coarsely but not densely punctured ; front tarsi infuscate- 

 yellow. 



St. Paulo ; two individuals, ^ and 2 . 



Apart from its beautiful colovu*, this species, though 

 clothed Avith long black sette, is remarkable for the very 

 scanty pubescence of the upper surface. 



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

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

 tibus ; palpis antennarumque articulis basalibus testaceis, 

 his intus infuscatis, tarsis anterioribus fusco-testaceis ; 

 capite thoraceque fortiter inrequaliter, elytris parcius sub- 

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

 lin. (vix). 



Mas latet. 



Elongate and narrow; antennae rather slender, \\ lin. in 

 length, not thickened towards the extremity, black, with 

 the two basal joints yellow, bvit infuscate inwardly ; 3rd 

 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 4f long) ; it is a little 

 rounded at the sides, and slightly narroAved behind, 

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

 but unequally covered Avith punctures, the punctures 

 Avanting on a space on each side near the fi'ont angles, 

 also on a A-ery 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, 

 punctured. Elytra quite 1^ 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 

 toAvards the extremity Avith the setse shorter and coarser ; 

 on the under surface the punctuation of the basal segments 

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