Show 1893.] ON HYMENOPTERA OF THE FAMILY ODYNERIDJE. 685 6. On the Chilian Hymenoptera of the Family Odyneridce. By E D W Y N C. R E E D , C.M.Z.S. [Eeceived July 26,1893.] A fairly large number of Hymenoptera of the family Odyneridae exist in Chile, but I have always found a difficulty in determining them on account of the very careless way in which they have been described by Spinola and D e Saussure, in Gay's ' Historia Fisica y Politica de Chile.' Many of the species are described from one sex only, often from single specimens, and several species are described twice over. As I intend shortly to publish a Synopsis of the group, in the ' Anales de la Universidad de Chile,' I have drawn up the following list of the Chilian species. GAZELLA, Spin, in Gay, vi. p. 328. Spinola placed this genus among the Crabronidae, probably on account of its abnormal venation, the second and third cubital cell each receiving a recurrent vein. GAZELLA EUMENOIDES, Spin. This species is very local and far from common. Occurs in the central provinces. ZETHUS DICOMBODA. Epipona dicomboda, Spin, in Gay, vi. p. 250 (1851). This species is not common. Occurs near Valparaiso and at the Canquenes Baths. LABUS SICHELIANUS. Labus sichelianus, Sauss. Am. Wasps (Smithsonian Misc. Coll. xiv.), p. 56, pi. iv. fig. 20 (1875). This species does not exist in any collection in Chde. DlSCOELIUS MERULA. Biscoelius merula, Curtis, Trans. Linn. Soc. xvii. p. 325 (1834). Epipona chilensis, Spin. 1. c. p. 248 (1851). Biscoelius spinolce, Sauss. Vesp. i. p. 25 (1852). The male of this species is unknown. It is very rare; I have found only two specimens in the 25 years that I have collected m Chile. MONOBIA CYANIPENNIS. Odynerus cyanipennis, Guerin, Voy. Coq., Ins. p. 264, pi. ix. fig. 5, o* (1830). I once saw a specimen of this species caught in Peru and I am convinced that it does not occur in Chile to the south of Atacama. It probably occurs, however, in the northern provinces annexed from Peru. |
