The insect is of bronze color, a purple reflect appearing on 

 the back in irregular patches as the light may fall upon it. 

 The palpi and the base of the antennas are of yellowish color, the 

 apex of the third joint of the maxill. palpi, however, as well as 

 that of the second, third and fourth antennal joint is brown, of 

 which color is also the remaining part of the antennas. The 

 second antennal joint is the shortest, the third and fourth are 

 rather longer than the following. The mandibles are rather 

 straight and porrected. The sides of the thorax are almost an- 

 gular and furnished with a setigerous puncture at the broadest 

 part, that is, just before the middle. There are seven distinct 

 rows of punctures on either elytron and an accessory one 

 along the side of the scutellum, the rows decreasing in length 

 towards the margin and the punctures in depth towards the 

 apex, the first row on either side ; changing however, before 

 the apex into a furrow which falls in with that which sepa- 

 aates the margin from the rest of the elytron. Before and 

 beyond the middle, in the region of the third row of punctures, 

 is an excavation containing a puncture which is situated upon 

 the third interstice. The excavation nearest the base is the 

 deepest. The apex of the elytra is marked with a spot of
