Most nearly allied to Ps. viridicuprea, Saund., but very 

 distinct from all the species of the genus by the strong 

 costse on the elytra. Head very rugose. Thorax about 

 one-third broader than long, narrowed anteriorly, espe- 

 cially in front of the middle, with a smooth central line ; 

 the disk not thickly punctured; the sides rugosely punc- 

 tured, the punctures golden-green. Elytra three times 

 and three-quarters longer than the thorax, but scarcely 

 wider at the base, gently narrowed from the shoulders to 

 the posterior two-thirds, and then more suddenly narrowed 

 to the apex; each elytron with four black shining costte, 

 the interstices rough, and rather thickly punctured, the 

 punctures green. The whole under side coppery, frosted ; 

 middle of the sterna smooth.

The whole ^upper surface is closely and very finely 

 punctured, which renders the larger punctures (especially 

 on the elytra) less well defined. The head and thorax 

 are somewhat thickly punctured with the larger punctures; 

 the latter is obliquely narrowed in the anterior third; 

 the sides parallel for the posterior two-thirds; the anterior
