This scries is quite uniform in size ami color, the only appreciable 

 variation being in the color of the antcnnic and of the caudal tibiae. 

 The antennae are uniform ochraceous in some individuals, of the same 

 color slighth' washed proximad with umber, there narrowly annulate 

 with paler in others and also uniform umber annulate through the 

 length but more distinctly so proximad. The color of the eyes vary 

 from ochraceous to deep walnut brown. The caudal tibiae are strongly 

 purplish-pink in some specimens, in others whitish and numerous speci- 

 mens are lightly washed with pinkish. 



The typical specimen from Rio Grande do Sul mentioned in a previous 

 paper^^ has the median carina of the pronotum more elevated than the 

 Sapucay specimens.

These specimens are cjuite uniform in size and coloration, in a few 

 the yellowish tint being more pronounced than in others. The carmine 

 caudal tarsi are quite striking.

This species, which has been confused with Serville's tarsata from 

 Brazil, differs from the latter in having less red on the head, the entire 

 portion of the latter caudad of the interocular region being red in 

 tarsata, in having the clypeus, labrum and mandil)les light in color 

 instead of solid black as in tarsata, the cephalic and median limbs 

 variegated wdth yellow, red and olive-green instead of red, orange and 

 black or blackish, and the proximal dark bar on the caudal femora 

 weak and diffuse instead of solid and clearl}^ defined on the dorsal half 

 of the limb. 



Two females of this series have the caudal femora with very 

 weak dark maculations and annulations, the actual color of them 

 being oil green, while the blackish genicular maculations are as dis- 

 tinct as in the other specimens. In some individuals the second joint
