South American EwmolpidiB. 477 



Hah. Amazons. 



Closely allied to (J. inquinata, Lef. (according to Lefevre, 

 who examined the insect), but the elytra without any basal 

 depression, and the femora metalhc green, not blackish at 

 their posterior half. 



Colaspis vcnczueliB, sp. n. 



Fulvous below, the antennae (the basal joints excepted) and the 

 apex of the posterior femora blackish, above metallic green, thorax 

 angulate at the middle, very closely and rather strongly punctured, 

 elytra deeply and irregularly punctured, the interstices everywhere 

 strongly transversely rugose, costate at the apex. 



Length 4 millim. 



Mas. Head strongly and rather closely punctured, metallic-green, 

 clypeus of similar sculpture at the base, nearly impunctate anteriorly, 

 its anterior edge nearly straight, labrum fulvous, palpi pale fulvous, 

 the terminal joint piceous, antenna3 black (the last three joints 

 wanting), the lower tliree or four joints fulvous below ; thorax one- 

 half broader than long, the sides angulate at the middle, tlie surface 

 very closely and evenly punctured, the middle of the disc with a 

 narrow less closely punctured space ; elytra with strongly raised 

 transverse rugosities throughout, the interstices deeply punctured, 

 the punctures forming two more regular rows near tlie suture, the 

 interstices near the apex longitudinally costate; below and the legs 

 fulvous, the apex of the posterior femora black ; flanks of the thorax 

 strongly punctured. 



Hal. Venezuela, Ceara. 



This species seems still more closely allied to C. inquinata 

 than the preceding one, on account of the fulvous imder- 

 side, which, however, is without metallic gloss. The closely 

 and evenly punctured thorax will, however, at once dis- 

 tinguish the insect from the last-named species. Canccps, 

 Lef, has a distinct olytral depression and quite a different 

 sculpture. 



C'ola.yiis porom, sp. n. 



Oblong-ovate, black, with a sliglit violaceous tint, the head and 

 thorax fulvous, very finely and closely punctured, elytra extremely 

 closely and strongly punctured, the interstices finely wrinkled or 

 reticulate. 



Length 5^ millim.
