often obscure and ill-defined ; for example, Lcpronota and 

 Teaspes cannot be structurally separated. Cliapuis gives 

 as the distinguisbing cbaracters, tbe strongly tuberculate 

 elytra and deeply cbannelled tibioe of the first-named 

 genus; and the pubescence of the upper surface and the 

 simple tibiae as peculiar to Teaspes; but even his type of 

 the latter genns T.morhillosa has very distinctly channelled 

 tibia.^, while T. lugubris, Lefev., has impubescent elytra ; 

 on the other hand many species of Lcpronota have smooth 

 elytra and some are pubescent. Aghalus, another genus 

 included in this section, is given by Chapuis as having 

 mucronate tibice, but this is only the character of the 

 male insect, although the shape of the thorax is rather 

 characteristic and differs from tliat of most of the other 

 genera. 



Lcpronota discoidalis, sp. n. 



Obscure aeneous, the antennae and legs ferruginous, thorax very 

 finely punctured, elytra finely punctate-striate, the disc seneous, 

 the sides broadly ferruginous, femora ajneous at the base. 



Length 4 niillim. 



Head remotely and finely jmnctured, aeneous, labrum obscure 

 fulvous, antenna} entirely ferruginous, extending to the middle of 

 the elytra, the terminal joints robust but elongate, thorax nearly twice 

 as broad as long, the sides rounded, the posterior margin broadly 

 rounded at the middle, the surface very minutely and closely 

 punctured ; scutellum impunctate, greenish ; elytra with a rather 

 deep depression at the sides below the base, finely punctate-striate, 

 the punctures larger at the base, the disc, in shape of a broad 

 posteriorly narrowed band, reneous, the sides and the epipleurce 

 ferruginous ; below and the base of the femora greenish-aeneous, 

 the legs ferruginous. 



Hah. South Brazil, Lagos (my collection). 



Distinct from any of its allies by the coloration, but a 

 true Lcpronota. I possess a single male specimen. 



Aghalus nigroviolaccns, sp. n. 



Black, with a slight violaceous tint, the lower joints of the 

 antenna; fulvous, legs bluish, thorax extremely minutely and closely 

 punctured ; elytra with basal depression, not more strongly punctured 

 than the thorax, except within the depression. 



Mds. Posterior tibite with a long projection near the apex, furnished 

 with loner fulvous hairs.
