loth not twice as avIJc as the 4th ; 11th jouit rather long", 

 j)()intcHl and obHqiiely sinuate at the extremity. Man- 

 dibles short, pitchy. Head ahnost as broad as the thorax, 

 oblong, nearly straight at the sides, the hind angles 

 rounded, above very densely rugose-punctate, quite dull, 

 brassy black, the pubescence dense, especially at the back; 

 beneath it is shining and rather closely j)unctured, the 

 punctures coarser in the middle than at the sides, a narrow 

 line in the middle smooth. Thorax considerably narrower 

 than the elytra, one and a half" times as long as broad, in 

 the middle slightly broader than at the base, then nar- 

 rowed to the front, oblique impression rather distinct, a 

 space along the middle smooth ; the sides closely and very 

 finely punctured, the pubescence rather dense. Elytra 

 about as long as the thorax, closely and very finely punc- 

 tured, brassy black like the thorax. Hind body finely and 

 moderately closely punctured, brassy black, pxibescent. 

 Legs nearly black ; tibite on the insides with a grey 

 pubescence. 



Fonteboa and Ega ; two specimens, probably females. 



Agrodes. 



This genus was established by Nordmann for an elegant 

 South American species, but Avas united with Sterculia 

 by Erichson. The genus appears to me, however, to be 

 80 distinct, that I have used Nordmann's name as indi- 

 cating a separate genus. The differences in the trophi 

 from Sterculia {Arceocmemis, Nordinann), are acconq)a- 

 nied by a mai'ked distinction in the form of the head, and 

 by a greater development of the prosternum in Agrodes, 

 and these appear to me sufficiently important and constant 

 to justify the acceptation of Nordmann's two genera. The 

 species of Agrodes appear to be excessively rare ; so much 

 so, that I have never seen any other specimens of it than 

 the two individuals here described as two distinct new 

 species.
