1893.] HTilEN'OPTEEA OF THE FAMILT ODTi^TERID-i;. 689 



Odtnerits MATPI>'US, 



Odynerus maypinus, Sauss. in Gay, p. 564 (1852). 

 Also described from a single male specimen. May possibly be 

 the male of 0. antuco. 



Odti^eeus buficollis. 



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



Described from a single female specimen. 



Odtn'eetjs tespifoemis. 



Odynerus vespiformis, Haliday, Trans. Linn. Soc. xvii. p. 323 

 (1837). 



Odyneinis Jiirsutus, Spin. 1. c. p. 257 (1851). 



A very common and distinct species. 



Odtnerfs gati. 



Odynerus gayi, Spin. 1. c. p. 260 (1851). 



A northern species ; commoner in Copiapo than to the south. 



Odtnteus sotoi, sp. nov. 



Allied to 0. gayi, but larger, stouter, and with the last joint of 

 antennae in male reciu-ved, forming a hook. 



$ . Head finely and closely, thorax thickly and roughly, punc- 

 tured. Abdomen finely and distantly punctured. Head and 

 thorax dull, abdomen shining, black. Antennae, legs, and clypeus 

 rust-red. A spot above the insertion of the antennae, a line behind 

 the eyes, anterior | of pronotum, tegulge, spot at root of wings, two 

 squarish spots on scutellum, a line on postscutellum, posterior 

 margins of metathorax, extremity of the first three abdominal 

 segments, reddish yellow. Coxae black, intermediate pair reddish 

 anteriorly. 



Clypeus hexagonal, very wide above ; legs stout ; apex of tibiae 

 and tarsi with short spiny hairs. 



Length 15millim., wing 11 millim. 



I received specimens of this species, from Copiapo, in alcohol, 

 which may account for the reddish tint of its markings ; these are 

 probably yellow during life. I have only one male, not in good 

 condition, so that I cannot describe it at length. 



Odtneeus aeaucanus. 



Odynerus araucanus, Sauss. Reise Novara, Hym. p. 14, pi. 1. 

 fig. 8 (1868). 



I do not know this species. 



Alastoe angulicollis. 



Odynerus angulicollis, Spin. 1, c. p. 261 (1851). 



Very rare. I have one male specimen.
