MELYRIDiE. MALACH1US. 313 



Somewhat rare : I have taken it at Darenth-wood, and it has 

 occurred in other parts near London. " Cobham, Surrey, July." 

 — Dr. Leach. " Baron- wood."' — T. C. Hey sham, Esq. " Near 

 Cambridge." — J. C. Dale, Esq. " Mr. Jeffreys has noticed it 

 very abundant on the flowers of Arundo arenaria in June." — L. W. 

 Dillwyn, Esq.

Curtis, iv. pi. 167. $. 



Green or bluish, pubescent: head flavescent in front: thorax with its lateral 

 margins pale sanguineous : elytra with an ovate pale sanguineous spot at the 

 apex within : legs and antennae dull green, the latter with several of the basal 

 joints dilated in the male, which sex has an acuminated tubercular process on 

 the spot at the inner apex of the elytra, concolorous therewith. 



No doubt can exist of the insect last referred to being the male of M. marginellus, 

 Messrs. Chant and Bentley having taken several pairs in copuM, while in 

 Devonshire ; and who remarked that their voracity was so inordinate, that if 

 a pair were confined in a box for a single night, one only remained alive in 

 the morning, the fragments of its partner being strewed about. 



Found chiefly on the coasts, and on those of Norfolk, Suffolk, 

 Essex, Kent, and Devonshire, it has occurred. " Southend." — 

 Re®. F. W. Hope. " Borders of Slapton Ley, Devon." — Messrs. 

 Chant and Bentley. 



Sp. 5. bituberculatus. Nigro-ceneus, glaber, elytrisfuscis, fascid viedifi abbre- 

 viat/2 apiceque Jlavis, in ipso apice tuberculis duabus atris. (Long. corp. 

 li— If lin.) 



Ma. bituberculatus. Steph. Catal. 135. No. 1382. 



Black-brass, glabrous ; mouth flavescent: thorax immaculate: elytra fuscous, 

 or black, with a transverse fascia a little before the middle, not reaching to the 

 suture, and the apex yellow or rufescent, the latter with two black tubercular 

 processes. 



The tubercular processes at the apex of the elytra distinguish this insect from 

 the following: I possess the sexes of each ; the above is therefore not a sexual 

 distinction. 



Not very common : found in the vicinity of London, at Hert- 

 ford, Daren th, Coombe, &c, in hedges. 



Sp. 6. fasciatus. Nigro-asneus, glaber, elytris nigris, fascia media abbreviate, 

 apiceque simplice rufis. (Long. corp. 1^ — if lin.)
