A. G. Butler (Tr. E. Soc. 1872, pp. 49-58) catalogues the described 
species of Pericopidcs of the genera Bsthema, Eacyane, Composia, PJialoesia, 
Stenelcj Ilyalurga, Gyara, Ilyclosia, Phaloe, and Pcricopis, Pericopis dis-^ 
juncta, Walk.,=P. bivittata, Walk. Daretis marginalis, Walk., is a Pet'i- 
copis, and perhaps=P. dissimidans, Walk., $. P. lunifera, Butl., =

a Phaloe, near P. cruenta ; C. phoeha probably =Ptfnco/>is isse, var. ; C. aorsa 
probably = P. hivittata j C. iscariotes, felderi, and helicon[io']ides are probably 
new.
