his insect thus appears to differ from that of Eabricius, who says 

 " pedes paliide femoribus basi nigris." Forster regarded them as 

 distinct; and as Fabricius merely gave a brief diagnosis in his 

 Syst. Piez. p. 157, and this apparently founded on Panzer's 

 figure, Forster was not unnaturally misled into redescribing and 

 renaming the Fabrician instead of the Panzerian insect.

There seems to be some error about this species, as the descrip- 

 tion does not well agree with the figure. Judging by the figure, 

 I would refer EucJiaris festiva, Fabr., E. rapo, Walk., and 

 Schizaspidia maculata, Westw., to this genus. All these are 

 South-American insects.
