smooth; 2"'^' to 5"' terga slightly carinate, the 2'"' higher 



than the rest crcnatus (W'hitelegge) 



(Til W'hitelegge, in: Mem. Australian Museum, Sydney, IV, 1900, p. 194, 

 fig. 14). 



C:. Abdominal terga with more or less distinct arborescent markings 



or squamiform sculpture. 



d^ Proximal antennal squame dorsally traversed by two oblique 



ridges, both edges serrated. Some sc[uamiforin sculpture 



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



the pleura r//(5^«i- (A Icock and Anderson) 



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

 1S94, pt. 2, p. 165). 



d.^ Pro.xiinal antennal squame dorsally traversed only by one - 

 ridge '). 

 e^ Squamiform sculpture inconspicuous on first abdominal 

 tergum and on the anterior half of second and third; 

 proximal antennal sc|uame with one tooth on the outer 



and three on the inner margin vitiensis (Dana) 



<:., Squamiform sculpture distinctly developed on all the 

 abdominal terga. 

 /"j Propodi of 2°'i and 3"^ legs distinctly broadened, com- 

 pressed and nearly of the same form, ])ropodi of 4''^ 

 and 5''^ legs subcylindrical, distinctly longer than those 

 of 2'"' and 3''', and of a cpiite different form. Dactyli 

 of 2""^ legs nearly of the same form and length as 

 tho.se of the i'''. 

 g^ Proximal (outer) antennal scjuame with both edges 

 serrated by several teeth : anterior, unsculptured 

 jjart of 2"^' abdominal tergum smooth, not grooved 



transversely , . . . orientalis (Sp. Bate) 



,^2 Proximal (outer) antennal squame with the outer edge 

 armed with two teeth, the inner with one; anterior 

 unsculptured part of 2'"^ abdominal tergum with two 



transverse parallel grooves /laatiii Berthold 



y^ Propodi of 2"'' and 3"' legs, though slightly compressed, 

 not broadened, those of 2"'' legs distinctly tapering, 

 styliform ; propodi of 4''' and 5''' legs nearly of the 

 same form and the; same length as those of 3'''', 

 though decreasing in width ; dactyli of 2""^ legs longer 

 and slenderer than those of 1^'. 



i) In Scy//. Marliiisii one observes a short second ridge on U\e outer half of the upper surface of the proximal >quaine near 

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