ON LEDRA PERDITA, A. & S.

Extract

On page 577 of their great work on the Hemiptera, Amyot and Serville describe two species of Ledra. One, L. aurita, the well-known species of Europe, was characterized from specimens collected near Paris. I have specimens of it now before me. Its size, the broad membranous prolongation of the head, the ear-shaped horns on the thorax, together with other details of structure, separate it widely from any other homopterous insect. The other species described, L. perdita, though equally unique in form, was characterized under circumstances which, for such eminent scientists as Amyot and Serville, seem extraordinary. After a three-line description, they remark: “L'exemplaire unique d'après lequel cette espèce a été figurée, ayant été détruit, nous la décrivons d'après la figure.” Unfortunately, the figure, number five on plate II., is very poor. The species is credited to “Amérique septentrionale.”
