5 . Head wholly bright sulphur-yellow. Frons and face fully 

 one-third of head, very slightly narrower at about middle of irons ; 

 frous rather broader on lower part; eyes bare; upper eye-margins 

 of frons narrowly black ; a thin line running from the corner of 

 each eye diagonally to vertex at each side of vertical spot ; au 

 elongate black spot on vertex., embracing the ocelli, pointed at 

 anterior end ; an oval or leaf-shaped one of moderate size in 

 middle of frons and a small elongate, vertically placed one imme- 

 diately above base of antennae ; the latter wholly brownish orange, 

 of normal size ; arista black ; lower sides of face (viewed from 

 above) with snow-white shimmer ; mouth-region and proboscis 

 brownish orange ; postocular orbit very broad, lower part with 

 whitish shimmering tomentura and microscopic pubescence ; occi- 

 put black. Thorax sulphur-yellow, microscopically punctate, with 

 very short yellow pubescence ; dorsum with three longitudinal black 

 stripes, the median one slightly the widest and reaching front 

 margin, the side-stripes just failing to reach it — all three narrow 

 and united on hind margin ; a small black vitta just above wing- 

 base. Lower part of thorax, front pai't of sternopleura and a

 microscopically punctate, emargi nations of segments very indis- 

 tinct; two broad black transverse bands, broader still in the 

 middle of each, lying apparently over the junctions of 2nd and 

 3rd segments and of 3rd and 4th segments respectively, united 

 by a short black median stripe ; the anterior transverse band 

 broadly united to the convex side of a semicircular band, which 

 has its ends on the anterior corners of the 1st segment, but just 

 failing to attain the actual margin : hinder transverse band united 

 by a median black longitudinal stripe to an arched narrower black
