Anterior antenne short, 5-jointed, thickly beset on 
the outer border with stout hairs, many of which are 
strongly pectinate or plumose; in the female (Plate 
XXXIV, fig. 3) the antenna tapers somewhat toward 
the extremity and terminates in two or three long, 
simple seta, the last joint being the longest and most 
slender ; in the male the organ is thicker, obtuse, and 
more distinctly arcuate, the whole outer margin beset 
with very strongly pectinate and plumose sete; the 
apex bears two stout falciftorm processes, and two or 
three similar (but setose) appendages occur amongst the 
hairs of the outer margin of the antenna. The posterior 
antenna (Plate XX XV, fig. 1) consists of two nearly 
equal branches, the main branch being composed of 
four joints, of which the second and fourth are the 
smallest; the secondary branch of six nearly equal 
joints which are short in the female (fig. 1) and longer 
in the male (fig. 2). The first pair of swimming feet 
is armed in the male (fig. 4) with somewhat longer
