6. On the Chilian Hymenoptera of the Family Odyneridce, 

 By Edwyn C. Reed, C.M.Z.S. 



[Eeceived July 26, 1893.] 



A fairly large number of Hjonenoptera of the fanulj Odyneridae 

 exist in Chile, but I have always found a diflSjculty in determiniug 

 them on account of the very careless way in which they have been 

 described by Spinola and De Saussure, in Gay's ' Historia Fisica y 

 Pohtica 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 pubhsh a Synopsis of the group, in the 

 ' Anales de la TJniversidad de Chile,' I have drawn up the following 

 list of the ChUian species. 



Gazelia, Spin, ia 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 ettmen-oides, Spin. 



This species is very local and far from common. Occurs in the 

 central provinces. 



Zethtjs dicomboda. 



EpijJona dicomboda, Spin, in Gay, vi. p. 250 (1851). 

 This species is not common. Occurs near Valparaiso and at the 

 Canquenes Baths. 



Labus sicheliajstts. 



Labus siclielianus, Sauss. Am. "Wasps (Smithsonian Misc. Coll. 

 xiv.), p. 56, pi. iv. fig. 20 (1875). 



This species does not exist in any collection in Chile. 



DlSCOELinS MEEUIiA. 



Biscoelius merula, Curtis, Trans. Linn. Soc. xvii. p. 825 (1834). 



Epipona cJiilensis, 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 

 foimd only two specimens in the 25 years that I have collected in 

 Chile. 



MONOBIA CTAJTEPENNIS. 



Odynerus cyanipennis, Guerin, Voy. Coq., Ins. p. 264, pi. is. fig. 5, 

 6 (1830). 



I once saw a specimen of this species caught in Peru, and I am 

 convinced that it does not occiu- in Chile to the south of Atacama. 

 It probably occurs, however, in the northern provinces annexed 

 from Peru.
