are much narrower ; tlie "basal foveas are also considerably smaller. L. 

 7 mm. 



Marshy places, river banks, &c. ; widely distributed, but rather local ; commoner 

 in the southern and midland districts of Enghmd than in the north ; Scotland, Low- 

 lands, very local near the mouths of titlal rivers, Sohvay district ; abundant on the 

 banks of the Nith below Dumfries ; I can find no record from Ireland. 



A. viduus, Panz. Black, with a distinct greenish or brownish 

 bronze reflection, especially on the elytra ; antennae and palpi black ; 

 thorax broader than long with sides evenly rounded, margins reflexed 

 especially at posterior angles which are more plainly rounded than in 

 the preceding species, dorsal furrow distinct, basal angles with a large 

 somewhat deeply impressed slightly rugose fovea ; elytra more parallel- 

 sided in the male than in the female, deeply striated, the striie feebly 

 punctured, interstices convex, the third with three pores ; legs black. 

 L. 8-9 mm. 



Marshy places, at roots of grass and trees, not uncommon ; Lf^e, Darenth Wood, 

 Wimbledon, Weybridge ; Reigate; Deal; Bournemouth; Reptou and Burtou-on- 

 Trent ; Gumley, Market Harborough ; Bewdley ; Colchester ; Liverpool ; Yorkshire ; 

 Newcastle-on-Tyne. Scotland not common, Clyde and Moray districts. Ireland, 

 near Belfast (perhaps the v. moestus). 



V. moestus, Duft. Smaller than the type, Avith rather narrower 

 thorax, and perfectly black without any metallic reflection ; it has been 

 regarded as a separate species, but there is no real structural difference. 

 Commoner than the type form, but very often taken in company with 

 it : it is not common in Scotland, but, unlike the type, occurs in the 

 Forth and Solway, as well as the Clyde districts, and is not found in the 

 Moray district. 



A. versutus, Gyll. Very like A. vidmis, but smaller, and easily 

 distinguished by the much finer strise and flat interstices of tlie elytra, 

 and also by its considerably shorter and more transverse thorax, which is 

 fully as broad behind as in front, whereas in A. viduus it is distinctly 

 narrower behind ; it is also a more shining insect ; the first and second 

 joints of the posterior tarsi are shining and simply convex, Avhereas in 

 A. viduus they are dull and are furnished with a strong keel on their 

 upper side. L. 7-7^ mm.
