apex of each elytron flavous. Boch^ below densely clothed with 

 silvery pubescence ; base of all the femora and apex of the tibiae 

 fulvous. Prosternum longer than broad, longitudinally depressed. 



Hah. Pi'ov. Goyaz, Brazil. 



Allied to G. prcetextatus Suff., but with finely and closely 

 punctured thorax and totally difierent elytral puncturation, the

 suture, a humeral and lateral spot below middle, black ; apex of 

 tibiae and the tarsi black. 



Length 6 millim. 



Head rather closely punctured near eyes and at anterior 

 portion, middle with a longitudinal groove, emargination of eyes 

 very broad, base of antennae with a black spot ; vertex with a 

 divided sinuate black transverse band ; antennae long, black, third 

 joint shorter than fourth, terminal joints widened. Thorax 

 scarcely twice as broad as long, lateral margins slightly rounded

 femora strongly thickened ; prosternum flavous as well as the legs, 

 the first-named subquadrate, narrowed posterioi-ly, rather strongly 

 sulcate. 



Hah. Sfio Paulo, Brazil. 



Somewhat similarly coloured as G. conspurcatits Suff., but 

 diflferently marked, and separated from this species and G. ahstersus 

 Suff. by the entirely different elytral sculpturing, in which there 

 is scarcely a trace of an ari^angement of the punctures in rows. 



Griburius femoratus, sp. n. 



Black ; labrum, three spots on the head, and lower margins of 

 the femora yellowish white ; thorax strongly punctured ; elytra

 patch. 



Length 5 millim. 



Head strongly and closely punctured, black, a narrow, short, 

 transverse stripe between the eyes and a small spot at the 

 emargination of the latter yellowish white, labrum of the same
