hairs. Scutellum yellow, with yellow hairs, at the apex generally a 

 few black hairs. Pleura æneous, shining, a spot above front coxæ, 

 the greater part of meso- and pteropleura, metapleura and the upper 

 part of sternopleura yellow; the pleura are sparingly clothed with 

 yellow hairs. Abdomen long and narrow, distinctly longer than the 

 wings; it is dull black with yellow markings, the first segment and 

 the apex shining; the side margin all yellow; the second segment has 

 a yellow band in the middle, which may be more or less emarginate 

 and sometimes narrowly interrupted, at the sides it slopes backwards 

 and reaches the margin with the hinder corners; the second band is 

 similar but nearer the front margin and broader, it is not or slightly 

 emarginate, and likewise sloping at the sides and reaching the yellow 

 margin; the third band is likewise broad but for the rest rather 

 varying, generally it is emarginate in front and thus bilunulate, and 

 also rather deeply emarginate behind and here produced on each side 

 of the emargination ; sometimes the described shape is less pronounced, 

 and the band may be interrupted thus forming two lunulate spots; 

 its hind corners reach the side margin ; the hind margin of the fourth 

 segment is indistinctly orange; fifth segment orange with an abbrev- 

 iated and pointed black middle line on the front part, and two some- 

 what triangular spots at the basal corners, one at each side, and two 

 triangles inwards to the hind corners ; hence the yellow colour, besides 

 the margin, forms something like an M ; or the two spots on each 

 side are larger and united, and then the pale colour forms a V; some- 

 times the markings on the last segments are less defmite, the black 

 and yellow colour running somewhat together, and the yellow colour 

 more extended. The hairs on 

 abdomen are short, they follow 

 to some degree the ground colour, 

 but are black along the dorsum 

 and at apex; at the sides they 

 are long at the base and yellow, 

 at the hind corners of second 

 and third segments are some 



black hairs and on the apical T^,of^a • ^ , i

yellowish, sometimes partially 



darkened, with longish, pale hairs. Genitalia large, reddish yellow, 

 the eighth segment has two black spots, one above the other, and 

 the ninth segment two blackish spots at the base; the ninth segment, 

 the hypopygium, is oval, considerably longer than broad; the apical 

 appendages or lamellæ are less distinctly bifurcate, the lower branch
