A. tanaceti, L. Of a uniform deep black colour, sometimes 
rather shining, sometimes rather dull, obovate, broad, upper surface almost 
glabrous, under-side sparingly clothed with dusky grey hairs, punc- 
tuation of upper surface very coarse, but coarser and stronger in some 
specimens than in others ; head narrower than thorax, with the frontal 
tubercles moderately distinct ; thorax twice as broad as long, with 
anterior angles projecting and posterior angles slightly obtuse, central 
furrow very broad and shallow ; elytra much widened behind, with 
raised longitudinal lines which in some specimens are much more con- 
spicuous than in others; legs moderate. L. 6-10 mm, 
Male with the fifth ventral segment deeply impressed triangularly at 
apex. 
On Tanacetum vulgare, &e., also in dry sandy and grassy places in various 
localities; local; London district, not uncommon, Darenth, Epping, Caterham, 
Reigate ; Shipley; Hastings ; Eastbourne; Brighton; Portsmouth district ; Bourne- 
mouth ; Bath; Swansea; Barmouth; Snowdon; Norfolk; Bewdley Forest ; 
Knowle; Coleshill; Birmingham; Burnt Wood, Staffordshire ; Louth, Lincolnshire ; 
Northumberland and Durham district ; Scotland, occasional, Solway, Tweed, Argyle, 
and Moray districts ; Ireland, Dublin, Belfast, Antrim, Tyrone, &.; Mr. Blatch 
informs me that he has taken the Jarva on the Devil’s-bit Scabious at Knowle, and 
the perfect insect on wild thyme at Barmouth, &c. ; it is by no means confined to 
the Tansy; I have taken it on the Llanberis side of Snowdon, where I expect its 
food plant was wild thyme. 
A. celandica, Boh. (ville, W. C.; rustica, Steph.). Very like the 
preceding in general shape and appearance, but smaller on the average, 
and less convex, and of a pitchy-brown or fuscous-brown or sometimes 
almost brownish-testaceous colour above with the head black; the 
antenne are shorter, and the frontal tubercles are rather larger, and the 
punctuation of the thorax is shallower and less close, and that of the 
elytra is not so strong; legs and under-side black. L. 6-9 mm. 
Male with the fifth ventral segment deeply impressed triangularly at 
apex. 
On sallows in marshy places; recorded by Stephens as taken in June and 
July on the borders of Whittlesea Mere, and always considered extremely rare; in 
August, 1878, however, Mr. Blatch found it in numbers in Wicken Fen, but, I 
believe, it has not been met with since ; the females often have the abdomen much 
dilated, so that it raises the elytra and projects beyond them as in Gastrophysa. 
SERMYLA, Chapuis. (Age/asa, Motschulsky.) 
This genus, which has by many authors been included under Agelas- 
tica, is distinguished by having the anterior coxal cavities closed behind ; 
the upper surface, at all events of the elytra, is strongly metallic ; the
