The palpi have the second joint large and broad, tapering 

 to a point. In both sexes the ])ostcrit)r parts of the thorax 

 and the scutellum are adorned with a fringe of yellowish

 in the female the yellow hairs are chiefly on the middle of 

 the posterior borders of the segments as triangular spots, and 

 on the lateral posterior margin of second segment there is a 

 well-marked tuft of white hairs, overlooked by Walker.
