94 ADEPHAGA. [_EurophiI/i.<f. 



base with a deep smooth fovea on each side ; elytra wider than the 

 thorax, much narrower and more parallel than in A. fuliginosus or micans, 

 shoulder-angles projecting, with very fine strice ; legs brownish testaceous. 

 L. 6-6 1 mm. 



Damp and marshy places; also uuder bark of fallen trees; local ; rather rare in the 

 London district ; common in the Midlands ; Yorkshire ; Northumberland and 

 Durham ; Scotland, local, Lowlands ; Ireland, near Belfast, Dublin, and Armagh. 



Besides other points of distinction, the subquadrate thorax, which has 

 the anterior and posterior margins almost equal in breadth, will serve at 

 once to separate this species from all its allies : from A. fuliijinosus it is 

 also distinguished by its more slender form, and more parallel elytra, 

 which are much more finely striated. 



A. Thoreyi, Dej. Elongate ; head and thorax pitchy, elytra 

 brownish-yellow, or light pitchy brown, darker in the middle next suture ; 

 antennoe pitchy, base reddish ; thorax with the margins often narrowly 

 testaceous, with sides rounded in front and contracted beliind, dis- 

 tinctly longer than broad, posterior angles rounded but visible, dorsal 

 furrow distinct, base Avith a small, rather shallow fovea on each side near 

 angles ; elytra with sides nearly parallel, about twice the width of the 

 base of thorax, finely striated ; femora except apex red, tibiae and tarsi 

 brownish. L. 7 mm. 



Marshy places beneath debris of reeds, &c. ; local, but not uncommon ; Kent; 

 Brighton ; Hastings ; Walton-on-Naze ; Burton-on-Trent ; Coleshill ; Sutton Park, 

 Birmingham ; Yorkshire ; Cambridgeshire Fens ; not recorded from the north of 

 England, Scotland, or L'eland. 



A. puellus, Dej. (pelidniis, Payk.). This species is so exceedingly 

 closely related to the preceding that the one might with very good 

 reason be considered a variety of the other ; in fact it is most probable 

 that this will eventually be the case : the only real difference seems to 

 lie in the colour, Avhich in A. pwUus is always dark pitchy black ; the 

 elytra are said to have their sides rather more rounded than in A. 

 Thoreyi, and to be more deeply striated (Daws., G. D. 94) ; on the other 

 hand, Schaum (Insect. Deutsch. i. 428) says distinctly of A. Thoreyi 

 that the striae, especially the outer ones, are a little stronger tlian in 

 A. pelidnus (ein wenig starker als bei pelidnus) : these difierences, there- 

 fore, ai'e evidently very small. L. 7 mm. 



Marshy places, at roots, beneath debris of rushes, kc, also under bark of fallen 

 trees near ponds, and in stems of Ti/pha latifolia ; local, but not uncommon ; Hythe ; 

 Leicester; Bewdley ; Burton-on-Trent; Bepton, Crevves Pond; Coleshill; Sutton 

 Park, Birmingham ; Hornsea (Yorkshire) ; Scarborough ; Liverpool ; Scotland, very 

 local. Lowlands, Forth district ; Edinburgh ; abundant about Duddingstone Loch. 



(A. quadripunctatus, De G. (sub-gen. Agonum). Smaller than 

 any of the preceding; greenish aeneous, or black with a greenish 

 tinge ; antennfe and palpi black ; thorax double as broad as long, 

 somewhat narrowed behind, with very blunt, somewhat elevated,
