area rugose. Petiole with the lateral teeth between the spiracles 

 and the base well developed ; spiracles prominent, obscurely striate 

 between the spiracles, the remainder of the segment smooth and 

 convex ; before the spiracles the raised area is distinct. Hind 

 cox?e closely and rather finely punctured, femora very iinely 

 punctured. Second abscissa of the radius about equal to the 

 second transverse cubital nervure, the latter fully twice as long- 

 as the distance between it and the recuri-ent nervure.

5 . Differs from subceqv.ale in the strongly bidentate (text- 

 fig. 6 c) mandibles, the upper tooth much shorter than the lower, 

 in the much more strongly punctured face, in the generally 

 stronger puncturation, and in the sculpture of the hind coxa? and 

 femora, which are shining, with large punctures in occidentale, 

 whereas in suhmqucde the hind femora are subopaque and very 

 closely covered with minute punctures.
