Odijn. spectabilis Sauss. Revue de Zool. XXII, 1870, 60, lb*, 9 . 



Total length, 9 mm. ; wiugs, 7 mm. 



Slender. Head and thorax rather coarsely and densely sha- 

 greened. Thorax square. Post-scutel crenulate, metathorax 

 rather flattened behind, forming on each side a strong, acute 

 angle looking outward, which makes the posterior part of thorax 

 square, the middle of the hinder face a little excavated, rather 

 rugose, but the cavity not margined ; the rest quite rugosely 

 punctured, reticulate. Abdomen nearly conical, smooth, silky; 

 the 2d segment finely punctured, but its margin and those follow- 

 ing strongly punctured. 



Black. Antennae black-ferruginous, with the first three joints 

 ferruginous. Mandibles rufous. Clypeus, a frontal triangle, an 

 ocular and post-ocular large macula, prothorax anteriorly, spot 

 under the wing, tegulse, scutel, post-scutel, angles of mesothorax 

 and margin of all the abdominal segments, yellow, rather orange ; 

 the yellow margin of 1st segment fused with two large, lateral 

 angular yellow maculae ; anus, feet, even the coxae, orange-yellow. 

 Wings washed with ferruginous; the radial cell cloudy. 



9 . Clypeus wide, rather lozenge-shaped, with its apex truncate, 

 biangulate. 



Var. The last abdominal segments rufous. 



Bess. a. diff. — Recalls the 0. bacuensis by its appearance, but 

 is very distinct by its broad clypeus 9, its crenulate post-scutel. 

 angulate metathorax, and conical abdomen, etc. From 0. cubemsis 

 and allies it differs by its more slender form and metathorax with- 

 out acute superior edges. — From 0. formosus, by a larger size 

 and less slender form. If it was not as small again, it would 

 agree perfectly with the description of 0. apicalis Cress. It 

 may be a small variety of this?
