by a slightly less distance than they are from the eyes. Apex of clypeus 
broadly rounded. Third antennal joint about one quarter longer than the 
4th. Metanotum transversely striated, more weakly at the base than 
elsewhere. Apex of pronotum bluntly, roundly angled in the middle. 
Long spur of hind tibiae slightly more than one-third of the length of 
metatarsus and as long as the 2nd joint. <$. 
Length 8 mm. 
Dehra Dun, July. 
Metanotum gradually roundly sloped from the base to the apex, 
the metapleurae opaque, pronotum large, rounded in front probably in fresh 
examples the head and thorax are densely covered with white pubescence, 
in the specimen examined it is dense on the mesopleurae and coxae. 
Comes, in Bingham's work, nearest to 8. electus Cam.

Two damaged specimens taken at Rundali, Dehra Dun, in June are 
probably referable to this species of which S. lineatipes Cam. is perhaps 
a variety. The tibiae in the Dehra Dun examples are only lined with 
black in front, not entirely black as in the type. 8. tibiale is a variable 
species as regards the markings, a less rare form has 2 yellow marks in 
the centre of the metanotum. Its nearest ally known to me is the New 
Guinea species S. Bruinjnii, Maid. S. lorentzi Cam. being also related 
to it. 8. Bruinjnii may be known from it by the post-petiole, and all 
the following abdominal segments being ferruginous, with the base of the 
•3rd to 6th lined with black, the apex of its clypeus, too, is broadly rounded, 
not bilobate.

narrow furrow having a keel down its centre, it is slightly shorter than
