Sp. 3. cupreus. Elongatus, subtiis nigro-wneus, supra rufo-purpureo- aut viridi- 

 cupreus, elytrorum basi scepejlavd, his tenue striatis, thorace profunda canali- 

 culato. ' (Long. corp. 5— 7| lin.)

 No. 1266. — Var. El. chalybeus. Sowerby, i. pi. 72. 



Beneath black-brass or cupreous, above various tints of red-purple or green- 

 copper, or dusky ; thorax elongate, thickly and rather coarsely punctate, with 

 the posterior angles elongate, carinate : elytra rather faintly striate, the in- 

 terstices obscurely punctured, the base more or less yellow or ochreous, but 

 frequently concolorous with the apex: antennas and legs black, the latter 

 slightly asneous. 



Scarcely two examples of this protean species occur precisely alike in the colour 

 of the upper surface, which in different individuals partakes of nearly every 

 colour of the rainbow; a great proportion have the base of the elytra fla- 

 vescent, in some instances the colour occupying two-thirds of the surface, 

 while in others it gradually vanishes, till at length the entire disc is con- 

 colorous with the apex ; every possible shade and proportion occurs, so that 

 it becomes impossible to discriminate the varieties. 



Inhabits similar places with the former ; females generally rare ; 

 at least fifty males to one female having usually occurred ; but in 

 August, 1829, out of scores of specimens now under my inspection, 

 captured by the Rev. F. W. Hope and C. Darwin, Esq., in North 

 Wales, scarcely a single male was observed. " Holme-Hill. ,, —

^Sp. 4. castaneus. Niger, thorace pube fulvescente mutabili tecto, elytris Jlavis 



apice summo nigris. (Long. corp. 5 lin.) 

 El. castaneus. Linne. — CI. castaneus. Steph. Catal. 125. No. 1267. 



Body beneath, head, antenna?, and legs black : thorax also black, thickly clothed 

 with a short fulvescent down : scutellum black: elytra testaceous-yellow, with 

 the apex black, the disc striated, the interstices punctured. 



I believe that hitherto a single elytron only of this insect has 

 been found in Britain, and that was picked up by the late W. 

 Hooker, Esq. on Moushold-heath, near Norwich. 



B. With the antennas serrated in the males, simple in the females. 

 Sp. 5. sanguinicollis. Niger puhescens, thorace toto sanguineo. (Long. corp. 

 4 lin.)
