Anthaxia. | SERRICORNIA, 69 
occurred on the whitethorn only in the New Forest; the specimens differ con- 
siderably in size; in continental examples the female often has the thorax of a 
purplish colour, and the elytra sometimes cyaneous. Stephens (Illust. iii. 238) 
records Anthaxia salicis from Lordship Lane, Dulwich, but there evidently must 
have been some error in his record, as it has long been erased from our lists. 
AGRILUS, Solier. 
This genus is a very large and extensive one, and, as far as is at 
present known, contains nearly five hundred species, which are very 
widely distributed over the surface of the globe, from Siberia in the 
north to Patagonia in the south; the majority, however, occur in tropical 
countries; about fifty are found in Europe, of which five only occur in 
Britain; they are obtained by beating young birches, oaks, hazel, thorn 
bushes, &e. 
The larva of A. biguttatus, which is found under the bark of oak, is described by 
Schiédte (Part iv. p. 374), but does not appear to present any striking characteris- 
tics; that of A. viridis has been described by Aubé, who detected it in the stems 
of young beech trees, which were much injured by its attacks ; according to West- 
wood (Classif. i. p. 230) the larva is apod, broadest in front, and gradually diminishes 
towards the extremity of the body, which is armed with two horny points. These 
Jarvee change to pup at the beginning of May, and the perfect insect appears about 
the middle of June ; the pup, as is the case with all the Buprestide, have neither 
‘* styli motorii ’’ nor cerci. 
The five British species may be divided as follows :— 
T. Size larger; tarsal claws split at apex. 
i. Sculpture of elytra less close ; elytra blue or greenish, 
with two distinct white spots beforeapex . . . . A. BIGUTTATUS, F. 
ii. Sculpture of elytra closer; elytra coppery or 
purplish-red, with white spots before apex almost 
always absent.) igi a sie) 2) tees © Woy ie AS SINDATUS, O],

sides, uneven, transversely rugose; scutellum with a strong transverse 
engraved line; elytra depressed on disc, slightly broader at base than 
thorax, rather strongly acuminate towards apex, with shoulders plainly 
marked, rather closely and rugosely sculptured, with a very distinct 
small spot of white hairs on each near suture before apex; under-side
