BuprestidEey^-om Damma Island. 411 



Buprestidaj are certainly new, and of these I subjoin descrip- 

 tions. In order to make tlic position of one of these clear I 

 nnist first make some remarks on the following genera : — 



Chrysodema, Pseudochrysodema, and Paracupta. 



The &}oecies of Chrysodema have metallic tarsi and have in 

 nearly all cases a smooth, slightly raised, median line to the 

 thorax. 



The species of Paracupta have yellow tarsi and an impressed 

 median line to the thorax. 



Fseudochri/sodeina, Saund. (Cist. Ent. i. p. 223), occupies 

 an intermediate ])lace between these, having yellow tarsi, but 

 having a raised median line to the thorax ; it has, moreover, a 

 distinct projecting angle to the elytra just below the shoulder. 



The interesting species which I describe below has yellow 

 tarsi and a raised median line to the thorax, and has also a 

 subhumeral angulation. In these respects it comes nearest 

 to Pseudochrysodema ; it has, however, quite a different 

 appearance from the two described species, liaving evenly 

 convex elytra, the thorax with scarcely any trace of lateral 

 impression, but at the base of the thorax are two small, elon- 

 gate, sharply cut foveae, which are not present in Pseudo- 

 chrysodema nor in any species of Chrysodema known to me. 

 I think, nevertheless, that it would be premature to pro[)jse a 

 new genus for the present species. 



Pstudochrysodema (?) Walkeri^ sp. n. 



Aureo-viride, nitidum ; thoraco subtiliter punctulato, liaea mcdiana 

 vix elevata loevi, lateribus leviter imprcssis crebrius punctatis, 

 basi utrinque fovea parva insculpta ; elytris nigro-cyaneis, coii- 

 vexis, punctatis, ha\id costatis, ad apiccm bene acuraiuatis acute 

 scrratis ; tarsis fiavis, unguibus a3neis ; antenuia articulis y-lL" 

 nigris. 



Long. 15 lin. 



The thorax is gently convex, only slightly narrowed in 

 front, finely and not very closely punctured on the disk, more 

 closely and rather more strongly punctured at the sides, which 

 are very lightly impressed at the middle; there is a smooth 

 slightly raised median line, with the usual impressed punc- 

 tured line on each side of it ; the posterior angles are nearly 

 right angles, and do not project laterally ; on each side of the 

 base, at a short distance from the posterior angles, there is a 

 short, oblique, narrow, deeply impressed fovea. I'he elytra 

 are convex, most so at a short distance from the base, with »
