( 291 ) XI. Notes on the Euchalcis vetusta, Dufour (Fam. Chal-cididae) ; and on the terminal segments of the females in Halticella and its allies. By Sm Sidney Saundebs, C.M.G. [Part I.— Read February 1st, 1882.] Plate XII. In the recently published 3e trimestre of the 'Annales de la Societe Eiitomologique de France,' 1881 (6e serie, tomel), M. Edmond Andre, m his " Notes Hymenopterologiques " (p. 333), has revised the sectional divisions introduced into the genus Chalcis of Fabricius, which, for the reasons adverted to, he would restrict to three ; namely, (1) Chalcis proper; (2) Smicra, Spinola ; and (3) Halti-cella, Spinola. To this last he refers the genus Euchalcis of Dufour, who described four species from Spain in the aforesaid 'Annales' for 1861 (4e serie, tome 1, p. 9; pi. 1, figs. 4 — 7, and figs. 8 — 10). The third species — his E. vetusta, taken by himself near Saragossa — is thus characterised : — " Euchalcis vetusta, Duf. Atra, nitida, subtiliter punctata ; capite subtriangulari ; scutello con-vexo subrotundato acute bispinoso ; metathorace utrinque bispinuloso, albo-sericeo punctato ; tegula rufa ; alis fumosis, basi punctoque in medio subcostali diaphanis ; abdomine conico, acutissimo, subtrigono, levi, ferru-gineo, apice nigro ; pedibus nigris, tarsis fuscescentibus ; femoribus posticis subtus ad basin obtuse bidentatis. Long. 3 lin." " Mense martio 1811 capiebam banc speciem Zaragoza circa." To this he appends the following remarks : — " Cette espece di Euchalcis, dont j'ai conserve une description suffisament detaillee, n'est plus en mon pouvoir. Elle passa en 1815 dans la collection de Latreille, et de la je ne sais ou. Elle a tons les caracteres indiques dans le signalement generique." In our Transactions for 1873 (p. 414) I described the two sexes of an allied species, under the name of Halticella osmicida, found in Epirus, within the desiccated TRANS. ENT. SOC. 1882. — PART II.
