structure is utterly different in many points, especially the 
form and colour of the clypeus in both sexes, the sculpture of 
the basal area of the median segment, the form of the pygidial 
area in the female and the presence of spines on the sixth 
sternite of the male.

tertio fascia basali interrupta flavis; clypeo apice, mandibulis, 
apice excepto, antennis, intra medium et apicem fuscis, orbitis

Long. 16 mm. 
¢. Hyes slightly convergent towards the clypeus. Apical 
joint of the flagellum scarcely as long as the penultimate, 
very feebly curved. Clypeus broadly and very shallowly 
emarginate at the apex, feebly convex, closely microscopically 
punctured. ‘Thorax and median segment very closely and 
not very finely punctured. Abdomen closely punctured, 
finely on the basal, more strongly on the apical segments ; 
seventh tergite broad, rounded at the apex, the sides distinctly 
sinuate. first transverse cubital nervure slightly curved 
near the cubitus. The hyaline margin of the wing reaches 
beyond the third transverse cubital nervure and beyond the 
second recurrent nervure.

This belongs to the group of S. fasciatus, Fabr., but the 
colouring is very different and the seventh tergite more dis- 
tinctly sinuate at the sides. The description of S. pictus, 
Dahlb., taken from a female, somewhat resembles this species, 
but the three apical abdominal segments are said to be flavo- 
testaceous. SS. pictus seems to be unknown to recent authors; 
it is also an Egyptian species. he tergites of the present 
species are in certain lights tinted with fusco-castaneous.
