Very like the preceding, but rather smaller, and at 

 once distinguishable by the long face, which is longer 

 than wide across the eyes, and also by the white colour 

 in the <? being carried up high above the antennse on 

 each side, and the spots in the ? being linear and border- 

 ing the eyes, extending from above the antennae, not 

 quite to the base of the clypeus ; the vertex of the head 

 also is longer, and the puncturation of the abdomen in 

 the ? much larger and deeper, its surface dull ; the 

 rugosities of the metathorax much coarser and shining. 

 Wings somewhat dusky. <? genitalia unusually large 

 for the size of the species. Stipites apparently with a 

 transverse impressed line about the middle ; their apex 

 subtruncate. Sagittae very long, as long as the stipites.
