general; Liverpool district, frequent; Lancaster and Heysham ; Northumberland 
and Durham district, apparently rare ; Scotland, Solway, Tweed and Forth districts ; 
Dr. Power has taken it commonly at Balmuto on Leguminos@; it seems to vary as 
to its food plant: Walton says that he took it first on Teuwcriwm in Yorkshire and 
afterwards on Aumex acetosella on Hampstead Heath, but that he has never found 
it in the south on Tewerium. 
A. affine, 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 
is variable as in the preceding species. L. 2-25 mm. 
Damp places; beneath Sarothamnus 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, Caterham, Horsell (in some numbers, October (Power), 
Ashtead, Southend, Weybridge, 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 4, marchicum. 
A. violaceum, Kirby (cyaneum, Ol.). An elongate species, with 
the elytra rather depressed on disc, very finely pubescent, somewhat 
shining ; head and thorax black, often with a slight neous 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 antenne ; antenne 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 ; scutellum rather large, black or bronze, 
furrowed; elytra long, with sides widened behind, shoulders rounded but 
marked, punctured striz 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. 23-3} mm. 
Male with the rostrum shorter than in female, and also more strongly 
punctured and more shining at apex ; the pygidium also in this sex is 
often uncovered. 
On species of Rumez, especially obtusifolius, conglomeratus, erispus and acetosa ; 
the larva lives in the stalk ; common and geuerally distributed throughout the king- 
dom as far north as the Orkney Islands. 
A. hydrolapathi, Kirby (cerulezpenne, 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
