liis insect thus appears to differ from that of Fabricius, who says 
“ pedes pallide 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 Eucltaris f estiva, Fabr., E. rapo, Walk., and 
Schizaspidia maculata, Westw., to this genus. All these are 
South-American insects.
