DESCRIPTIONS of NEW SPECIES of SOUTH AMERICAN 

 PHYTOPHAGOUS COLEOPTERA. 



By Martin Jacoby, F.E.S. 



(Concluded from p. 250.) 



Nodojwta venezuelensis, sp. nov. 



2 . Dark aeneous ; the antennae, tibiae, and tarsi more or less 

 fulvous ; thorax finely punctured, the sides closely aciculate-punctate ; 

 elytra very finely geminate punctate-striate, with basal depression, the 

 sides with three or four more or less interrupted costae. 



Var. Antennae and legs dark aeneous. Length, 3-3^ mill. 



Head strongly and remotely punctured ; the clypeus distinctly 

 separated, punctured like the head ; antennae short and robust, the 

 terminal joint strongly thickened, the apex of each stained with 

 fuscous ; thorax twice as broad as long, narrowed in front, the sides 

 rounded, oblique, the surface closely and finely punctured at the sides, 

 less closely at the disc, the interstices extremely finely granulate and 

 sparingly impressed with minute punctures ; scutellum impunctate ; 

 elytra distinctly transversely depressed below the base, the latter rather 

 strongly punctured in double rows, the posterior portion very finely 

 and more remotely punctate, the shoulders in shape of an elongate 

 tubercle, followed by another rounded one before the depression, the 

 sides below the latter with four or five costae, which do not extend much 

 below the middle, and are sometimes interrupted into several elongate 

 tubercles, the apex of each elytron rather pointed. 



Hab. Venezuela. 



I only know the female of this species, which seems closely 

 allied to N. singularis, Lefev., likewise from Venezuela ; but this 

 author describes his species as having the head alutaceous and 

 finely and remotely punctured, and the elytra as punctured in 

 rows, and says nothing about a geminate punctuation ; nor does 

 he describe any costae at the sides, but elongate tubercles instead. 

 The antennae in the present insect are moreover without single 

 erect hairs at each joint, as Lefevre describes N. singularis. 

 N. costipennis, Lefev., differs in the scarcely perceptibly punc- 

 tured thorax, and other details. 



Nodonota boliviana, sp. nov. 



$ . Black ; head and thorax distinctly but not closely punctured ; 

 elytra rather irregularly punctured in rows, the latter partly geminate, 

 distinct to the apex. 



? . Elytra very finely punctured, with a single small tubercle at 

 the sides. Length, 3-3^ mill. 



Head very sparingly and finely punctured, sometimes with a 

 metallic gloss, the epistome somewhat obsoletely separated from the 

 face by oblique grooves ; the antennae black, the lower five joints 

 fulvous, the basal joint staine with black above ; thorax twice as
