 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 setaa, 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 seta3 ; the 

 apex bears two stout falciform processes, and two or 

 three similar (but setose) appendages occur amongst the 

 hairs of the outer margin of the antenna. The posterior 

 antenna (Plate XXXV, 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
