256 PHYSODERA AMPLICOLLIS. 



or perhaps it is more correct to say that they coincide 

 with the hinder angles, and therefore the basal margin is 

 much longer than usual ; the disc with an impressed median 

 line, abbreviated anteriorly and posteriorly, finely rugose 

 aloug the frontal and basal margins, with scattered large 

 punctures at the sides, and in the middle. Elytra mode- 

 rately convex, somewhat swelling out towards the apex, 

 which is broadly truncated , the shoulders strongly roun- 

 ded; finely punctate-striate, the intervals plain, regularly 

 and rather closely punctured, the punctures of the same 

 size as those forming the striae , which are consequently 

 very indistinct. Underside almost smooth. 



This species is very unlike any of the known species, 

 as to colour, sculpture and structure of the thorax.
