c? . Head yellowish ; three distinct, rather large, round black 

 spots on frons, carrying the ocelli, the middle one of which is 

 slightly smaller than the others and placed rather above them on 

 the frons ; each also carries a bristle, the outer ones being very 

 large and conspicuous ; all the rear part of the head behind the 

 ocelli with short, stiff, bristly brown hairs ; face and palpi yellowish, 

 former with brown hairs. Antennal scape and first ten joints of 

 flagellum yellowish, the remainder black. Thorax brownish 

 yellow, with three darker brown stripes, the median one faint, 

 formed of two narrowly separated fine lines, the outer ones pointed 

 at each end ; all three attain the hind margin of the dorsum, the 

 middle one being continued over the concolorous scutellum, which 

 bears four bristles on its hind margin. Metaiiotum brownish 

 yellow, with a pair of longitudinal blackish stripes ; sides of thorax 

 concolorous. Abdomen black on dorsum, pubescent ; base pale ; 

 belly yellowish, except at the tip. Genitalia subglobose, yellowish, 

 apparently twisted sideways ; the basal joints obtusely conical, 

 with a pair of intermediate small black horny hook-like appen- 

 dages and an elongate narrow dorsal style. Legs brownish 

 yellow, tibiae a little darker, posterior tibiae beset with bristles. 

 Wings yellow, a little paler behind ; venation normal, veins 

 yellow or yellowish brown. A brown mark over the tip of the 

 3rd longitudinal vein, extending a little in front of the vein at the 

 margin of the wing, and a little behind the vein at a short distance 

 from the wing-margin. Halteres yellow, with a short thick stem, 

 clubs black-tipped.

 each side of the dorsum a very large, pear-shaped, shining, jet- 

 black spot, extending from a little below the shoulders to the 

 posterior corners, and from the wing-roots nearly to the middle 

 of the dorsum, leaving only a narrow yellow interval between the 

 two spots. Thorax covered with loose shaggy yellow hairs, 

 amongst which there are several bristles along the lateral borders 

 of the dorsum, strongest above the wings ; two dorso-central
