$ . Mandibles rather stout, bidentate at the apex, the inner tooth 

 short and blunt ; a strong tooth on the outer side of the mandibles 

 and at right angles to them originating from the base of the outer 

 tooth. Palpi fairly stout, maxillary palpi six jointed, labial palpi 

 four jointed. Head rectangular, more than half as broad again as 

 long, shining, with a few scattered punctures ; the eyes elongate 

 ovate, touching the base of the mandibles, ocelli in a broad triangle 

 on the vertex ; the frontal tubercles above the base of the antennae 

 well developed, separated by a shallow, short, longitudinal sulcus. 

 Antennae twelve jointed, the first joint of the flagellum almost 

 concealed in the apex of the scape. Thorax smooth and shining, 

 mesopleurae rugose, propleurae punctured-rugose ; pronotum fully 

 half as broad again as long, narrower than the head ; mesonotum 

 scarcely as long as the scutellum. Median segment scarcely longer 

 than the scutellum, subopaque, closely and coarsely punctured ; the 

 posterior slope steep, smooth at the base, coarsely punctured at the 

 apex. Abdomen smooth and shining, sixth dorsal segment finely 

 aciculate, rounded at the apex. Wings short, the costa of the fore-

This fine species may be easily distinguisked by the 

 structure of the mandibles. Superficially it resembles 

 Myzine Mugii, Westw., but in that species the wings are 

 very much longer and less brilliant. The large third 

 cubital cell is present in this species as in typical Myzine, 

 but the nervures are rather ill defined ; the second cubital 

 cell is absent.

 According to Dr. Brauus these are sexes of one species, 

 appearing early in September before other species of the 

 group.
