t/ x Proximal antennal squame dorsally traversed by two oblique 



ridges, both edges serrated. Some squamiform sculpture 



on the abdominal terga, especially on the 6 ,h , and on 



the pleura rubens (Alcock and Anderson) 



(A. Alcock and A. R. S. Anderson, Journal Asiatic Soc. Bengal, LXIII, 

 1894, pt. 2, p. 165).

tergum and on the anterior half of second and third; 



proximal antennal squame with one tooth on the outer 



and three on the inner margin vitiensis (Dana) 



e, Squamiform sculpture distinctly developed on all the 



abdominal terga. 



f\ Propodi of 2 ud and 3 vd legs distinctly broadened, com-

1) In Scyll. Martensii one observes a short second ridge on the outer half of the upper surface of the proximal squame near 

 the base, but this species differs from Scyll. rubens by the strong development of squamiform sculpture on the whole abdomen.
