districts; they run and fly with great swiftness in the sunshine on the 

 open ground or among grass. About four hundred species have been 

 described, of which only four have Ijeen found in Britain. 



Tlie larva of Cicindela hybrida is fully described and figured by Schiodte (De 

 Metamorpbosi Eleutberatorum Observationcs, Part iii., p. 160, Pi. xii. 1). 

 It is pale testaceous with the head and thorax fuscous with a green and purple 

 metallic tinge, and with the ferraora, tibia3, and tarsi fuscous ; the head is large and 

 produced in front of the eyes, and the prothorax is narrow and crescent-shaped with 

 the anterior angles produced ; the abdominal shields are separated except on the ninth 

 segment, and there are no cerci ; on the fifth segment wliich is raised there are two 

 bent hooks, and the anal segment is cylindrical and furnished with short spinose cilia. 



The larva of C. campestris much resembles this, but is more robust. It is figured 

 by Westwood (Classif. i., p. 50), who says that these larva; burrow oylindric 

 retreats in the earth to the depth of a foot or more, employing their legs and jaws in 

 loosening the particles of sand and earth which they carry to the surface on their 

 broad saucer-like head, ascending by the assistance of the two hooks which they bear 

 upon their back. Having completed the burrow, they station themselves by means 

 of their legs and dorsal hooks at its mouth, their large flattened head and first segment 

 fitting the hole. Here they lie in wait for such insects as may be crawling about, 

 and seize and drag them to the bottom of the burrow, to which also they retreat on 

 the first approach of danger. 



Our species may be readily distinguished as follows : — 



I. Labrum and head unicolorous, elytra with larger punctures 



near suture C. stlyatica, L. 



II. Labrum whitish yellow, elytra without larger punctures near 



suture. 

 i. Thorax transverse ; form not cylindrical. 



1. Elytra ^varying from light green to dark green or almost 

 black with five marginal white spots and one white spot 

 just behind centre of disc, the latter surrounded with a 



darker shade C. campesteis, L. 



2. Elytra dark bronze brown with three irregular white 

 bands, the middle one simply waved, forehead gibbous 



in front C. HYBRIDA, Z. 



3. Elytra dark bronze brown with three irregular white 

 bauds, the middle one bent downward from centre to- 

 wards apex of elytra; forehead not gibbous in front ... V. marilima, Dpj. 



ii. Thorax elongate; form cylindrical C. GERMANICA, L. 



C. sylvatica, L. Bronze-brown with a purplisli tinge ; laltruni 

 large, concolorous with head, with a distinct tooth in the middle of 

 anterior margin, and with a strong longitudinal keel on disc ; thorax 

 rather finely rugose ; elytra long oval, longer in proportion than in 

 the succeeding species, variolose, thickly punctured, with a spot at 

 shoulder, another oblique marking before middle, a round spot 

 before apex, and an irregular band just behind niidiUc, Avhite or very 

 liglit testaceous ; none of these except the humeral spot touch the 

 margin ; underside of legs and body clothed with white hairs, the 

 former metallic. L. 14-lG mm. 



Local, but common where it occurs; sandy heaths; Claygatc, Woking, Chobham, 

 Weybridge; Bournemouth; also near Cambridge. 



C. campestris, L. Colour varying from bright grass green to 

 ixlmost black ; base of antenna', anterior and posterior margins of tho-
