Description of a New Specie;* of OUYNERUS from 

 North Mexico. 



BY P. CAMERON. 



Odynerns Packardi sp. dov. 



Black, the clypeus, a line, dilated above, on the lower side of the eye incisiou, 

 a spot, longer than wide and of equal width, over the antennae, two clearly sepa- 

 rated marks, narrowed on the outerside, on the base of the thorax, a narrow line 

 on the base of tegulse, a small squarish spot below them, a line on the base of 

 post-scutellum, a band on the upper part of the 1st abdominal segment and a 

 wider one, going all round, on the apex of the 2nd, pale yellow, legs black, the 

 apex of the femora and the tibiae broadly pale yellow, the tarsi of a darker 

 yellow. Wings hyaline, iridescent, the radial cellule fuscous violaceous, the 

 stigma and nervures black. ^. Length to end- of 2nd abdominal segment 

 6 mm. 



Clypeus as wide as long, sparsely punctured, the apex with a wide shallow in- 

 cision. Base of thorax transverse, the sides of the apex broadly rounded. Post- 

 scutellum broadly triangular, the apex rounded. The punctuation on the head 

 is strong, but not close; it is finely and closer on the sides of metanotum, the 

 centre is very sparsely punctured ; the base of metapleurse aciculated, the rest 

 distinctly, somewhat widely punctured. Base of 1st abdominal segment smooth, 

 the top with an indistinct ridge, the rest is strongly punctured, the apex is 

 slightly raised ; the segment is cup-shaped, narrower than the 2nd. The 2nd 

 segment is slightly wider than long; its apex is more strongly punctured than 

 the rest and is strongly reflexed ; at the base it is rounded, not transverse. There 

 are no furrows on the mesonotum. The punctuation is coarser and closer on 

 the head than on the thorax ; the pubescence is short, sparse. 



Belongs to the section Stenancistrocerus, 3, h, of Saussure's Syn. 

 of Araer. Wasps, p. 209.
