Hosts. — Nothing has been recorded on the habits of this species. 



Lesne (1899) described brasiliensis from a series of specimens from 

 many localities in southern Brazil without designating the type local- 

 ity, and these types are scattered in many different European 

 collections.

Male. — Dark reddish brown to brownish black, elytra, antennae, 

 palpi, and tarsi usually paler. 



Head rather densely, coarsely punctate and with a few short, recum- 

 bent, inconspicuous hairs on clypeus and front of head, with long, 

 longitudinal, parallel costae on occiput : clypeus deeply, arcuately 

 emarginate in front: clypeal suture obsolete: labrum finely, densely 

 punctate. 



Pronotum slightly transverse, widest at middle: sides broadly 

 rounded, more strongly converging anteriorly, with a small, broad 

 tooth at apical angles: posterior angles broadly rounded: surface 

 sparsely clothed with short, erect and recumbent, inconspicuous hairs. 

 coarsely, sparsely punctate on basal half, rather densely, irregularly 

 dentate on apical half, the teeth broad, variable in size, semierect. and 

 rasplike. 



Elytra at base vaguely narrower than pronotum at middle : sides 

 nearly parallel, conjointly broadly rounded at apices: apical contour 

 (when viewed from above) obtusely rounded: surface not very deeply 

 depressed along sutural margins on apical declivity, coarsely, rather 

 densely punctate on disk, coarsely, confluently punctate and rugose on 

 apical declivity, sparsely clothed with short, recumbent, yellowish hairs 

 on apical half: sutural margins on apical declivity strongly gibbose 

 but not distinctly expanded laterally at middle of declivity, coarsely 

 rugose on dorsal surface, sides abruptly deflexed, the gibbosity gradu- 

 ally, broadly rounded when viewed in profile. 



Abdomen beneath coarsely, densely punctate, sparsely clothed with 

 short, recumbent, yellowish hairs : last visible sternite broadly rounded 

 at apex, rather densely clothed with moderately long, recumbent and 

 erect yellowish hairs.

 sternite smooth at the apex, with a small depression in front of the
