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
