 middle is a large, black mark, extending from near the base to the 

 apex ; its apex almost transverse, but slightly incised in the middle ; 

 beyond its middle the mark becomes narrowed gradually but dis- 

 tinctly, then becomes dilated into a triangle, which at its apex, is 

 slightly wider than the widest part of the basal portion ; the 

 lateral marks are slightly wider than the central ; they are as long 

 as the basal part of the central mark ; slightly dilated in the 

 middle on the outer side, and oblique at the apex ; median seg- 

 ment [metathorax] smooth ; the central basal area almost square ; 

 from its centre and apex two stout keels run to the sides where 

 they unite with a longitudinal keel, thus forming two lateral areae 

 on each side ; pleura) very smooth and shining ; on the meta-

 tlie sides of the petiole extends to the middle — to the base of the 

 black dot ; the transverse, curved furrow on the second segment 

 is longitudinally striated ; those on the other segments are also 

 striated, but not so distinctly ; the black marks on the petiole 

 small, on the second segment slightly larger and dilated in the 

 middle at the apex ; on the third and fourth larger, on the fiftli 

 and sixth still larger, broader, being distinctly broader than they 

 are long ; on the sixth [sic] small and may be absent ; the sixth 

 has a wide, transverse band, incised in the middle at the apex ; the 

 oblique furrows on the last segment narrow, deep, and distinct ;
