angled in the middle of sides, and has a deep depression on each side of 
disc, and the elytra are thickly set with deep subocellate punctures.

excised triangularly at apex.

The G. calmariensis of Fabricius is the G. zanthomelena of Schrank 
and the European catalogue. 
G. tenella, L. Considerably smaller, on an average, than ordinary 
specimens of the preceding, which it much resembles ; it may, however, 
be easily distinguished by its rather broader form and less pubescent 
thorax, as well as by the lighter colour of the antenne, of which the 
third joint is longer in proportion to the second ; the tubercles on the 
forehead are more distinct and shining, the central channel of the thorax 
is more marked, and the subocellate punctures of the elytra are less 
deep ; the sexual characters are also different, the male having the fifth 
ventral segment of the abdomen slightly impressed at apex, the same 
segment being almost entire in the female; the central line of the 
thorax and the humeral callosities are usually infuscate, and occasionally 
the elytra are marked with a more or less obsolete dark band. L. 
22-35 mm. 
In marshy places; on willows, especially in osier beds, and also on alders and 
Spirea ulmaria ; locally common ; London, Southern, and Midland districts, widely 
distributed ; Yorkshire; Cheshire ; Northumberland and Durham; Cumberland ; 
Scotland, Solway, Tweed, and Forth districts ; Ireland, Armagh. 
ADIMONIA, Laicharting. (Galeruca, Geoffroy.) 
This genus, as here constituted, contains about seventy-five species, 
which are chiefly found in Europe and Northern and Central Asia; 
a few, however, have been described from North America, Morocco 
and Algeria, and Southern Africa, and one from the Australian region ; 
no less than forty-four are found in Europe, of which two only occur 
in Britain ; they are larger than any of our other Galeruce, and may be 
known by having the anterior coxal cavities closed behind, and the 
intermediate tibia armed with a small spur at apex ; the upper surface 
is very finely pubescent, almost glabrous; the tarsi are rather wide, 
and have the third joint the broadest, and the tarsal claws are strong 
and armed with a tooth. 
I, Colour entirely black ; antenne longer, with the third joint 
longer in proportion to the second ; thorax more deeply and 
closely punctured; size larger . . . . . . + « + + A. TANACETI, L,
