76 ADEPHAGA. [Awara. 



This species ver}'' closely resembles A. ovafa, but besides the fact that 

 the intermediate tibife of male are entirely glabrous, it is rather broader 

 and larger, as a rule, than that species, and has the apex of the elytra 

 more acuminate, the stria3 deeper, and the interstices more convex. 



A. nitida, Sturm. Ovate, upper side bronze or metallic green, 

 very smooth and shining ; antennae black with the three first joints and 

 base of fourth red ; thorax broader than long, slightly broader at Ijase 

 than base of elytra, narrowed towards the front, anterior angles rounded, 

 not projecting, base impunctate, basal impressions absent or very faintly 

 traceable ; the usual pore at the posterior angles is placed close to 

 the base and at some little distance from the sides ; elytra w^ith the striae 

 plainly stronger towards apex, interstices smooth ; femora black, tibiae 

 reddish, tarsi brownish red. L. 7^ mm. 



This species has been lately introduced into the British fauna on the 

 authority of a specimen taken by Mr. Gillo near Bath, and named as 

 above by M. Bedel ; I have recently received two old specimens of an 

 Arnara from Warwickshire which appear to belong to this species; they 

 were sent me by Mr. E. Clark, 



This species differs from A. communis pa\A A. hmicoUis by the sculpture 

 of the thorax and the rounded anterior angles of the same ; its form 

 also is shorter and more oval, 



A. tibialis, Payk. The smallest species of the group, oval, convex, 

 shining brassy, or brassy black, sometimes with greenish reflection ; an- 

 tennae dark with first three joints (sometimes two) red ; thorax transverse, 

 slightly contracted in front, broadest at base, posterior angles right 

 angles, dorsal furrow deepest in middle, base with two distinct and 

 deeply impressed fovese ; elytra finely striated, the striae plainly 

 punctured, scutellary stria absent ; legs black, tibiae lighter, L, 4 mm. 



Easily distinguished from all the allied species by its small size, the 

 deeply impressed foveae at base of thorax, and the absence of the 

 scutellary stria on the elytra, which is at most occasionally indicated by 

 a few punctures. 



Widely distributed and locally abundant in England; Scotland, local, Lowlands; 

 Ireland, near Belfast, not common near Dublin, probably widely distributed. 



A. lunicollis, Schiodte (vulgaris, Panz,, nee Dawson, G. D.). Of the 



size of one of the largest examples of A. commuiiis, which species it 

 strongly resembles, but distmguished by having at most two joints of the 

 antennae red, and the fact tliat the base of the thorax is almost entirely 

 impunctate, and also by the colour of the legs, which are usually en- 

 tirely black, whereas in communis the tibiae are distinctly lighter ; the 

 thorax is longer in proportion than in some of the allied species, with 

 central furrow and basal foveae often very indistinct, posterior angles 

 somewhat obtuse ; elytra plainly but ratlier finely striated, the striae 

 somewhat deeper behind, and occasionally obsoletely pimctured in front. 

 L. 7-7k nim.
