Agrilus.| SERRICORNIA. 71 
By beating young birch, hazel, &ec.; local, but not uncommon where it occurs ;

ham, Woking, Tonbridge, &c¢.; Guestling, near Hastings; Southsea; New Forest ; 
Haywood, Glanvilles Wootton ; Hertford; Suffolk; Bewdley Forest ; Trench Woods ;

A. viridis, L. (viridipennis, Lap.; quercinus, Redt.). Rather larger 
than the two preceding species, but closely allied to them in colour and 
general appearance ; it is, however, distinguished by having the eyes 
sinuate on their inner margin, the thorax with tke basal lateral fovez 
less deep, and the elytra not broadly rounded at apex, and the apex 
plainly serrulate, whereas in the other two species the denticulation is 
very indistinct; the last ventral segment of the abdomen, moreover, is 
rounded and has no impression in the male, and the forehead is even 
and not furnished with a shallow furrow on vertex; from A. laticornis 
the species may, of course, be distinguished by the formation of the 
antenne. L. 5-7 mm. 
On young trees, especially oaks; very rare; Buddon Wood.and Mount Sorrel 
(Power) ; Woodford (Turner); York (R. Cooke); Scotland, very rare, Solway 
and Argyle districts; there are very few specimens of the species in our collections, 
and probably large specimens of A. angustulus are often confused with it, 
APHANISTICUS, Latreille. 
This genus contains about forty species, which are widely distributed, 
species having been recorded fiom Egypt and Algeria, Madagascar, 
Natal, Ceylon, Japan, Mexico, the Malay Peninsula, the Australian

Britain, and that very rarely. 
A. pusillus, Ol. (/ineola, Geim.). Elongate, black, shining, with 
a feeble neous reflection, upper surface rather convex ; head large, very 
strongly furrowed, almost bilobed; antenn short, with the first two 
joints thickened, and the last four serrate ; thorax transverse, convex, 
with three transveise impressions, posterior angles acute ; upper surface 
of head and thorax very finely wrinkled, alutaceous ; scutellum small, 
triangular ; elytra at base about as broad as base of thorax, slightly 
widened behind middle, and narrowed towards apex, finely punctured 
in somewhat irregular rows, apex obtusely truncate ; legs black. femora
