Apioil.} RHYNCHOPHORA. 169 



general ; Liverpool district, frequent ; Lancaster and Heysham ; Nortlmmberland 

 and Durham district, apparently rare ; Scotland, Solway, Tweed and Forth districts ; 

 Dr. Power has taken it commonly at Baimuto on Leguminosts : it seems to vary as 

 to its food plant : Walton says that he took it first on Teucrtam in Yorkshire and 

 afterwards on Rumex acetosella on Hampstead Heath, bat that he has never found 

 it in the south on Teucrium. 



A. afifine, Kirby. Very closely allied to the preceding, and not con- 

 sidered distinct by some of the early authors : it is, however, a larger 

 species on the average and may be known by having the temples and 

 throat plainly punctured, and the sides of the thorax evidently more 

 rounded and dilated ; the thorax moreover has the punctuation coarser 

 and deeper and occasionally more or less confluent ; the elytra are some- 

 what wider and more convex ; the colour and the striation of the elytra 

 i.s variable as in the preceding species. L. 2-2^ mm. 



Damp places ; beneath Saroihamnus scoparius and amongst grass and herbage ; 

 the actual food plant, however, is not, apparently, known with any certainty ; local, and, 

 as a rule, not common ; Lee, Caterbam, Horsell (in some numbers, October (Power), 

 Ashtead, Southend, \Veybridge, Bearsted near Maidstone ; Suffolk ; Cam- 

 bridgeshire ; Yorkshire ; Manchester, general (Chappell) ; Lancaster and Heysham ; 

 Northumberland and Durham district; Scotland, Solway and Forth districts; the 

 species does not appear to be found in company with A. marchicum. 



A. violaceum, Kirby (cyanewn, 01.). An elongate species, with 

 the elytra rather depressed on disc, very finely pubescent, somewhat 

 shining ; head and thorax black, often with a slight aeneous reflection, 

 elytra blue or greenish blue ; head a little narrower than thorax, with 

 the vertex punctured, and finely striate between eyes, which are convex 

 and slightly prominent ; rostrum short and stout, scarcely longer than 

 thorax, dull and punctured behind and shining before the insertion of 

 the antennae ; antennae inserted a little behind middle ; thorax a little 

 longer than, or about as long as, broad, with the sides very slightly 

 rounded, strongly, deeply and closely punctured, with a fovea or short 

 broad stria before scutellum ; scntellum rather large, black or bronze, 

 furrowed; elytra long, with sides widened behind, shoulders rounded but 

 marked, punctured striae not deep, interstices flat but somewhat variable, 

 plainly shagreened ; legs dark, more or less metallic, short and stout, 

 tarsi, especially the anterior pair, rather broad. L. 2|-3^ mm. 



Male with the rostrum shorter than in female, and also more strongly 

 pxinctured and more shining at apex ; the pygidium also in this sex is 

 often uncovered. 



On species of Bumex, especially obtusifolius, conglomeratus, erispus and acetosa .- 

 the larva lives in the stalk ; common and generally distributed throughout the king- 

 dom as far north as the Orkney Islands. 



A. hydrolapathi, Kirby (coeruleipenne, Steph.). Closely allied to 

 the preceding with which it is often confounded; the general form, how- 

 ever, is broader and shorter ; the head is considerably broader and more 

 closely punctured ; the rostrum is shorter and thicker at the base ; the 

 thorax is more finely and thickly punctured, and instead of a fovea or
