SOUTH AMERICAN EUMOLPID®. 255 
the lateral edge narrowly reflexed, and obsoletely metallic green. 
Elytra broadly, obsoletely depressed below the shoulder, strongly 
punctate ; subseriate next the suture and costate at the apex ; 
the latter feature as usual most pronounced in the ?, which also 
has a more or less well-defined costa from the shoulder to the 
apex ; the reflexed margin is obsoletely metallic. 
Rhabdopterus rosenbergi, sp. nov. 
Small, stout. Below very dark brown, almost black; above 
dark neous bronze, shining. Legs dark brown, with middle of the 
femora rufous; thorax transverse, much widened at about the middle ; 
sides nearly straight from the base to the middle, then abruptly 
narrowed to the front, giving the appearance of sub-angulation ; 
elytra (2) with sides covered with irregular tubercles and 
rugosities. 
Type, ?, Cachabé, low c., November, 1896 (Rosenberg). 
Length, 4:5 mm. 
Head smooth, except for a few fine punctures on the 
epistome; the cross depression strong; the vertex smooth, 
impunctate or nearly so. Antenne rufous? (four joints missing) ; 
thorax rather obsoletely collared in front, and excessively finely 
and obsoletely punctulaté ; elytra with well-marked transverse 
depression ; finely seriate punctate, obsoletely costate at the 
apex. The sides and more or less of the discal and basal parts 
broken up into series of irregular smooth tubercles or ruge, 
which has the effect of breaking the seriate punctuation ; the 
reflexed margin and the punctuation is obsoletely metallic in a 
strong light. The smooth thorax and tubercular elytra are 
different from any other known to me. 
Podoxenus distortus, sp. nov. 
AAneous bronze, the elytra with a rufous tinge, so they do not 
appear as golden as the thorax, which, in both sexes, especially in the 
dé, is very much puffed up or swollen; transverse, and strongly 
angulate at the middle side, the surface shiny and finely punctured ; 
elytra are coarsely, semi-seriately punctate, transversely rugose on 
the sides, costate and tuberculate at the apex; the anterior and 
middle tibize of the $¢ so bent inwards as to seem almost useless 
for walking. 
Type, ¢ and 9, Ribeirao, Pires, San Paulo, Brazil, 11-19 
(Gounelle). 
Length, 7 mm. 
Head rather sparsely punctured, with well-defined transverse 
and poorly-defined longitudinal marks ; calli smooth and large ; 
antennz rufous, barely reaching the middle of the elytra; the 
thorax is margined all around, the punctuation becoming sparser 
towards the sides, especially the hind angles in the ¢; the scutel
