flagcllum covered with a pale down ; the apical joints 

 more or less brownish beneath ; the third and fourth joints 

 are almost equal in length ; the front and vertex sparsely 

 covered with long black, the antennal region and the 

 clypeus with long white hair. The front and vertex are 

 coarsely rugosely punctured. The upper part of the 

 clypeus is roundly convex, slightly and gradually widened 

 towards the apex ; the apex is depressed, distinctly mar- 

 gined laterally, and marked before the apex with a distinct 

 transverse keel, which projects roundly backwards in the 

 middle, there being also a raised part at the apex of this 

 projection. Mandibles black, piceous before the apex ; the 

 hairs are long and pale fulvous. Frothorax rugosely punc- 

 tured, except at the base and apex of the pleurre ; the meso- 

 pleurae rugosely punctured, except in the middle at the base; 

 behind, the punctures run into reticulations ; the metapleurae 

 coarsely reticulated on the apical half; the middle and 

 the upper part of the basal portion smooth ; the lower 

 part of the base with long, shallow, irregular punctures. 

 Legs thickly covered with long white hair ; the calcaria 

 and spines white ; the claws rufous ; the base of the 

 incision on the anterior tarsi is also rufous. Wings 

 uniformly brownish, with a slight, but distinct, violaceous 

 tinge ; the nervures are testaceous ; the second and third 

 cellules at the top are equal in length ; below, the second 

 is about one-third longer than the third ; the second 

 cellule receives the recurrent nervure in the middle ; the 

 second recurrent is received shortly beyond the middle. 

 The petiole and the second abdominal segment, except 

 at the apex, are ferruginous, closely punctured and sparsely 

 covered with long white hair ; the petiole is short, scarcely 

 one-half the length of the second segment, broad, 

 narrowed at the base ; the second segment is obliquely 

 raised towards the middle ; at the base the slope is longer
