Fig. 1. The female from the side. 2. The second pair of perieopoda. 3. The third pair. 4. The urus. 



The hody is soraewhat broader than in the male, the pera;on being a little broader 

 than the head, and nearly twice as broad as the pleon. The head and perajon together 

 are considerably longer than the pleon and urus together. The body is distinctly 

 carinated dorsally. 



The liead is quite as long as deep, and somewhat broader than long; it is not fully 

 as long as the tirst three personal segments together. The young female has the head 

 comparatively larger, and considerably deeper, than the pera-on, but still it is shorter than 

 the first three perseonal segments together. 



The fi,rst pan of antennce (Pl. XIII, tig. 1 — 4) in the adult female are quite as 

 long as the head, and consist of a three-jointed peduncle and a single flagellar joint. 

 The iirst joint of the peduncle is longer than the two foUowing together. The single 

 flagellar joint is nearly four times as long as the whole peduncle; it is evenly curved, and 

 coaTsely serrated along the under margin; the inner side is densely set with long hairs 

 (Pl. XIII, fig. 1). In the young female the first pair of antennas are much shorter than 

 the head, and the single flagellar joint is short, irregularh' conical, and scarcely longer 

 than the peduncle (Pl. XIII, fig. 4).
