Show 1893.] HYMENOPTERA OF THE FAMILY ODYNERID^E. 687 ODYNERUS COLOCOLO. Odynerus colocolo, Sauss. in Gay, p. 566 (1852). This must be a notable species if specimens agree with the description. ODYNERUS SUBPETIOLATUS. Odynerus subpetiolatus, Sauss. Vesp. i. p. 162 (1852). Odynerus coarctatus, Sauss. in Gay, p. 565 (1852). De Saussure published two descriptions of this species almost simultaneously, but he states that the name of 0. petiolatus was published first. This species is common in Central ChUe. It is very much like 0. labiatus, but smaller and has no tubercle beneath the second abdominal segment. ODYNERUS TUBERCULATUS. Odynerus tuberculatus, Sauss. in Gay, p. 564 (1852). Allied to 0. humeralis, but smaller, with a small tubercle on the upper surface of the first abdominal segment; differs also in the form of the metathorax and in colours. This species must be very rare, as I have looked for it for many years and have obtained only one specimen, which I caught near Valparaiso. ODYNERUS TUBERCULIYENTRIS. Eumenes tuberculiventris, Spin. 1. c. p. 267 (1851). This common little species is easily recognized by its large tubercle on the underside of the second abdominal segment in both sexes, and by the yellow coxae of the males. ODYNERUS MOLING. Odynerus molince, Sauss. in Gay, p. 562 (1852). Odynerus molinius, Sauss. Vesp. iii. p. 251 (1854). Described from a single specimen, female, said to exist in the Paris Museum. From the description it would appear to be allied to 0. labiatus, perhaps a variety. ODYNERUS LABIATUS. Odynerus labiatus, Haliday, Trans. Linn. Soc. xvii. p. 323 (1837). Odynerus lachesis, St.-Farg. Hym. ii. p. 667 (1841). Odynerus marginicollis, Spin. 1. c. p. 256 (1851). One of the most common Chilian species. ODYNERUS CAUPOLICANUS, sp. nov. Allied to 0. labiatus, but with yellow tegulae and yellow markings on scutellum, postscutellum, and metathorax. 3. Head and thorax coarsely punctured, clothed with short, reddish hairs, dull black; abdomen finely punctured, velvety. Antennae and legs ferruginous, tarsi and coxa? darker. Post- |
