Described from a single S in the Indian Museum. Kufri, 

 Simla Hills, 8000 ft., 11. v. 1909 {Annandale). There is about 

 this species some general resemblance to /S. albostriatus, Fin., but 

 the thorax has no pale stripes and the bands on the 3rd and 4th 

 abdominal segments are se])arated into spots. It is also obviously 

 allied to, though distinct from, S. op'nnius, Walk., the abdominal 

 spots being smaller and practically linear, instt'ad of distinctly 

 sub-lunate and considerably larger. It is also a smaller species.
