being very finely and minutely granulose-punctate; the 
sides are margined, and on the dise of each are very faint 
traces of two. longitudinal striz; the anterior tibiz are 
broad, slightly curved and flattened, with a longitudinal 
impression on the upper side ; the terminal calcar is 
elongated, narrow and rounded at the tip; the hind tibiz 
are rather curved, with the outer apical angle considerably

tures and clothed with pitchy-brown, velvet-like plush, less 
distinct on the terminal segment; the prosternum between
