Novo Friburg, Kio Janeiro {coll. Dr. Baden). 



Head coarsely punctured, black; mouth pitchy. Eyes 

 (male) nearly touching in front the median line. Antennae 

 very slightly thickened towards the tip ; joints from the fifth 

 distinctly enlarged at apex and serrate. Thorax strongly 

 transverse, rounded, transversely convex in the middle, the 

 convexity clothed with long, erect, black hairs, partially gla- 

 brous and punctured behind. Elytra cuneiform, short, reach- 

 ing only halfway down the first abdominal segment, black, 

 brownish and punctured on the disk, with a line of long, erect, 

 black hairs curving from the base to the middle of the suture. 

 Legs pitchy black, hairy, short, except the elongated hind 

 pair, of which the femora are much thickened, and have a di- 

 stinct tuft of black hairs on their upper edge and a fringe be- 

 neath. The tibife have their apical half reddish, with two 

 tufts of tawny hairs on their outer edge, and a continuous 

 long fringe of similar hairs on their inner edge ; the tarsi of 

 the same legs are also reddish ; the anterior femora are bearded 

 underneath with long black hairs. Body beneath black ; me-
