a distance equal to rather more than twice the length of tiie 

 scape on the clypeus and by fully three times the length of 

 the sca|)e on the vertex. Posterior ocelli distinctly further 

 from each other than from the eyes. Clypeus sparsely punc- 

 tured, widely emarginate at the apex, more than half as long- 

 on the median line as the breadth at the base; the exposed 

 portion of the labrum a little shorter than the clypeus and 

 broadly rounded at the apex. Antennai separated from the 

 base of the clypeus by a distance equal to about two-thirds 

 of the length of the scape; the tlagellum gradually thickened 

 towards the apex, the second joint nearly t vo and a half 

 times as long as the third. Thorax and median segment 

 subopaque, closely punctured; the abdomen shining and more 

 finely punctured, slightly iridescent. Ventral segments 

 sparsely punctured, unarmed. Hypopygium with the usual 

 three a[)ical spines. Second abscissa of the radius very 

 little shorter than the third ; second cubital cell receiving 

 the first recurrent nervure slightly beyond the middle and the 

 second just before the apex. Submedian cell of the hind 

 wing extending tar beyond the origin of the cubital nervure. 

 Anterior tarsi distinctly ciliated, the basal joint with four 

 rather short spines, the apical spine with another shorter and 

 slenderer beneath. Anterior tibiio smooth, intermediate and 

 posterior tibii© feebly spinose. The hyaline area on the ante- 

 rior wings is very small, commencing at the apex of the 

 radial cell and ending on the outer margin of the wing a 

 little below the cubitus.

This belongs to the group tridentatus, Fabr., and is most 

 nearly allied to melanopterus, Dahlb., and ci/anipennis, 

 Sauss. It differs from the former in the less coarsely punc- 

 tured thorax, the much longer second abscissa of the radius, 

 the somewhat broader clypeus, and the presence of a hyaline 

 area at the apex of the wing ; Irom the latter, which I have 

 not seen, and which is only known in the female sex, in the 

 colour of the wings and antennai and the absence of a carina 

 on the first dorsal segment. Iladoszkowsky's description is 

 short, but the points he mentions in comparing his species 

 with melanopterus leave little doubt in my mind as to the 

 correctness of my identification.
