cate and inconspicuous greyish-yellow hairs: the hiiid niargins of 

 the four basai segments possess each a row of adpressed white hairs, 

 and those on the hind margin of the 5th segment are much longer, 

 less adpressed, and brown; ail the abdomen possesses in addition an 

 inconspicuous dark brown pul)escence. 



Legs brown and yellow; front and middle feniora very dar!-. 

 brown except at the extrême tip which is yellowish-brown, and the 

 front tibiae yellow, except for a short distance on the outer mai'gin 

 near the base which is dark brown; middle tibiae witli their liasal 

 halves blackish-brown ; hind legs with the femora entirely black 

 and the tibiae black except their apical thirds which are yellow; ail 

 the tarsi wholly yellow. The pubescence on the legs is médium and 

 for the most part dark brownish 



Wings with their basai halves dark and their apical halves 

 almost without markings; thèse consist only of five brownish-black 

 narrow bands and spots of varions colours which show through the 

 blackish-brown ground colour of the basai half ; the first band which 

 is the shortest, thickest and darkest, is situated before the middle 

 of the wing and extends from R2 + 3 crossing RI vertically, covering 

 the stigma to the costa and its outer margin ending with the pro- 

 jecting extremity of the costal cleft; the second band, immediately 

 after the middle of the wing runs up vertically from R4 + 5 to the 

 Costa with its apical third covering the tip of R2 + 3; the third, 

 fourth and fifth bands seem to originate from one main band run- 

 ning over R4 + 5 and ending at ahout three-quarters of the length 

 of this vein by the bifurcation of the third and fourth bands; the 

 third runs outwardly and upwards to the costa and the fourth down- 

 wards and outwardly to the lower wing margin covering the end of 

 Ml; the fifth band is short, vertical, situated exactly beneath and 

 in a straight line with the second band ; the most conspicuous of the 

 spots on the basai half is a deep yellow rounded spot between R2 + 3 

 and R4 + 5; in addition, there are three dark reddish-brown spots, 

 one elongated and triangular, between R2 + 3 and R4 + 5 (almost 

 touching the deep yellow spot), the second oval, at the end of Ist M2 

 cell, and the third, which is the smallest, immediately after the 

 médian cross-vein in 2nd M2 cell with its upper margin touching 

 Ml ; the arrangement of the white spots is as follows : one large spot 

 above the deep yellow one; one elongated and rather pointed below, 

 just before the stigma; one small spot entirely covering the very in- 

 conspicuous radio-median cross-vein; one fairly large and elon- 

 gated spot near the base and lower end of 2nd M2 cell ; one small 

 spot in Ist M2 cell; three small and one larger round spots in Cul 

 cell; three small and one larger round spots in Cul cell, and two 

 small rounded spots in 2nd A cell: in addition there is a small 

 black spot at the apex of R4 + 5.
