blackish towards tip, emargination of segments black ; belly con- 

 colorous. Genital organs conspicuous and large, consisting of 

 a rather large upper part, with two small terminal lamellae bearing 

 long hairs ; a pair of large fleshy claspers and a pubescent ventral 

 plate, bilobed at tip. Legs (middle pair wanting) : coxae and 

 trochanters reddish yellow, with some black hairs on anterior 

 pairs, and yellow hairs on hind pair. Femora (fore pair distinctly 

 but not greatly, thickened towards the tip) yellow; apical 

 fourth black, and with a black ring in the middle which is very 

 wide on the fore pair and moderately wide on the hind pair. 

 Tibiae blackish brown, pale at extreme base. Pore tarsi blackish 

 brown, hind pair yellowish white, claws black, apart from the 

 minute pubescence of the whole legs. The only stiff hairs are a 

 row of weak ones on the outside of the hind tibiae, and on the 

 lower side of the hind tarsi ; a few stiffer hairs on fore tibiae. 

 Wings grey, unmarked ; venation as in S. ceylonica, but the veins

 arranged in a curve, two long ones on the scutellum and a large 

 one on each shoulder ; also a strong one a little below each wing ; 

 pleurae with some minute stiff hairs. Abdomen with rather longer 

 soft pubescence ; posterior margins of abdominal segments with

 claspers a smaller fleshy projecting pubescent organ ; below all, an 

 onion-shaped ventral plate, which, as well as the whole genitalia,
