12 ADEPHAGx\. [Nofiophilus. 



N. Bubstrlatus, Viat. (bif/utfafus, var. y., Daws.). Resembles the 

 preceding, but is smaller and narrower with the punctuation much feebler, 

 the punctured striee being sometimes nearly obsolete, or even entirely 

 obliterated before apex ; the interstices between the suture and the 

 first, and between the second and seventh striae are exceedingly finely 

 shagreened, which gives an opaqueness to those parts contrasting strongly 

 with the broad glabrous space between the first and second striae ; 

 the colour invariably is lighter and more brassy. L. 4 mm. 



Local, but widely distributed, and probably very often overlooked ; Croydon and 

 otber places in tbe London district ; Deal; Kepton; Lincoln; Devonshire; Scotland, 

 local Lowlands, Kircaldy, &c. 



N. quadrig'uttatus, Dej. Resembles N. hujuttatiis, oi vftiich it 

 is commonly considered to be a variety, but differs by having two pores 

 on the middle third of the elytra instead of one, placed near one another ; 

 this, however, is not always a constant distinction, for specimens have 

 been recorded which have two jwres on one side and one on the other ; 

 the thorax, however, has the sides almost straight to base, and is more 

 strongly sculptured than in N. bigidtatiis, which has the sides of the 

 thorax more or less plainly sinuate. L. 4^ mm. 



Rare. Sandy places. West Wickham ; Tunbridge Wells ; Redbill ; Reigato. 



It is yet a question whether this may not be an uncommon variety oi N. bigultatus, 

 as the latter has the thorax rather variable in shape ; it seems, however, to have as 

 good a claim to specific rank as N. suhstriatus. 



N. aquaticus, L. Brassy, occasionally dark bluish-black ; an- 

 tenna3 black with basal joints red beneath ; thorax broadest in front 

 with sides very slightly rounded and sinuate ; elytra oblong, much wider 

 than thorax, sides somewhat parallel ; striae well marked, gradually be- 

 coming feebler behind middle, two only being carried to apex ; between 

 the third and fourth there is a deep pore a little before middle, and 

 there is also a smaller one at apex. Legs entirely dark bronze. L. 

 4| mm. 



Common and widely distributed. 



N. palustris, Duft. Closely resembles the preceding, with which 

 it was united by Gyllenhal and Dejean ; it is, however, shorter and 

 narrower ; the antennce have the three basal joints entirely testaceous ; 

 the thorax is shorter with the sides more rounded in front and more 

 contracted behind, and the lateral margins and base less depressed ; the 

 elytra are shorter and very distinctly narrowed in front, and the tibiis are 

 testaceous. L. 4 mm. 



Rather local, though by no means uncommon in England ; local in Scotland, 

 Lowlands ; Ireland, common near Dublin. Usually common where it occurs. 



N. rufipes, Curt. Rather more coppery than the other species of 

 the genus ; thorax rather strongly contracted behind ; elytra very smooth, 

 slightly ochreous and dull at apex ; stria? of elytra well marked, 

 continued to apex ; between the second and third strite there is a deep
