Staphylinida of the Amazon Valley. 307 



coarsely but not densely punctured ; front tarsi infuscate- 

 yellow. 



St. Paulo ; two individuals, $ and ? . 



Apart from its beautiful colour, this species, though 

 clothed with long black setas, is remarkable for the very 

 scanty pubescence of the upper surface. 



3. Tcenodema recta, n. sp. Nigra, nitida, capite, tho- 

 race, elytrisque viridi-icneis, his apicem versus cyanescen- 

 tibus ; palpis antenuarumque articulis basalibus testaceis, 

 his intus infuscatis, tarsis anterioribus fusco-testaceis ; 

 capite thoraceque fortiter ina3qualiter, elytris parcius sub- 

 tiliter, punctatis. Long. corp. 7 lin. ; lat. elytrorum 1 ^ 

 lin. (vix). 



Mas latet. 



Elongate and narrow; antennas rather slender, 1^ lin. in 

 length, not thickened towards the extremity, black, with 

 the two basal joints yellow, but infuscate inwardly ; 3i'd 

 joint about twice as long as 2nd. Palpi yellow ; mandibles 

 pitchy black. Head on the upper surface pale brassy, 

 coarsely punctured, only a narrow transverse space between 

 the eyes being impunctate ; the punctures are umbilicate, 

 each bears a fine pale hair. Thorax nearly as long as 

 broad (about 1 lin. broad, and ^f long) ; it is a little 

 rounded at the sides, and slightly narrowed behind, 

 similar in colour to the head ; the surface is rather closely 

 but unequally covered with punctures, the punctures 

 wanting on a space on each side near the front angles, 

 also on a very small longitudinal space in front of the 

 base in the middle, and more sparing about the margins 

 than they are on the disc ; the punctures are of unequal 

 sizes, the larger ones being umbilicate. Scutellum brassy, 

 pimctured. Elytra quite \g lin. in length, shining 

 metallic, the basal part similar in colour to the head and 

 thorax, the apical part blue ; they are sparingly punctured, 

 the punctures are all fine, those at the base being coarser 

 than the extremely fine ones at the extremity. Hind 

 body long and slender, entirely black ; on the upper side 

 the basal segments are rather coarsely but not closely nor 

 deeply punctured on their anterior portions; the 6th and 7th 

 segments more finely and sparingly punctured, the latter 

 towards the extremity with the setse shorter and coarser ; 

 on the under surface the punctuation of the basal segments 

 is deeper and coarser, but on the 7th segment it is finer
