El. sanguinicollis. Hellwig. — CI. sanguinicollis. Steph. Catal. 125. No. 1268. 

 El. ruficollis. Don. xv. pi. 618. f. 1. 



Black : head and thorax very pubescent ; the latter attenuated in front, slightly 

 depressed, and entirely of an immaculate blood-red; elytra bluish-black, 

 rather faintly striated, the interstices punctured, somewhat pubescent, the 

 margin ciliated ; legs black ; tip of the last joint of the tarsi rufous : antenna? 

 serrated, black. 



Very rare : occasional captures of the insect have been made 

 within the metropolitan district; it also occurs in Norfolk. " Hyde- 

 park, by Mr. B. Clark ; and Windsor, by W. Griesbach, Esq." — 

 Dr. Leach. " Copenhagen-fields." — Mr. Bainbridge. 



Sp. 6. tessellatus. Cupreo-ceneus pubescens, thorace elytrisque maculis grisco- 



villosis tessellatis, unguihus rufis. (Long. corp. 5 — 7^ lin.) 

 El. tessellatus. Linne— €1. tessellatus. Steph. Catal. 125. No. 1269. 



Dusky or coppery- brass, pubescent : thorax and elytra clothed with short de- 

 pressed cinereous hairs disposed in tessellated patches, most distinct on the 

 elytra, but of variable form, sometimes being equally distributed over the sur- 

 face, and at others occupying the alternate interstices only between the stria? 

 on the elytra: legs concolorous with the body, with the claws rufous: an- 

 tennae black. 



Found in marshy pastures and meadows, but local near the me- 

 tropolis; the only locality that I am aware of being in a field near 

 the " Red House," Battersea-fields, where it is sometimes found in 

 plenty; it occurs in Norfolk. " Epping." — Mr. Doubleday. " Com- 

 mon in Bottisham and Horningsea Fens. 1 ' 1 — Rev. L. Jenyns. " In 

 moist meadows, common, particularly about Penllergare and Sketty, 

 and Mr. Jeffreys has found it under rubbish, near high- water mark."

Sp. 7. metallicus. Oblongus, fusco-ameus, pubescens, thorace convexo lasvi, an- 



tennarum basi pedibuscjue testaceis. (Long. corp. 4 — 5 lin.) 

 El. metallicus. Paykul— CI. metallicus. Steph. Catal. 125. No. 1270. 



Oblong, brassy-fuscous, pubescent : forehead rugose-punctate : thorax convex, 

 the sides rounded, with elongate, acuminate, posterior angles : the disc de- 

 licately punctured : elytra a little attenuated towards the apex, which is acu- 

 minated ; the disc faintly punctate-striate, and rather glossy : body beneath 

 brassy-black, shining: legs pale testaceous; tarsi fuscous: antenna? with the 

 basal joint ferruginous, the rest black. 



This species ill associates with the rest of the genus; amongst other characters 

 it has the basal joint of the antenme large and bent, and the sides of the thorax 

 dilated : in form it closely resembles the insects of the following genus, but 

 its surface is pubescent, and not glabrous, as in them.
