Types: Rcturnccl in Indian Mnseum. One £ and one 5, paratypes, retained. 



Body and cercopods of Imth sexes relatively slender. First antennae of both sexes 

 are relatively longer, and appear irregularly segmented. The 2nd antennae of the 5

row of spines of the main branch of the finger is more regular than in S. s. simplex and does 

 not run over onto the inner side of the branch, and the spines are much more numerous. 

 There is also a row of short, conical spines along the outer side of the main branch i>f the 

 finger. The sickle-shaped branch of the finger is armed along the proximal 4/5 of its con- 

 cave edge with short close-set spines which become somewhat papilliform distally. The 

 thumb is a little longer than in 5". j. simplex, its length from thumb-notch to tip being aliout 

 4/5 of the length of the main branch of the finger as measured from tlie dorsal spine. The 

 dorsal process of the thumb is lacking, and the dorsal groove of the thumb is scarcely indi- 

 cated. The finger-notch is obsolescent. The 2nd antennae of the 9 2 are rather narrower 

 than in the typical form. Length oi $ £ alx)ut 20 mm., of 9 9 about 18. In other respects 

 this subspecies is very similar to .S". .?. simplex.
