 and moderately separated, their summits deeply concaved and margins 

 rather sharply elevated ; shelf-like projection moderately wide and

 the fifth somewhat longer that the fourth. 



Thorax. — Anterior part of dorsum covered with yellow pile back to 

 the tegulae, this color usually extending down onto the mesopleura 

 considerably below the bases of the wings and often even covering as 

 much as the upper halves of the mesopleura ; the remainder of the 

 thorax black. 



Abdom.en. — Dorsum : segment one black ; segment two yellow ; seg- 

 ment three black ; segment four with the basal portion black and the 

 apical portion (sometimes only the apical margin and sometimes even 

 more than the apical half) clothed with white or whitish pile ; segment 

 five entirely covered with white pile; segment six mostly dark, but 

 usually with more or less white or whitish pile on the sides. Venter 

 mostly black, but usually with more or less whitish pile on the sides 

 of the apical margins of the apical segments.
