Show 688 MR. E. 0. REED ON CHILIAN [Nov. 7, 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 2nd 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 millim., wing 10 millim. Caught at the Canquenes Baths. ODYNERUS YESTITUS. Odynerus vestitus, Sauss. Vesp. iii. p. 252 (1854). I have never seen this species. ODYNERUS HUMERALIS. Odynerus humeralis, Haliday, Trans Linn. Soc. xvii. p. 324 (1837). Odynerus chilensis, St.-Farg. Hym. ii. p. 643 (1841); Gay, 1. p. 235 (1851). The largest Chilian species. Very common. ODYNERUS YILLOSUS. Odynerus villosus, Sauss. in" Gay, p. 563 (1852). Described from a female specimen. Appears to be like 0. vespi-formis. It does not exist in any collection in Chile. ODYNERUS OBSCURIPENNIS. Odynerus obscuripennis, Spin. 1. c. p. 259 (1851). Odynerus coquimbensis, Sauss. in Gay, p. 561 (1852). I unite these two descriptions on tbe authority of De Saussure. Gay'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. humeralis. ODYNERUS ANTUCO. Odynerus antuco, Sauss. in Gay, vi. p. 562 (1851). Odynerus antucensis, 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. ODYNERUS CHILIOTUS. Odynerus chiliotus, Sauss. in Gay, vi. p. 566 (1852). Described from a single male specimen. Unknown in Chilian collections. |
