where it meets the yellow fringe ; a few short yellowish hairs 

 projecting from the under surface of the scutellum posteriorly. 

 Abdomen reddish chestnut, the sides of the last three segments 

 below, as well as more or less of the anterior portion of the 

 third, greyish pollinose ; the first four segments thickly clothed 

 with short, appressed, silky hairs of a ferruginous hue; the fifth 

 segment thickly clothed with longer golden hairs ; the second 

 segment with an oblong patch of black hairs on each side, 

 occupying only the anterior two-thirds of tlie segment, and not 

 descending far down the sides ; it is probably to these patches 

 that Macquart is referring when he states, " premier segment 

 noir, ^ bord postdrieur fauve ; " a triangular area in the centre 

 of the second segment also clothed with short black pile, 

 reaching to the posterior margin in the median line, and 

 surrounded on each side by a tuft of longer yellowish-orange 

 pile starting from the posterior margin of the first segment ; 

 central portion of third segment near the posterior margin with 

 an ill-defined black band, due to short black hairs mingling 

 with the ferruginous ones; posterior margin of second and third 

 segments narrowly whitisli. Legs: first two pairs of coicrn 

 black, greyish pollinose, the anterior pair clothed externally 

 with pale yellow hairs and in front with black hairs, the 

 middle pair clothed externally with yellow hairs, mingled 

 with which are a few black ones ; posterior coxse black, 

 reddish brown behind, clothed externally with a tuft of yellow 

 pile and at the extreme base with black hairs; femora, 

 tilice, and tarsi brownish black, clothed with black hairs ; 

 the anterior femora and the posterior side of the others at the 

 base reddish brown ; the bases of the femora, posteriorly in 

 the case of the first two pairs and anteriorly in that of the 

 the last pair, yellowish pollinose and clothed with yellow 

 pile ; bases of the middle femora also with traces of yellow 

 pollen above and anteriorly, those of the last pair posteriorly 

 slightly yellowish pollinose and with a few yellow hairs. 

 Wings, alulce, and squamce very dark brown, the latter with 

 a fine border of extremely short yellowish pile ; wings not 

 very large for the size of the insect, covered with conspicuous 

 transverse wrinkles ; alulcB large, subquadrate in shape, 

 strongly wrinkled, and very conspicuous when the insect is 

 viewed from the side with the wings at rest.
