 pubescence and an apical fringe of silvery hairs; second tergite with 

 shallow, elongate punctures, sparse at the sides, more or less con- 

 fluent on the disk ; basal third and subapical margin of second tergite

 sparse, silvery pubescence, remainder of disk with sparse, appressed, 

 golden pubescence; tergites 3-5 with scattered, indistinct punctures, 

 clothed with sparse, silvery pubescence; pygidium strongly convex, 

 especially at the base, distinctly longitudinally striate, the striae not 

 reaching to the tip, the subapical portion of the pygidium very
