The wings are a little longer than in dakarensis, Buyss., 

 but much shorter than in perornata. Turn. In the latter 

 species the stigma is placed much further from the base of 

 the wings. 



Myzine pGlitissima, sp. n. 



^ . Niger, nitidus, punctatus ; abdomine subtilissime punctato ; 

 clypeo emarginato ; mandibulis, clypeo, scapo siibtus, pronoto 

 antice et postice, segmentis abdominalibus fasciis latis apicalibus 

 flavis ; alls hyalinis, nervulis nigris, stigmate testaceo ; pedibus 

 flavis. 



Long. 14 mm. 



c^ . Clypeus widely and shallowly emargiuate at the apex, 

 nearly twice as broad as long, and produced at the lateral 

 angles into a short spine projecting over the base of the 

 mandibles. Head, thorax, and median segment finely and 

 closely punctured, shining ; with rather long white pubes- 

 cence, which is very close on the front, posterior margin of 

 the head, mesopleurse, and median segment. Pronotum 

 as long as the mesonotum, strongly narrowed anteriorly. 

 Posterior ocelli widely separated, further from each other 

 than from the eyes ; all the ocelli small and situated on the 

 sides of deep depressions. Median segment obliquely sloped 

 posteriorly. Abdomen shining, minutely and shallowly 

 punctured, the segments not constricted ; basal segment 

 with a narrow petiole forming the basal third, the apical 

 two-thirds as broad as long, slightly swollen and only a little 

 narrower than the second segment ; segments 2-6 very much 

 broader than long ; the apical dorsal segment convex, deeply 

 emarginate at the apex, the emarginatiou deeper than the 

 breadth at the apex, the lateral processes rather narrowly 

 produced, bluntly pointed at the apex. Posterior tibia as 

 long as the first joint of the posterior tarsus plus half of the 

 second joint. Second abscissa of the radius slightly longer 

 than the third. 



Black ; mandibles, except at the apex, clypeus, scape 

 beneath, the apex of the prominence above the base of the 

 antenuse, the anterior and posterior margins of the pronotum 

 broadly, a broad apical band on each dorsal segment and on

This male may be distinguished from all others known to 

 me by the shining and almost impunctate abdomen.
