 antennae; the vertex, which is deeply cut away behind, mainly 

 occupied by a large velvet black spot with a semicircular outline 

 on its lower part. A very large semicircular velvet black spot on 

 each side of the frons, widely separated from the vertical spot, 

 but absolutely contiguous throughout its whole width with the eye 

 margin, and contiguous to the base of the antennae, the interval 

 between the two spots being equal to one- fifth the width of the 

 frons at that spot. Ocellar spot brought well forward on the 

 frons, contiguous to the lowermost edge of the vertical black 

 spot; it is blackish, the ocelli pale 3^ellow. The frons proper 

 bears two pairs of dorso-central strong curved bristles, the lower 

 pair situated at the middle of the inner margin of each large 

 frontal spot, the upper pair placed in a line with the lower edge of 

 the vertical spot, but separated from both it and the eye margin. 

 A third pair of bristles is vertical, between the upper corners of 

 the vertical spot and the eye margin. Behind these, and distinctly 

 behind the vertical margin, is another pair. Antennae yellow, 3rd 

 joint elongate-oval, with rounded tip, the upper and outer edge 

 blackish; the arista black, long plumose on upper side, bare on 

 underside except for a few short hairs towards the tip The face
