EUMENES. 109 



scutel not flat nor entire; the petiole shorter, not so distinctly 

 sulcate. — Very distinct from filiformis by the same characters 

 and by its nearly impunctate abdomen. 



Bab. Brazil. Pernambuco. This insect was bred in a ne&t 

 of Chalicodoma; if as a parasite I could not ascertain. 



53. E. ifi I if or ill a s Sausp. — Niger, antennis subtus et abd. apice, fer-

 flavo-bimaculato ; thornce brevi, dense punetato, postscuttdlo et meta-

E. filiformis Sadss. Et. Vesp. Ill, 146, 34, $. 



Total length, 17 mm. ; wing, 13 mm. 



Antennas long and slender. Thorax shorter than that of E. 

 canalicidatus, almost globular, squarely cut before, densely 

 punctured ; the post-scutellum and the metathorax cribrose with 

 punctures, stronger and less serrate, while in the species cited 

 the thorax is everywhere velvety and finely punctured. The petiole 

 is a little longer than the thorax, very narrow, a little enlarged 

 from before backward, arcuate, flattened, irregularly punctured. 

 Its groove but slightly distinct. The second segment compressed, 

 very densely shagreened, appearing rugose above; the punctures 

 much more dense, but not as large as on the metathorax ; the 

 first posterior border of this segment slightly turned up and pre- 

 ceded by a transverse depression in the middle; the 2d border 

 narrow, profoundly sunken. 



Var. The ornaments of the thorax and of the abdomen are 

 generally of a sombre ferruginous rather than yellow, indistinct; 

 the border of the 2d abdominal segment is sometimes yellow, 

 sometimes ferruginous. 



Black, fulvo-velutinous; flagellum of the antennae beneath, edge 

 of wing scales, knees, and margin of the abdominal segments 

 ferruginous; posterior margin of prothorax and an interrupted 

 fascia at the extremity of the petiole, yellow. Wings washed 

 with brown in the basilar half, subhyaline at the extremity. 



9. Clvpeus black, smooth, lengthened, narrow above; its 

 greatest width is in its lower third, carrying two little bosses in 

 the middle (of its height), the terminal border notched at a very
