B. Legs dark, except tibiae, which are lighter. 



a. Striae on elytra feeble, not deeper belaud . . A. TEIVIALIS, Gi/ll. 



b. Stri.-E on elytra stroug-, deeper behind. 



a*. Series of pores on 9th interstice of elytra 

 widely interrupted in middle ; elytra nar- 

 rower, less oval A, COMiitTNis, Panz. 



h*. Series of pores on 9th interstice of elytra 

 regular from base to apex ; elytra wider, 

 more oval A. CONTINUA, Thorns. 



A. ovata, F. (obsolefa, Dej.), Ovate, broad, brassy, occasionally 

 greenish or bluish, sometimes almost black ; antennae with the threo 

 first joints and base of the fourth red ; thorax transverse, narrowed in 

 front, anterior angles prominent, broadest at base, posterior angles 

 somewhat obtuse, dorsal furrow fine, base impunctate, with two more 

 or less obsolete farrows on each side, the outer one often imperceptible, 

 the inner one often resolving itself into a small deep depression re- 

 moved to some distance from basal margin ; elytra broad, plainly 

 striated, the striae becoming deeper at apex, not punctured ; legs quite 

 black, L. 9-11 mm. 



Widely distributed throughout England from north to south, but it cannot be 

 called common. Scotland, not common, maritime, Tweed, Forth, Sol way, Clyde; it 

 is, however, by no means a maritime species exclusively. I can hud no record from 

 Ireland. 



A. similata, Gyll. {ohsoleta, Duft.). Smaller, as a rule, and nar- 

 rower than the preceding, and usually more brassy ; the thorax is not 

 so broad at the sides, nor so much widened at base, and the basal im- 

 pressions are less obsolete and more or less punctured ; striae of elytra 

 presenting traces of feeble punctuation ; tibiae reddish. L. 9-10 mm. 



In distinguishing this from the preceding species too much stress must 

 not always be laid upon the light tibiae, as somewhat immature speci- 

 mens of ovata have the legs lighter : the broad form and impunctate 

 base of thorax are more relialjle characters for that species. 



Widely distributed and usually common throughout England, especially in the 

 south ; apparently not recorded from Scotland ; Ireland, common near Dublin. 



A. acuminata, Payk. {eunjnota, Dej., vu/f/ans, F.). Ovate, very 

 l)ioad, shining Ijrassy, sometimes greenish or blackish; antennae with 

 the three first joints and base of the fourth red ; thorax narrowest in 

 front, broadest at base, posterior angles rather sharp, but not produced 

 laterally, dorsal furrow abbreviated in front and behind, base with a short 

 and deep fovea at some distance from hind margin, and a shallow im- 

 pression, sometimes obsolete, ne;u' the angles ; elytra more acuminate 

 at apex than in the other species, finely but sharply striated, the striie 

 imiMinctate, third, fifth, and seventh interstices often slightly raised ; Irgs 

 entirely black. L. 9-11 mm. 



Widely distributed, but local ; not common in the London district; Favcrsham, 

 Chatham, Mickleham, &c. ; Margate; Hepton ; IJridliiiglon ; Northun)l)orland and 

 Durham; Scotland, cf)mni()ii Lowlands, also occura iu the Moray diolrictj Ireland, 

 near Belfast, and not unoommou near Dublin.
