metallic green ; below dark fulvous or piceous, the breast stained 

 with metallic green, the legs flavons, the femora thickened, the tibia? 

 simple, claws appendiculate, the prosternum narrowly elongate, 



pubescent. 



Hah. Colombia {Pe.hlhc), Mus. Stettin and my col- 

 lection. 



The above description is that of the male, which may 

 be known, as usually, by the dilated anterior tarsi ; the 

 insect is doubtfully placed by me in the present genus, 

 on account of the scarcely thickened antennas and the 

 pubescent head and thorax, no other species of Alethaxius 

 at present known being similar in structure ; it agrees, 

 however, in the shape of the thorax and that of the 

 prosternum as well as in other details, with those of the 

 genus in question. 



Alethaxius verrucosus, sp. n. 



Obscure fulvous with a slight bluish gloss, the apical joints of 

 the antenna? and the tibia? and tarsi blackish, thorax extremely 

 closely and finely punctured, angulate at the sides, elytra very 

 strongly and closely punctured, the interstices strongly verrucose 

 and rugose at the sides. 



Var. Legs entirely fulvous. 



Length 5-7 millim. 



Head very closely and rather finely punctured, as well as the 

 clypeus, the latter obsoletely separated from the face, antennae 

 black, the lower six joints fulvous ; thorax of equal width, scarcely 

 twice as broad as long, the sides strongly dentate at the middle and 

 angulate before and below the tooth, the surface extremely closely, 

 evenly and finely punctured; elytra deeply and strongly punctured, 

 the punctures irregularly arranged in rows at the suture, forming 

 stria? near the apex, the interstices at the rest of the disc strongly 

 verrucose and rugose, forming a more or less distinct costa near the 

 lateral margin ; legs bluish-black, the femora fulvous at the base. 



Hah. Brazil, St. Catharina. 



The general coloration is a light or dark fulvous with 

 a more or less aBueous gloss; the thorax is extremely 

 closely and finely punctured, offering a great contrast 

 with the elytra, on which the sculpture is coarse, close 

 and irregular with very strongly rugose interstices ; the 

 colour of the legs seems very variable; the tibice and
