Sp. 6. ustus? Subconvexus, virescente-ceneus, antennis palpis pedi 



lidis, elytris striatis, apice lasvibus pallidisque ; subtus ferrugineus, aut ceneo-

Ca. ustus. Schotiherf—Pe. ustus. Steph. Catal p. 38. No. 365. 



Greenish-brass or dusky-green, rather shining ; a little convex : head subviolet, 

 with the usual frontal impressions : antennae and palpi pale ferruginous : 

 thorax smooth, subvirescent, with a dorsal line and two large punctate basal 

 impressions, one on either side : elytra rather convex, glossy, crenato-striated, 

 the striae obliterated before the apex, and towards the margin ; the apex pale 

 ferruginous-brown, very smooth : beneath ferruginous or brassy-black : legs 

 pale rufo-ferruginous. 



Taken in Norfolk, and in Yorkshire ; but, I believe, somewhat 

 rarely. 



Sp. 7. decorus. Subdepressus, virescens, antennarum basi pedibusque ferru- 

 gineis, elytris striatis, apice sublcsvibus pallidisque, subtus niger. (Long, 

 corp. 2^ — 3 lin.) 



Be. decorus. — Panzer? — Pe. decorus. Steph. Catal. p. 38. No. 366. 



Similar to the last, but more depressed and smaller ; the colour different, &c. 

 Above bright greenish : head with the two usual impressions, rather deep : 

 thorax rather glossy, with a faint dorsal line, and a shallow impressed line on 

 each side at the base : elytra bright greenish, with the tip pale pitchy-ferru- 

 ginous; crenato-striated, the striae becoming obliterated at the sides and 

 towards the tip, the sutural one carried on to the apex itself: body beneath 

 brassy-black: legs ferruginous: basal joint of the antennae the same; the 

 rest, and the terminal joints of the palpi, dusky. 



Not a very common insect ; found occasionally in damp gravel- 

 pits, &c. near London. " Sandy-lane, at Richmond." — Rev. T. T. 



Haverfield. 



B. With the elytra immaculate. 



Sp. 8. nitidulus. Subdepressus, nigro-coerulescens, aut virescens, nitidus, anten- 

 narum basi tibiis tarsisque rufescentibus, elytris punctato-striatis, apice sub" 

 IcEvibus. (Long. corp. 2—2^ lin.) 



Ca. nitidulus. Marsham.—Ve. nitidulus. Steph. Catal. p. 38. No. 368. 



Glossy deep-blue or greenish : head and thorax dusky-blue ; the former with 

 two slight frontal impressions, the latter with a faint dorsal channel, and the 

 hinder margin punctate, with an impression on each side near the angles : 

 elytra immaculate shining greenish, or blue, punctate-striated, the striae not 

 reaching to the apex, and the lateral ones somewhat obsolete: legs dusky 

 black or pitchy, with the tip of the thighs, tibiae, and tarsi rufescent: 

 antennae with the base rufescent, the apex dusky : palpi with the terminal 

 joints dusky. 



Rather a local species ; occurring, however, in tolerable plenty in 

 the gravel-pits on Wimbledon-common, and occasionally in those
