Stuphi/linulie of the Amazon Valley. 2-45 



Elytra sliglitly longer than the thorax, shining, the apical 

 half yellow ; in front of this infuscate, but the extreme base 

 reddish ; along the suture with a row of punctures, and 

 towards the side Avith three or four other indistinct rows, 

 which become obsolete before the extremity. Hind body 

 reddish, densely and very finely punctured, dull, the punc- 

 tuation of its imder face similar to that of the upper. 

 Legs pale yellow. 



Tapajos ; four females. 



This species greatly resembles the four preceding ones 

 {deletum, pictum, integrum and hilare), but is a little 

 larger, and may be easily enough distinguished by the 

 more even distribution of the punctures on the head.
