Cacoscelis fimbriata (Chevr.). 
C. elongata, parallela, rufa; elytris nigris: caput arcuate foveolatum, im- 
punctatum: thorax subtiliter et sparsim punctatus: elytra crebre punc- 
tata, nigra: antenne rufo-fusce, art. 1-3 flavescentibus: pedes et 
corpus subtus rufi. 
Long. corp. lin. 3, lat. lin. 12. 
C. fimbriata may be separated from the Mexican species, C. bico- 
loraria, by the coarse and close punctuation of the elytra; its very 
parallel, subattenuate form will distinguish it from the Brazilian 
species, C. nigripennis. 
Bolivia. 
Cacoscelis bicolorata. 
C. nigra, prothorace rufo-flavo: caput transverse foveolatum, impunctatum: 
thorax impunctatus: elytra leviter punctata: antenne rufo-fusce, art. 
1-8 flavis: pedes et corpus subtus nigri; femoribus anticis flavo adum- 
bratis. 
Long. corp. lin. 4, lat. lin. 13. 
This Mexican species. may be separated from its congeners by its 
finely not coarsely punctate elytra. 
Mexico. 
Cacoscelis nigripennis. 
C. parallela, nigra, prothorace rufo: caput super oculos transverse etiam- 
que longitudinaliter foveolatum, impunctatum, flavo-rufum: thorax 
leviter punctatus: e/ytva satis parallela, creberrime punctata: pedes et 
corpus subtus nigri: antenne nigro-fusce, art. 1-3 subtus flavescentibus. 
Long. corp. lin. 83, lat. lin. 13. 
C. nigripennis approaches C. fimbriata; it is distinctly broader, 
and the legs and under side are black. It is separated from C. bico- 
loraria by the coarse punctuation of the elytra.
