EEV. T. A. MARSHALL — CORTlS'ODINORUM EECENSIO. 45 



Vertex with a liueai- impression, thickly punetulate ; face between the 

 eyes bright metalhc green. Thorax finely punetulate, the punctures 

 much smaller than those of the elytra. Elytra moderately punctured, 

 more coarsely towards the shoulders and sides ; the punctures only 

 partially arranged in strise. Lateral tubercles of the elytra arranged 

 in three interrupted costate lines commencing at the humerus ; the 

 inner series double at the base, obsolete before the middle of the 

 elytron ; the second series extending in a costa beyond the middle ; 

 both these series are interrupted by a broad transverse impression, 

 abbreviated on both sides : third series not interrupted by the trans- 

 verse impression, prolonged in a smooth costa to the apex. Under- 

 side and legs with fulvous pubescence. 

 Var. With the thorax dark blue, underside and legs dull purple ; the 



lateral costfc and tubercles much less developed. 

 The elongate anteim^e of the J and (in tlie specimen examined) 

 the different colour of tlie upper surface, witli tlie absence of 

 tubercles, caused me at first to regard it as a different species. 

 I am ignorant whether examples of the female occur of a bright 

 copper colour. The following is a description of the male in the 

 Eev. H. Clark's collection: — 



C. oblongo-ovatus, convexus, confertim subtiliter punctulatus, vertice 



sulcato ; supra la^te purpureo-cupreus ; oculorum orbitis, scutello, 



thoracis elytrorum marginibus, siitura tenuiter, viridi-cseruleis ; cor- 



pore subtus et pedibus cyaneis, fulvo-hirtis ; antennis tarsis nigris. <? . 



Long. 3^ lin. ; lat. hum. If lin. 



Regularly oblong-ovate, moderately convex, finely and densely punc- 

 tured — the vertex especially, where the punctures are oblong and 

 confused. Labrura and vertex of a bright purplish copper-colour, 

 the latter furrowed longitudinally ; the orbital region blue ; mandi- 

 bles and antennjE black. Thorax seen from above sem.ielliptical, trun- 

 cate at the base, and rounded in front, where it is only one-third as 

 broad as at the base ; its anterior angles less than right angles, not 

 produced ; faintly sinuated on each side behind the eyes ; purplish 

 copper, very brilliant, finely and densely punctured, margined with 

 bluish green at the sides and base. Scuteilum semiorbicular, pohshed, 

 bluish green, with a few punctules. Elytra concolorous with the 

 thorax, more coarsely punctured, the punctures arranged in indis- 

 tinct stride continued to the apex ; the suture narrowly bluish green. 

 Beneath, with the legs, cyaneous ; hairs of the tibiae and pulvilli pale 

 fulvous. 

 Hub. Sarawak, Borneo ; discovered by Mr. Wallace. 

 In the collections of the Eev. H. Clark, Mr. Baly, and the 

 British Museum.
