are one and a half times as long as the palm, bul in Bate's figure 4 the fingers of 

 the I*' and 3''^ pairs appear not longer than the palm. The legs of the i^' pair extend as far 

 forward as those of the 5"', almost to the middle of the antennal scales, whereas those of the 

 3"^'' pair reach with their fingers beyond the tip of the latter. 



Sternum armed with a flattened spine arising between the bases of the legs of the 

 4''' pair, the two spines between the legs of the 2"'^ and 3'''^ pairs are also distinct. 



Remarks. It is doubtful whether de Haan's Sic. cristata froni Japan is identical with 

 ihis species or not, I will, however, observe that de Haan's description is not in accordance 

 with his figure. He describes the pleura of the i^' abdominal somite as unispinose, like in Sic. 

 lancifer., but in the figure one observes two spines ; the 2"*^ and the 3'<^ pleura are described 

 as bispinose, but in the figure the 3'<i is armed with three spines. Pearson (1. c.) regards this 

 species as distinct from Sic. lancifci\ but his words "the abdomen dift'ers only from that of Sic. 

 lancifer in not having pleural spines on each segment" are not in accordance with de Haan's 

 description. The male from Japan, described by Dr. Ortmann, seems to be a true Sic. lancifer, 

 perhaps therefore the two species are identical.
