except a yellow median spot, spots on the pleurse above the 

 coxse, the margins of the scutellum and postscutelium, the 

 mesosternum, a triangular spot at the apex of the median 

 segment, and the base and apex of each of the abdominal 

 segments rather broadly above, more narrowly beneath, dull 

 ferruginous. Wings hyaline ; nervures fuscous, testaceous 

 at the extreme base. 



(J . As in the female ; but the margins of segments 4-7 

 are black instead of ferruginous. The first recurrent nervure 

 is received at the middle of the second cubital cell, the 

 second at one-quarter from the base of the third cubital cell. 

 The submedian cell is no longer than the median. In both 

 sexes the mandibles are black at the apex.

Hab. S.W. Persia [Escalera). 



Very near S. glasu/iovii, Mor., but in the present species 

 the second joint of the flagellum is distinctly longer than the 

 third, the tegulse are less strongly punctured, the metapleurte 

 are not striated, the colour also differs considerably. 1 have 

 not seen specimens oi glasunovii, and it is possible that the 

 differences may prove to be of subspecific rather than of 

 full specific importance. The slight differences in neuration 

 between the sexes are remarkable. 



The ? is the type.
