towards the marginal; the legs black, entirely covered with a 
slate-coloured pubescence; the anterior tarsi ciliated, and the 
intermediate and posterior tibie with a double row of slight 
spines. 
The abdomen black, pubescent, slightly shining, with the 
margin of the three anterior segments having a fascia formed 
by a short dense slate-coloured down: the pubescence varies, it 
sometimes covers the whole of the segments except their base, 
and sometimes it is very slight, forming merely an interrupted 
band on the three first. 
The ¢ differs in having the face covered with more of the 
silvery down, the tarsi less strongly ciliated, and the legs less 
spinose, and the slate-coloured pubescence covering the entire 
insect, excepting the antennez and a narrow line at the base of 
the segments of the abdomen, which are consequently black and 
shining ; the sixth ventral segment is emarginate, and the seventh 
longitudinally carinated.
