lit vertex about one-fifth of the greatest width of the head, 

 broadening distinctly to base of antennae. Thorax bhick, with a 

 coating of very small oblong brownish scales lying fiat on the 

 surface, and a further clothing of dense short bright cfirome-yellow 

 hair-hke scales covering (presumably) the entire thoracic and 

 scutellar dorsum, this vestiture being a little shorter and longer 

 towards the sides : pleurae covered (apparently entirely) with 

 similar scales of greyish-white colour. Abdomen black, with a 

 layer of small brownish scales as on the thorax, and a clothing of 

 closely-placed, moderately elongate, yellow overlapping scales, 

 evidently covering the entire dorsum and sides in perfect speci- 

 mens ; sides of 2nd segment with four or five long, slightly curved, 

 yellow bristles. Venter bearing at least a broad median stripe of 

 similar scales, which are greyish white ; hind margins and sides 

 of all tiie segments with small bright yellow scales ; whole venter 

 sometimes covered with small whitish scales, more densely so on 

 hind margins of segnients. Lcffs black ; coxte with white scales 

 on front sides, hind pair witli three long yellow bristles on outer 

 sides ; femora and tibiae closely covered with small brown scales 

 as on. the body ; anterior femora on hinder and undersides, hind 

 femora on outer and undersides, with small overlapping silvery- 

 white scales ; hind pair witli a few small black bristles below ; 

 tibiae with several rows of strong bristles, outer sides with small 

 depressed wiiitish scales, their extent apparentl)^ variable; all 

 tibiae on inner side with a row of rather longer, dark brown, 

 somewhat outstanding scales, and with a circlet of apical spines ; 

 tarsi black, with short black bristles below. Under moderate 

 microscopic powder the whole surface of the tarsi is seen to be 

 covered with extremely minute black scales. Winc/s grey, more 

 or less brownish on anterior part, sometimes distinctly so as far 

 hind wards as the 4th longitudinal vein ; sometimes the colouring 

 much restricted or almost entirely absent, leaving only the trans- 

 verse veins slightl}' suffused ; halteres pale brownish yellow ; 

 thoracic squamae whitish, with a long fringe of white hairs. 



Length, 5-6 mm. (excl. anteniue).

The colour of the body- scales in this species is sometimes 

 uniformly bright yellow and sometimes wholly snow-white ; in 

 some specimens scales of both colours are present in variable 

 proportions, tliose on the thorax and forming a broad median 

 stripe on the abdomen being yellow, whilst those on the pleurae 

 and sides of tiie abdomeu are white. Probably in perfect 

 specimens the whole thorax and abdomen are covered with scales ; 

 but when a specimen is partly denuded, the form usually taken is 

 of a median and lateral stripes of scales and more or less complete 

 tr.msverse bands of them on the hind margins of the segments.
