$ . Eyes rather hairy ; the black pimctulate frons and epistoma are wide, the 

 middle knob of the latter shining, they are clothed with abundant erect black hairs, 

 slightly longest on the frons, and leaving the middle of the epistoma bare ; the face 

 is rather descending, the eyes extending downwards much less than usual, leaving 

 the cheeks imusaUy broad ; in profile, the frons appears inflated, the epistoma 

 descending straight to the slight, but distinct middle knob ; the wide cheeks are 

 clothed with black hairs, but the cilia round the back of the head are pale yellow ; 

 thers is a bare-looking space on the lower half between the back of the head and the 

 eyes, which, however, in another light, is seen to be clothed with numerous short 

 black hairs ; the vertex is clothed with rather long black hairs, yellow behind on 

 the occiput ; the antennaj are pitchy-black, the third joint often with a brownish 

 reflection, the arista bare. 



Thorax dull black, faintly punctate, clothed with a long, tolerably abundant 

 pubescence, except on the fore part (this pubescence is generally all pale yellowish 

 except just about the base of the wings, but smaller specimens frequently have the 

 pubescence nearly all black ; on the breast-sides it is long, shaggy, and black) ; the 

 Bcutelliun is brownish, rather dull, with an extra long yellow pubescence round the 

 edge, more whitish on the disc ; alulffl pale yellow, their edges and the knob of the 

 halteres yellow. Abdomeia rather dull bluish-black, rough but scarcely punctate ; 

 near the basal corners of the third and fourth segments are elongate yellow spots 

 not touching the fore margin, and only indistinctly, if at all, connected with the 

 edge ; the hind margins of the fourth and fifth segments are obscurely reddish ; 

 the pubescence round the edge is all long, black, except at the base of the third, 

 fourth, and fifth segments, where it is yellow, on the disc are scattered yellowish 

 hairs ; the genitalia are black and rounded, with black pubescence ; belly dull 

 blackish, the spots shining through obsciu-ely. Legs pitchy-black, front tibice very 

 slightly brownish ; pubescence on the front femora long, abundant, black at the tip, 

 yellowish about the base, on the middle pair not quite so abundant, and on the hind 

 pair there is a slighter yellowish pubescence in front near the base, and a short.
