brown bands ; costal border testaceous. 2 8J lines. PI. iii, figs, i 

 and 2. 



Head ochre-yellow, below with some coloured pubescence ; the 

 forehead very narrow, stripe shaped, with a black median line 

 hardly broader below. Byes naked, bronze coloured, without 

 markings. Antennae cinnamon-brown, the first joint ending in a 

 point, above the second very short, prolonged above in a thorn-like 

 point, the third moderateh^ incised above. Palpi ochre-^^eilow. 

 Thorax and scutellum blackish with Ochre-yellow tomentum and 

 on the breast sides with conspicuous ochre-yellow pubescence. 

 Abdomen black-brown, with thick pale ochre-yellow almost golden 

 yellow tomentum, which leaves the fore borders of the segments 

 tolerabl}^ wide, so that cross-bands more or less darker are formed, 

 somewhat broader at the sides. lyCgs black, the coxae the same 

 colour as the abdomen, and the ground colour of the femora 

 becomes more or less modified owing to the rather thick ochre- 

 yellow pubescence. Halteres yellow. Wings with greyish ground 

 colour and black-brown veins ; the base and the marginal cell 

 brown-yellow; a brown shadow lies across the transverse veins, 

 which forms a narrow half zigzag band in the middle of the wing, 

 and on the last third of the wing appears a broad brown cross- 

 band, which stretches from the fore border at the ending of the 

 first vein to the upper branch of the third longitudinal vein ; this 

 band, which becomes paler on the posterior border, is rounded on 

 the inside and outside towards the apex of wing notched triangu- 

 larly, the angle of the third vein has no appendix; the first 

 posterior cell is closed at the border with a short stalk. Celebes

 obscurely yellowish, the hind tibiae obscurely reddish yellow, 

 the pubescence on coxae and femora yellow with grey tomentum , 

 black on the tibiae and tarsi, the hind tibiae with black fringes.

 hairs, the third long and slender with a small tooth, slightly dusky 

 at tip. Abdomen more yellow than in female, the darker bands only 

 beginning on the fifth segment, the segmentations narrowly whit-
