scutellum elevated, metathorax rounded at the sides and not 

 higher at any part than the base of the postscutellum. Pronotum, 

 except its posterior angles, tegulae, a spot under root of wing, two 

 spots on the scutellum, two on the postscutellum, two on either 

 side of metathorax, extremity of the first three abdominal segments, 

 sulphur-yellow. The 2ud and 3rd abdominal rings are continued 

 beneath, but interrupted in the middle. 



Terminal joint of antennae long, blunt, curved, the apex being 

 thus rather spiral than hooked. 



Length 13 milHm., wing 10 millim. 



Caught at the Canquenes Baths. 



Odyneeus testitus. 



Odynerus vestitus, Sauss. Vesp. iii. p. 252 (1854). 



I have never seen this species. 



OnXITEEirS HtTMEEALIS. 



Odynerus Tiumeralis, HaUday, Trans Linn. Soc. xvii. p. 324 

 (1837). 



Odynerus cMlen^s, St.-Farg. Hym. ii. p. 643 (1841) ; Gray, 1. c. 

 p. 235 (1851). 



The largest Chilian species. Very common.

Odynerus villosus, Sauss. in' Gay, p. 563 (1852). 

 Described from a female specimen. Appears to be Uke 0. vespi- 

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



Odtneeus obsctteipexnis. 



Odynerus obscuripennis, Spin. 1. c. p. 259 (1851). 



Odynerus coquimbensis, Sauss. in Gray, p. 561 (1852). 



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

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

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

 might have been a var. of 0. Tiumeralis. 



Odtnbeus antuco. 



Odynerus antuco, Sauss. in Gay, vi. p. 562 (1851). 



Odynerus anUicensis, Sauss. Vesp. iii. p. 228 (1854). 



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. 



Odtnbeus chiliotus. 



Od/ynerus chiliotus, Sauss. in Gay, vi. p. 566 (1852). 



Described from a single male specimen. Unknown in Chilian 

 collections.
