The above description applies only to the S • In the 
$ the abdomen is wholly testaceous-red ; in both sexes 
it is much narrower than the metasternum, but in the A 
it is exceedingly slender and linear in form. The hind 
tarsi in the $ are pale testaceous. In both sexes the 
head and thorax are black, and the elytra are one-third 
shorter than the abdomen. The long black hairs of the 
hind tibise form a brush all round the joint from the 
middle to the apex.
