$ . — Length about 13*5 mm. 



Rather robust, black, with clear ferruginous femora, tibiae, 

 and tarsi; head ordinary, with dense pale oehreous hair, 

 except on clypeus, where the hair is long and so thin that 

 the clypeus seen from in front appears nude; clypeus rugose 

 but shining, with a very strong median keel on upper three- 

 fourths, lower margin straight except for a slight crenulation; 

 mandibles black, the cutting-edge long and very oblique, 

 with only two teeth, the apical one long ; thorax densely 

 covered with pale ochreous hair, becoming fulvous on 

 scutellurn ; mesothorax strongly punctured, the punctures 

 mainly in transverse rows; tegulse red. Wings dusky 

 reddish ; abdomen broad and parallel-sided, the hind margins 

 of the segments with entire bands of bright ferruginous 

 hair, the rest of the dorsal surface covered with short thin 

 red hair, except the first segment, which has longer fulvous 

 hair; ventral scopa whitish basally, grading into copper-red 

 apically.
