Two species are recorded in the Munich catalogue as belonging to 
this genus, one from Europe and the other from Japan, and three more 
have since been added by Mr. Baly from Australia, Moreton Bay, and 
Sanju; the species is usually joined in our catalogues with Sermyla 
(Agelasa) halensis, but the fact that the latter genus has the anterior 
coxal cavities closed behind, whereas in Agelastica they are open, will 
at once separate them; the single European species is extremely rare 
in britain, and has not, as far as I know, been met with for many 
years; it is the Adimonia alni of Stephens, and is figured by him in 
the Illustrations, Mandibulata, vol. iv. p. xx. fig. 5. 
A. alni, L. Oval, rather convex, shining, of a deep violet or bluish- 
violet colour, with the antennae, tibie and tarsi black, the former with 
the first two joints metallic ; head narrower than thorax, with a central 
furrow, antennz rather stout, with the third joint plainly longer than 
the second, but shorter than the fourth; thorax somewhat convex, 
broadest behind middle, somewhat narrowed in front. disc thickly 
punctured, often impressed on each side at or before middle ; scutellum 
smooth, triangular; elytra about as thickly punctured as thorax, but 
with the punctuation stronger ; legs moderately long. L. 6-7 mm. 
Male with the fifth ventral segment of the abdomen slightly impressed 
in a semicircle at apex. 
On alders; very rare; Stephens records it from near London, Exeter and Bristol, 
and says, ‘‘ I have formerly obtained several specimens from near Exeter, where they 
were captured in June; ” there is no reason why it should be so rare in Britain, as it 
is far from uncommon on the Continent.
