1894.] COLEOPTERA OE THE GENUS UiDIOjSYCHIS. 611 



Of broadly robust shape, the head black, with a narrow flavous 

 margin near the eyes, and a few fine punctures ; clypeus and 

 labrum black ; antennas not extending to the middle of the elytra, 

 black, the third joint shorter than the fourth ; thorax three times 

 broader than long, the anterior margin deeply concave, the pos- 

 terior one slightly rounded, sides strongly rounded in front, 

 nearly straight at the base, the anterior angles thickened and 

 produced into a short tooth pointing outward, the surface im- 

 punctate, flavous, the middle with a short irregular-shaped black 

 spot ; scutellum black ; elytra strongly convex, closely and rather 

 strongly punctured, the interstices somewhat wrinkled, testaceous, 

 the suture narrowly black ; underside and legs black. 



Hab. Brazil, Sta. Catharina. 



From the species having uniform pale elytra, the present one 

 may be known by the black suture, the spot on the thorax, and 

 the black head. 



OEdionychis discicollis (Clk. Catal.). 



Black, the margins round the eyes, the basal joints of the 

 antenna?, and the margins of the thorax testaceous ; elytra 

 very finely punctured, testaceous or flavous, the suture, two 

 elongate spots at the base, a transverse spot below the middle and 

 another near the apex black ; the base of the anterior femora and 

 tibiae flavous. 



Var. Thorax testaceous, with a black spot on the posterior 

 margin. 



Length 2| lines. 



Head impunctate, piceous or black, the margins round the eyes, 

 the clypeus, and the palpi testaceous ; frontal tubercles transverse, 

 strongly raised ; antenna? black, the lower two or three joints 

 testaceous, third and fourth joints elongate, equal ; thorax three 

 times broader than long, short and nearly parallel, the sides 

 rounded in front, straight at the base, the anterior angles not 

 produced outward, the surface impunctate, testaceous, with a 

 transverse black band across the disc, the anterior margin of 

 which is indented at the middle, the sides of this band extend as 

 far as the flattened portion of the thorax ; scutellum black ; elytra 

 extremely finely punctured (the punctures in some specimens 

 scarcely perceptible), testaceous, the suture, two spots at the base 

 (sometimes confluent), a subquadrate larger spot below the middle, 

 and another smaller one near the apex black, none of these spots 

 extend quite to the sutural or lateral margin ; elytral epipleura? 

 testaceous ; underside and legs black, the greater part of the base 

 of the four anterior femora and their tibia? flavous. 



Hab. Brazil, Therezopolis. 



Allied to 0. spilota, Baly, but differing in the colour of the 

 thorax and the nearly impunctate elytra.
