Stenomutilla bischoffi, new species. 



Maie. — Black; calcaria brown. With erect white and reddish brown 

 hairs; the latter prédominant on the dorsum, upper parts of the head, 

 and second tergite; the white ones absent on the fourth, fifth, sixth, 

 and seventh abdominal segments. Bands of decumbent, but not 

 matted white setae on the apex of first, second, and third tergites. 

 Wings infuscated, a little paler at base. 



Length : 12,5 mm. 



Head seen from above transverse; the margins behind the eyes 

 but slightly convergent; the hind angles moderately rounded; the 

 posterior margin slightly convex, but medially produced backward 

 into a short neck. Head very coarsely, densely, delicately punctate. 

 Ocelli in an equilateral triangle, the base of which is placed upon 

 the postocular line. Front punctured like the vertex. Antennal grooves 

 not margined above. Superior portion of the clypeus forming a loz- 

 enge-shaped élévation the surface of which is flat, coarsely punctate 

 and covered with long setae which obscure the structure of the cly- 

 peus; one angle of the lozenge is produced into a sharp keelbetween 

 the antennae; the inferior angle forms a corresponding carina project- 

 ing toward, but sloping abruptly down to, the anterior margin of the 

 clypeus. Mandibles bent, short; the apices acute; the inner margin 

 with two small teeth, without a broad lobe; outer margin simple. 

 Second segment of flagellum much shorter than the third, a little 

 longer than the first. Eyes broadly oval, with only a suggestion of an 

 emargination within. Dorsum punctured like the vertex, uniformly 

 convex; anterior margin of pronotum concave; the humerai angles 

 rather prominent, but rounded. Tegulje small, but roughly sculptured. 

 Parapsidal furrows but weakly indicated and only posteriorly. Scu- 

 tellum flat, but divided posteriorly by a médian dépression into two 

 lobes. The middle portion of the propodeum sloping almost directly 

 from the postscutellum to the pétiole, so that it présents no distinct 

 dorsal surface; coarsely reticulate; laterally with a distinct dorsal 

 surface which is also coarsely reticulate; postero-lateral angles some- 

 what prominent, but not acute; latéral surface coarsely reticulate. 

 Mesopleurae with a transverse dépression below the tegulas; with a
