occurred OD the whitethorn only in the New Forest; the specimens differ con- 

 siderably in size ; in continental examples the female often has the thorax of n 

 purplish colonr, and the elytra Bonn-times cyaneous. Stephens (I Hunt, iii. 238)

 have been some error in his record, as it has long been erased from our lists.

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 thu 

 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 

 llritain; they are obtained by beating young birches, oaks, hazel, thorn 

 bushes, <fec. 



The larva of A. biffttttatiu, which is found under the bark of oak, is described by 

 SchiSdte (Part iv. p. 374), but does not appear to present any striking characteris- 

 tics ; that of A. viridis has been described by Aube, 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 

 larvae change to pnpse at the beginning of May, and the perfect insect appears about 

 the middle of June ; the pupae, as is the ca>e with all the Bupreotidie, have neither 

 " ityli 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 before apex .... A. BIGTJTTATU3, F . 

 ii. Sculpture of elytra closer ; elytra coppery or 

 purplish-red, with white spots before apex almost 



always absent A. SINCATU3, 01. 



II. Size smaller; tarsal claws toothed at base. 



i. Colour nnicolorous olive-green, rarely greenish- 

 bronze, very rarely bluish. 



1. Antenna? strongly dilated in mala A. LATICORNIS, III. 



2. Antennae simple, not dilated in male. 



A. Last segment of abdomen emarginate, longi- 

 tudinally impressed in male ; average size 



smaller A. ANOUSTULUS, ///. 



B. Last segment of abdomen rounded, not im- 

 pressed in male ; average size larger .... A. VIBIDIB, L. 



A. blgruttatu,F.,n^c Rossi (pannonicus, Filler; Anamlus bignftatus, 

 Thorns.). Of a brilliant blue or bronze-green colour, occasionally aeneous; 

 head rugosely punctured, with the forehead impressed, antennae short, 

 of a dark metallic colour; thoiax transverse, very slightly rounded at 

 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 

 binnll spot of white hairs on each near suture before apex; under-side
