defoliated the plant
and
ate large patches of the barkbesides.Mr.
Schwarz

I proposed thisgeneric term in 1897for theCochlidian species argentijlua
Geyer and argyrorrhea
Hiibner, but gave no exact characters. I havenow
beforeme two male
specimensofargen- tiflua fromCayamas
(E.A. Schwarz), and
Santiago,Cuba
(Capt.
Wirt
Robinson),and
givefrom them
the generic characters. In Ent.
Cubana,
p. 274,Gundlach
refers to this species*Reportof Entomologist andBotanist,from Ann. Kept. Experimental Farms (Canada), foryear1890, pp, 154-188.
