458 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, 



Oedionychis torquata, sp. n. 



Testaceous, tlie terminal Joints of the antennae and the breast 

 piceous ; head strongly punctured ; thorax impunctate ; elytra 

 distinctly punctured, with three small black sjDots, two at the base 

 and one at the middle of each el}'tron. 



Length 6 millim. 



Rather flattened above, the head very strongly and deeply 

 punctured ; frontal elevations transverse, strongly raised, nearly 

 contiguous ; carina short and rather broad ; antennae testaceous, 

 the terminal joints more or less piceous, third and fourth joints 

 equal, apical joints shorter ; thorax twice as broad as long, the 

 sides rounded and broadly flattened, anterior angles not prodviced 

 outwards, the surface impunctate, obsoletely transversely grooved 

 at each side near the base ; elytra slightly widened towards the 

 middle, very closely and distinctly punctured at the base, rather 

 more finely so below the middle, the spots placed as in 0. hume- 

 ralis Fab., one at the shoulders, one near the scutellum, and the 

 third of oblique shape at the middle; the breast nearly black ; 

 legs testaceous, as well as the abdomen. 



Hah. Brazil. 



I must separate this species from 0. himieralis Fab., 0. ^-jnmctata 

 Schauf ., and several others with nearly similar elytral markings, on 

 account of the strongly punctui-ed head and the black breast ; the 

 eyes are moderately large and widely separated, 



Oedionychis decora, sp. n. 



Narrow and subdepressed, testaceous ; antennee black, the basal 

 and the terminal three joints pale ; thorax impunctate, the anterior 

 and posterior margins fuscous at the middle ; elytra nearly im- 

 punctate, each with two basal elongate spots, a transverse band at 

 the middle, and another spot near the apex, fuscous. 



Leng-th 5-6 millim. 



Head impunctate, testaceous or pale fuscous ; eyes very large ; 

 frontal tubercles trigonate, nearly joined ; antennse scarcely 

 extending to the middle of the elytra, black, the basal joint 

 testaceous, the terminal three joints obscure flavous, third and 

 following joints equal ; thorax flattened, rather more than twice as 

 broad as long, the sides rounded, broadly flattened, the base (in 

 one specimen) with an obsolete transverse groove, the disc im- 

 punctate, testaceous, the anterior and postei-ior margins fuscous at 

 the middle, anterior angles acute but scarcely produced ; elytra 

 not perceptibly punctui-ed, testaceous, with four fuscous or piceous 

 marks — an elongate one on the humeral callus, a rounded spot near 

 the scutellum, a short transverse band at the middle, and another 

 larger rounded spot near the apex ; under side and legs testaceous. 



Hah. Amazons ; also Peru. 



I may add that the suture of the elytra is sometimes also 

 narrowly marked with fuscous, and that the central band has 

 a short and narrow stripe attached to its outer end, pointing 

 downwards.
