AMERICAN HYMENOPTERA. 341 



notum furrowed, sericeous, dorsulum striato-punctate. Scntelluni sparsely punc- 

 tate. Tubercles and postscutelluni laterally witli a tuft of long yellowisL pubes- 

 cence. Metathorax sculptured, coarser than in %, smooth area well developed, 

 covered with erect silvery pubescence. Mesopleurse and underside of femora 

 sericeous. Space between first and second transverse cubitals on radial nervure 

 variable, small, second recurrent nervure almost interstitial with the second 

 transverse cubitus. Petiole distinctly trisulcate, with sparse erect hairs. Abdo- 

 men shining, first segment almost base, the rest silvery sericeous. Black. 

 Underside of joints one, two, three and four of the flagellum ferruginous below, 

 above and the rest of the joints entirely seal-brown. Tegulse and base of the 

 wings testaceous, spurs and tarsi whitish. 



Related to mellipes Say S (as determined by Mr. Fox), from 

 which it differs in having joints of flagellum simple, coarser in sculp- 

 ture of metathorax and larger size.

ITIiinesa ferrtiginea n. sp. 



Head coarsely punctured, dorsulum coufluently punctured, metathorax coarsely 

 reticulated, ferruginous, as is the petiole and greater part of first two abdominal 

 segments. 



"J, . — Length 12 mm. Head closely and strongly punctate, punctures on ver- 

 tex coarser and sparser, impressions behind posterior ocelli marked and shining. 

 Clypeus tridentate, its surface covered with rather lung silvery tinged with yel- 

 low, pubescence, which extends up on the face somewhat above insertion of an- 

 tennae, front and vertex, with sparse, long, yellowish pubescence, cheeks silvery 

 sericeous. Antennae somewhat longer than head and thorax, slightly flattened 

 and dilated beyond the middle, joints four to nine of the antennai curved out- 

 wardly, anteriorly impressed above just within the margin. Prothorax with a 

 transverse channel, angled anteriorly and covered with golden apressed pubes- 

 cence. Dorsulum coarsely striate punctate, with an impressed line starting at 

 the middle of each side and runs to posterior margin, scutellum strongly punc- 

 tured. Metathorax reticulate, impressed at base medially, the pits large and 

 shallow, mesopleurae confluently punctured, covered with short silvery pubes- 

 cence, tegulae and postscutellum with long, gold -tinted erect pubescence, to each 

 side of metathoracic impression there is a patch of erect silvery or gold-tinted 

 pubescence. Wings strongly tinged with yellowish brown, first recurrent nerv- 

 ure received by the second submarginal cell just before the middle, the second 

 recurrent nervure received a little less than one-fourth the length of the cell 

 before the second transverse cubitus, tegulae and base of wings testaceous, stigma 

 a tawny olive, nervures dark. Petiole longer than posterior femor, rounded 

 above, smooth and shining, slightly flattened at base, first abdominal segment 

 smooth and comparatively bare, segments two, three, four sparsely sericeous on 

 apical half, the rest of the segments apparently entirely sericeous. 



Color: Joints one, two, three, four and part of five of flagellum dull ferrugin- 

 ous, scape shining ferruginous, the rest of the joints seal-brown. Legs shining,
