 middle and white at the sides, a narrow white border due to reflection around the eyes, 

 thick black chiBtte project over the eyes inwards ; palpi black with snow-white apices ; 

 proboscis and antennae black. Thorax black, clothed with small narrow-curved black 

 scales, in front on each side a large silvery-white triangular patch of broader scales, 

 behind this a smaller patcli just in front of the roots of the w-ings ; from the middle of the 

 mesothorax run backwards two parallel thin yellow lines and two sub-median snow-white 

 ones, the latter quite reaching the scutellura ; chaetae jet black ; soutellum clothed with 

 flat silvery-white scales, dusky in some lights ; metanotum brown ; pleurae black with 

 three prominent silvery-white spots of flat scales. 



Abdomen black, the second segment with trace of white basal band, the third, fourth, 

 fifth and sixth with prominent silvery-white basal bands, the seventh with two white 

 basal spots, eighth dark, also the basal segment ; chiBtae and border-bristles black ; venter 

 with broad white basal bands. 



Legs, black, the fore and mid metatarsals and first tarsals with Inisal white bands, 

 rest of tarsals black ; in the hind legs the femora are pale on the basal half, the black 

 apical half with two silvery-white spots, one apical, the metatarsi and first and second 

 tarsals with basal snow-white bands, the third all dark, the fourth white. 



Wings with dark scales, especially along the outer costal border; fork-cells rather 

 short, the first longer and slightly narrower than the second, its base slightly nearer 

 the base of the wing, its stem about half the length of the cell, stem of the second 

 posterior not quite as long as the cell ; posterior cross-vein about the same length as 

 the mid, about its own length distant from it. 



Length, 4:'5 mm. 



,^ Head as in the !(? ; palpi as long as the proboscis, blunt, no hair tufts, a few black 

 bristles, black, a ventral white area at the base of the apical segment, a broad median 

 white band and a narrow basal one ; antennte banded black and white with black 

 plume hairs. 



Thorax as in the 5^, but the median thin yellow lines curve around the bare space 

 in front of the scutellum and reach it, the last part being composed of broader

Head clothed with flat scales, except for a small group of minute luirrow-curved 

 ones on the nape, and a larger group of upright forked scales. Proboscis swollen on 

 the apical third, composed of two segments, the joint at the apical third ; labella acuminate. 

 Antennae of $ densely plumose with two very long terminal segments pilose only ; other 

 segments thick, basal one globular ; palpi of male a little longer than the proboscis, clavate 

 at the apex ; of two segments the apical one short and clavate ? with ventral chaetae and 

 two large and some small apical ones. Palpi of $ about one-fourth the length of the 

 • This probably also occurs iu the 9 as there are traces of these larger scales.— F.V.T.
