OBTNEErS VESTITirS.

 I have never seen this species. 



ODT>'EErS HUMEEALIS. 



Ochfnerus Immeralis, Halidav, Trans Linn. Soc. xvii. p. 32-1 

 (1837). 



Odiinerus chilensis, St.-Farg. Hym. ii. p. 643 (1841) ; Gray, 1. c. 

 p. 235 (1851). 



The largest Chilian species. Very common. 



ODYNEErS TILLOSUS. 



Odynenis villosus, Sauss. in Gay, p. 563 (1852). 

 Described from a female specimen. Appears to be like 0. vespi' 

 fonnis. It does not exist in any collection in Chile.

Odynencs ohscuripennis. Spin. 1. c. p. 259 (1851). 



Odi/nenis coquimhensis, Sauss. in Gay, p. 561 (1852). 



I unite these two descriptions on the authority of De Saussure. 

 Gay's description was drawn up from an incomplete specimen. 

 Probably De Saussiu'e's was taken from the same fragment, which 

 might have been a var. of 0. humeralis.

Said to be the only Chilian species with a single abdominal belt. 



It is a pity it has not a single name also. I do not know the 



species. 



Odtkeeus chiliotus. 



Odynerus cMliotus, Sauss. in Gay, vi. p. 566 (18.52). 

 Described from a single male specimen. Unknown in Chilian
