Male. Eye-facets in tlie upper two thirds larger than below, the 

 small facets stretching somewhat upwards along the hind rnargin. 

 The calli on face and yowls extending almost over the whole space 

 betvifeen the antennæ, mouth and inner eye-margins, leaving as a rule 

 unly a narrow, pruinose middle stripe. Antennæ black; the two 

 basal joints with long hairs. Palpi black or brownish black. Thorax 

 black with black or brownish black hairs. Abdomen black, only the 

 hind margins of the segments a little paler and sometimes with faint 

 traces of middle triangles, most distinctly soen with the light falling 

 in from behind. Venter with indistinctly paler margins of the segments. 

 Pul)escence al! black, only at the hind margins of the segments some-

 faint stripes; dark yellowish haired, especially on the sides. Abdomen
