AnthicUS.] HETEEOMERA. 87 



much so as in the two first species, rather distinctly punctured, with a 

 smooth line in middle behind ; antennae moderately long and slender, 

 red ; thorax in front at least as broad as head, much narrowed behind, 

 distinctly and not very closely punctured ; elytra oval, broadest about 

 middle, comparatively strongly punctured, with the shoulders almost 

 rounded; femora dark, tibiae and tarsi reddish-testaceous. L. 3-3 j mm. 

 Male with the posterior tibiae very strongly and spathulately dilated 

 externally at apex. 



Salt marshes ; in refuse, &c. ; often beneath decaying seaweed ; locally common ; 

 Gravesend, Southend, Sheerness, Whitstable; Margate; Hastings; Sundown; 

 Southampton ; Wivenhoe. 



A. ang-ustatus, Curt. Pitchy or dark brown, with yellowish 

 pubescence which is very distinct and rather coarse ; head comparatively 

 long, rounded at basje, somewhat produced before eyes, rather strongly 

 punctured, with a smooth, more or less interrupted, central line ; an- 

 tennae moderately long, red ; base of head and thorax often red or 

 reddish, disc of latter dark ; the colour, however, is variable ; thorax 

 obovate, about as wide in front as head, and thence gradually and 

 slightly narrowed behind, distinctly punctured ; elytra subparallel, closely 

 and rather strongly punctured ; legs red, femora scarcely darker ; the 

 entirely red legs and the obovate shape of the thorax will distinguish 

 this species from all our others except A. scoticus, from which it may 

 be known by the narrower and more parallel form and evidently longer 

 thorax ; it is very distinct and easily separated from our other members 

 of the genus, but I am not at all sure that it is not synonymous with 

 one of the many allied European species. L. 2-2 f mm. 



Salt marshes, and on the "beach under seaweed ; rare ; Gravesend ; Southend ; 

 Wrabness (Essex) ; Hastings; Portsmouth district ; Ventuor, Isle of Wight (rare on 

 the beach) ; Portland ; Bristol. 



A. scoticus, Rye. Leaden black, dull, thickly clothed with rather 

 shining greyish pubescence, antennae and legs lurid-testaceous or almost 

 entirely pitchy ; head broad, with the base truncate, strongly and 

 closely and somewhat rugosely punctured, with an impunctate central 

 line; thorax short and broad, almost transverse and subglobose, closely 

 punctured, but not so strongly as head ; elytra much broader than 

 thorax, truncate at base, comparatively short and broad, with close, rather 

 strong, and in some place s almost confluent punctuation; the species is 

 closely allied to A. angnstatus, but may be easily known by its broader 

 and stouter build, the shorter thorax, and the generally darker colour 

 of the upper surface, legs and antennae ; the colour appears to be vari- 

 able, as my single specimen has the legs and antennae entirely red, and 

 the base of the elytra towards shoulders with a tendency to become 

 obscurely reddish. L. 2|-3 mm. 



Very local ; Scotland, Forth, Clyde, and Dee districts ; Paisley (Morris Young);
