structure is utterly different in many points^ especially the 

 form and colour of the clypeus in both sexes, the sculpture of 

 the basul areaot' tlie median segment, the form of the pygidial 

 area in the female and the presence of spines on the sixth 

 sternite of the male. 



Subfamily Stizinm. 

 Stizus anchorites, sp. n. 



cJ . Niger ; labro, scapo subtus, fronte sub antennis, tergitoque 

 tertio fascia basali interrupta flavis ; clypeo apice, mandibulis, 

 apice excepto, antennis, intra medium et apicem fuscis, orbitis 

 externis, pronoto margine postico, mesonotu lateribiis anguste, 

 tegulis, scutello, postscutello, segmento mediano fascia obliqua 

 utrinque, tergitoque primo basi obscure ferrugineis; genubus, 

 tibiis tarsisquo testaceis, posticis supra infuscatis ; alia fusco- 

 hyalinis, apice late hyalinis. 



Long. 16 mm. 



(^ . Eyes slightly convergent towards the clypeus. Apical 

 joint ot the ilagellum scarcely as long as the ]jenultimate, 

 very feebly curved. Clypeus broadly and very siiallowly 

 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. pictusy 

 Dahlb., taken from a female, somewhat resembles this species, 

 but the three apical abdominal segnients are said to be tlavo- 

 testaceous. S. pictus seems to be unknown to recent authors ; 

 it is also an Egyptian species. The tergites of the present 

 species are in certain lights tinted with fusco-castaneous.
