLI, Denny. 



ii. Colour darker ; form depressed ; antennae more 



thickened towards apex ; transverse basal furrow 



of thorax with one fovea on each side . . . . N. LONGICOLLIS, Mots. 



(prateritus, Rye). 



N. elonpratulus, Mull. Dark pitchy-red or reddish-black, shining, 

 antennro and legs reddish- testaceous, palpi and tarsi yellow ; somewhat 

 immature specimens are lighter ; head rather large, a little narrower 

 than thorax ; antennae rather long and stout, gradually thickened to 

 apex, with the penultimate joints distinctly transverse ; thorax rather 

 long with the sides rounded in front and almost parallel behind, more or 

 less distinctly punctured, depressed at base, with a fine keel above 

 scutellum, and two fovea? on each side ; elytra long oval, much broader 

 than thorax, finely and not thickly punctured, with two rather long 

 foveae at base, of which the inner one is the broadest and deepest ; 

 femora thickened at apex. L. If mm. 



In moss, &c. ; occasionally by evening sweeping ; not uncommon in some districts ; 

 London district, generally distributed ; Hastings ; Gosport ; Kiddlesdown ; Midland 

 districts, in most localities, Bewdley, Sherwood, Repton, Birmingham district, &c ; 

 it appears to become rarer further north ; Scotland, rare, Solway and Tay districts. 

 Ireland, Galway (J. J. Walker). 



N ang-ulatus, Mull, (impressus, Sahib. Wigltami, Denny). In 

 size, colour, and general appearance this species rather closely 

 resembles the preceding, but is very easily distinguished by the 

 shape and sculpture of the thorax, which is about as long as 

 broad, strongly angled on anterior third, abruptly contracted in front, 

 and gradually narrowed towards base in almost a straight line ; it is 

 impunctate, and strongly pubescent at sides, especially in front ; the 

 antennje, moreover, have the penultimate joints less transverse than in 

 N. clongatulus, the elytra have the sides a little less rounded, and are 

 more finely punctured ; the shoulders also are more marked, and the 

 femora are less dilated at apex. L. If- 1^.
