base. The apex of the metapleurae strongly reticulated ; the rest impunctate, except a 

 punctured wedge-shaped part in the middle, which does not extend to the top. The 

 legs (especially the tibiae and tarsi) densely covered with long white hair ; the femora 

 with scattered punctures ; the tibial spines are fulvous, the calcaria white. The basal 

 segment of the abdomen entirely ferruginous, except the extreme base and the teeth, 

 which are stout ; it has scattered punctures and is covered with long white hairs. The 

 second segment with fine scattered punctures ; the base slightly depressed and more 

 closely and strongly punctured, and fringed with rufous hair. The other segments 

 finely punctured and fringed with rufous hair. The pygidium punctured, rather densely 

 covered with long fulvous hair ; the apex is oblique ; down the centre of it there is an 

 area, which is open at the apex and rounded at the base, the keel forming it curving 

 round at the bottom and going along the edges. The first ventral segment punctured, 

 at the base projecting in the middle in a blunt tooth, at the apex triangular, oblique ; 

 the second segment with some rather large punctures ; the other segments finely punc- 

 tured. The hypopygium has a moderately stout keel, raised at the base into a blunt 

 tooth ; inside of these towards the apex are two flat, brown, curved teeth; its apex is 

 transverse. The wings are lighter coloured at the base ; the radial cellule does not 

 extend beyond the third cubital, is moderately wide, and longer than the first cubital ; 

 the basal abscissa of the radius is straight, oblique, and shorter than the apical, which 

 is elbowed near the top ; the second cubital cellule at the top is about the length of the 

 space bounded by the first transverse cubital and the first recurrent nervures ; the third 

 cubital cellule is narrower at the top than at the bottom; the first transverse cubital 

 nervure is broadly, the second sharply curved, the third sharply angled above the middle ; 

 the transverse median nervure is recurved in front of the basal.

Head not much narrower than the thorax, apparently coarsely punctured, the sculp- 

 ture hidden by a dense glistening white pubescence, except round the ocelli ; the clypeus 

 shining, impunctate, the apex broadly rounded; the mandibles dull ferruginous before 

 the apex. The eyes are large, the head very slightly developed and narrowed behind 

 them. The prothorax with scattered punctures ; the base without much pubescence, 

 the apex, however, having a dense broad band of whitish pubescence. The mesonotum 

 with large, deep, distinctly separated punctures ; there is an indistinct keel down the 

 middle, and on either side of this a furrow. The scutellum is moderately convex, and 

 it bears large punctures and a dense covering of long glistening white hair. The tegulse 

 project behind ; the basal half shining, glabrous, the apical half with a dense covering of 

 griseous hair, except on the extreme outer edge. The median segment reticulated, and
