 of the eyes hollowed out and hairy. Antennge (male) longer 

 than the body; five last joints sharp edged and compressed; ter-

 tudinally on the upper side. Thorax ferruginous, thickly punc- 

 tured ; a smooth band extends down the middle, arising from the 

 fore margin, dilated on each side about the middle ; behind the 

 dilatation it is twice as wide as before, and falls behind into a 

 smooth transverse space on the hinder edge of the thorax ; on 

 each side of the thorax are three depressions, the two hindermost 

 placed nearly transversely and scarred in the centre. Scutellum 

 blackish and acuminate at the tip. Elj'tra polished, with many 

 scattered punctm-es, only visible in some lights ; the surface is 

 highly iridescent, sinning with a yellowish metallic green ; when 

 the light does not shine on the elytra, they seem of a pale ferru- 

 ginous. Under sides of body pale ferruginous, the sides covered 

 with silky pubescence. Legs with the coxse black, inside rather 

 thickly clothed with ferruginous hairs, tarsi black, soles with fer-
