broad curved dark band across each wing beyond the middle, including 

 a portion of the fringe but broken by the absence of dark scales on the 

 third long vein. The band is darkest on the costal and first long veins. 

 There is also a triangular dark area with its base on the lower quarter 

 of the costal vein and its apex on the fourth long vein. The space be- 

 tween these two dark areas is of a richer golden-yellow than the rest of 

 the wing. A small black spot at the extreme base of the wing near the 

 origin of the long veins. Halteres pale yellow. Legs black, very hairy, 

 with apical bands of bright yelow hairs on all the joints. Many yellow 

 hairs interspread with the black ones, especially on the feet. Femora 

 slightly swollen. Ungues much curved, simple and equal. 



Male. — Antennae pale yellow; basal and second joints as in the 

 female; all the following joints, including the swollen terminal one, 

 with well-developed basal verticels of long hairs; there are also many 

 long fine hairs arising along each joint; on the last three joints these 

 are much shorter. Ungues equal and simple. Length : One and one- 

 half mm. 



Adult larva. — Head pale yellow, compressed antero-posteriorly. An- 

 tennas inserted close together at the front of the head, folded back and 

 hidden along the anterior border, only the three apical spines projecting 

 forward ; apical spines slender, curved, the longest nearly half as long 

 as the shaft, the other two slightly shorter; inserted with them a short 

 comb-like appendage. Spines of the lateral sclerite about fifteen, stout, 

 not inserted upon a ridge, the larger obsoletely serrate along their con-

cave borders. Labium with thirteen teeth ; the outermost pair very 

 small, the next four pairs progressively larger; central tooth as long 

 as the longest of this series ; tooth on each side of the central one only 

 half its length. Mandibles with seven stout teeth, the two innermost 

 largest. Thorax and abdomen glabrous; colored a pale purple, rather 

 darker laterally. Eighth and ninth segments not pigmented. Thorax 

 elliptical, broader than the head. First abdominal segment very short, 

 second widest, seventh and eighth segments much attenuated. Three 

 large simple setae on each side of the two first abdominal segments ; 

 a pair on each of the following to the seventh, which has no long 

 lateral setae. A stout subventral hair on each segment from the third 

 to the sixth, arising near the posterior border. Subdorsal hairs appar- 

 ently absent. A group of several stout branched hairs at the posterior 

 lateral border of the eighth segment. Tube stout, compressed, about 

 half as long again as wide; a pair of branched hairs at the back below 

 the middle, not reaching to the top of the tube ; at the posterior aspect 

 of the summit there is a small simple straight hair on each side; in front 

 of this nearer the side is a stout spine, arising from a prominent 

 tubercle, and curved inwards at its apex; a little in front of this again 

 a large pyramidal tubercle with a thorn-like apex and a conspicuous 

 black pigment spot near the top, it has also a long and stout subapical
