of the Family Buprestidaj. 263 



General form of A. viridicenea, De Geer, but much less 

 convex. Clypeus very deeply eraarginate. Thorax with the 

 central channel not very deep, elliptical, closely punctured. 

 The surface on each side finely punctured ; the sides densely 

 and coarsely punctured, but the punctures are smaller and 

 much closer than in viridianea. The basal fovea on each 

 side of the base is deep and sharply defined. The suture is 

 rather flat, smooth, except a few fine punctures at the apex. 

 First interstice flat, with an irregular line of fine punctures ; 

 second very broad, nearly flat, with a few fine punctures; 

 third not quite so broad as the second, densely punctured at 

 the base, with transverse zigzag rugae, the apical half with a 

 single line of punctures ; the fourth somewhat raised, espe- 

 cially at the base, smooth, with a few fine punctures; fifth 

 like the third. Apex slightly tinted with blue. 



This species is peculiar on account of the sculpture of the 

 elytra. 



Acmaodera De Geeri, sp. n. 



Our Museum received from Capt, Kerremans' collection 

 two specimens labelled " ceneicollis, De Geer, Transvaal.^' 

 These are distinct from a specimen from Mr. Saunders' 

 collection labelled "ceneicollis, De Geer; compared with 

 type." This latter is the male of viridicenea, as I have 

 already mentioned. 



The two specimens from Transvaal must therefore be a 

 new species. 



It closely resembles A. viridiobnea in form and general 

 appearance. Head bright coppery ; thorax bright coppery 

 red, with the disk dark cyaneous. This dark patch is much 

 narrower than in viridicenea and is obliquely narrowed to a 

 point at the anterior margin ; it is so finely punctured that 

 at first sight it appears quite smooth ; each puncture bears a 

 fine black hair. There is a narrow, punctured, coppery 

 median line. The elytra have the suture and the first and 

 second interstices shining dark cyaneous (extended a little 

 on the third interstice posteriorly), the rest of the elytra 

 bright coppery red. The coppery margin in viridicenea is 

 always narrow. 



The second specimen has the elytra less brightly coloured, 

 the sutural area being brownish coppery and the sides tinted 

 with coppery. 



Long. 12 mm.
