yellow. Palpi yellow ; mandibles red. LaLrum ]iitcliy, 

 "With a small notch in the middle ; on either side of this a 

 little prominent, and ontside the ])romiuence sli<i;htly 

 emarginate. Head dull blackish, with the neck red ; the 

 surface finely coriaceous, sparingly and finely punctured. 

 Thorax narrow, a good deal longer than broad, scarcely 

 narrowed behind, bright red ; finely and sparingly ]iunc- 

 tured, with an impunctate space along the middle. Elytra 

 ])arallel, with the shoulders distinct, a little longer than 

 the thorax, rather finely, moderately closely punctured, 

 bluish or greenish. Hind body red, with the apical seg- 

 ments infuscate. Legs yellow ; the apex of the hind 

 femora distinctly, of the middle ones less distinctly, infus- 

 cate. 



In the female the ventral })late ot the 7th segment of the 

 hind body is produced, so as to form a projecting triangle 

 at the extremity ; the apex of this triangle is scarcely 

 pointed, the sides do not project in the form of teeth. 



Ega and Tapajos ; several individuals. 



This species greatly resembles om* European P.fiiscipes, 

 but is remarkably easily distinguished therefrom by the 

 coriaceous surfiice of the head ; it has also the antennas and 

 palpi differently coloured, these being clear yellow, and 

 the elytra are less closely and distinctly punctured.

Antennas 1^ lin. in length, the three basal joints

 10th much longer than broad. Mandibles red, infuscate 

 at the ai)cx ; ])alpi red, infuscate towards the extremity. 

 Head narrow, only about half as broad as the elytra, much 

 narrowed behind the eyes, so that the constriction at the 

 neck is but little ; it is black in colom-, with a blue tinge on 

 its u])i)er side ; it is rather closely ])unctured, except on the 

 middle of the hinder half, where the ])unctures are but 

 sparing. Thorax small, greatly narrower than the elytra; 

 towards the front it is a good deal narrowed ; it is red in
