II. Thorax and elytra dark blue. 



i. Legs blnck N. VIOLACKA, L. 



ii. Legs red N. KUFIPBS, De O. 



V. rnficollis, F. Oblong, shining, clothed with long villose 

 pubescence ; head bluish-black, antennae black with base reddish, 

 thorax and base of elytra and legs bright red, elytra, except base, 

 cyaneous, abdomen black ; head and thorax finely punctured, the 

 former rather large, with eyes prominent; the latter almost as long as 

 broad, with sides rounded, posterior angles obtuse; elytra depressed, 

 considerably broader than thorax, slightly widened behind, with very 

 fine punctured striae, interstices very broad, regularly and finely, but 

 distinctly, punctured. L. 4^-5 mm.

 very abundant ; London district, common ; Broadstairs ; Dover ; Lowestoft ;

 Repton ; Sherwood Forest ; Manchester ; Northumberland and Durham district ;

N. violacea, L. Smaller than the preceding, entirely cyaneous, 

 with the antennae and legs black ; it may also be distinguished both 

 from this and the following species by the strong rows of punctures on 

 the elytra, which become feebler towards apex ; the interstices are 

 narrow, and are very finely punctured; the upper surface is rather 

 sparingly clothed with blackish villose pubescence ; the elytra are 

 rather more convex than in N. ruficollis, and are somewhat uneven. 

 L. 3|-4 mm.

 Moray districts ; Ireland, near Dublin. 



N. rufipes, De G. (Agonolia niftpes, Muls.). Very like the pre- 

 ceding, but easily distinguished by the entirely red legs and red base of 

 antennae, and also by the much finer punctuation of the elytra, which 

 rather resembles that of N. ruficollis, but is somewhat stronger ; the 

 thorax is more transverse than in N. violacea, and the elytra more even ; 

 the pubescence on the elytra is shorter and on the thorax longer, the 

 difference being rather more marked than in either of the other two 

 species. L. 3-4 mm.
