The excellent and accurate drawings of the author, representing all thespecies, are unfortunately much disfigured in the lithographic press.
Notonectides.—E ieber (ibid. p. 11) has given a monograph of thegenera Sigara and Ploa. Sigara contains six species, S. mimtissima, L., andthe Sardinian 8. leucocephala, Spin., along with four species collected byHeifer in the East Indies, S. grisea, striata,, lineata, punctata. Ploa com-prehends four species, two from the East Indies, PL frontalis and lihirata,and one North American, PI. striola, being associated with the Europeanspecies, P. minutissima (Notonecta ), Eabr.
Eulgorellj®.—W estwood (Arcan. Ent. pl.71), has figured some Ame-rican species, Eulgora ( Episcius) amabilis, Westw. (Ann. Nat. Hist. 1842),from Mexico ; Lystra combusta and Cladopteryx obliquata, new species fromColumbia. Another new species from Erazil, Diloburd subocellata Westw.,is described in a note.
