tremities, the wings are long, the palpi slightly truncated, and tlie 

 penultimate joint of the tarsi is very strongly bifid. All the species 

 frequent broom, and are of lively, brilliant, colours.

The head is bluish-green, strongly punctate : the thorax is ferruginous-red, 

 rather convex, strongly punctate, with a distinct longitudinal impressed line 

 in the middle, and a transverse line, which divides the lobated appendage : 

 the scutellum is dusky : the elytra are rather broader than the thorax, their 

 angles are rounded, and their colour varies from clear green to blue and dusky ; 

 they are highly glossed and brilliant, and have impressed subpunctate striae, 

 the spaces between which are more or less punctate : the breast and the ab- 

 domen are bluish-green : the legs are ferruginous, with the tips of the thighs 

 and the tarsi dusky or blackish : the basal joint of the antennae is rusty-red : 

 the remaining joints and the palpi are dusky-brown. 

 This species varies considerably in the colour of its elytra, and also in size : some 

 specimens, as above noticed, are fine green, others deep blue ; and it is ob- 

 served by M. De Jean that the larger specimens on the continent are usually 

 of the former colour. I may here remark as a general rule, that aU insects that 

 are usually of a green colour, vary to different shades of blue, and vice versa. 

 Not a very common insect ; I have seen about twenty specimens 

 only, most of which were captured at Darentli in Kent, six by my- 

 self out of the common broom : it has also been taken at Windsor, 

 and at Netley in Shropshire ; and in June last I found a specimen 

 at Ripley in Surry.

The principal differences between this insect and La. cyanocephalus arise 

 from the present species having the base of the antennse, the tibite, and the 

 tarsi dusky, the two former of which are rufous in cyanocephalus : the head 

 is blue-green or dusky : the thorax rufous : the elytra deep blue or greenish ; 

 striated, with impressed dots between the striae, and two more deeply impressed 

 spots between the second and third strise from the suture : the antennse are 

 dusky, with a rufous tinge on the under side of the basal joint: the abdomen 

 is blue-black, the breast red; the base of the thighs red, their tips blue- 

 black ; their shanks dusky, with a paler hue on their under-side ; the tarsi 

 dusky.
