median longitudinal stripe appearing only to reach the middle of 
the thorax, and lastly a short lateral stripe beginning opposite the 
termination of the median one, underneath each humeral patch, 
and extending to the scutellum (in a certain light these short 
stripes appear to form a fork with the median stripe) ; pleurae 
ochraceous-brown, almost covered with white decumbent scales ; 
scutellum adorned with long white scales and very long yellow 
hairs ] metanotum ochraceous-brown, almost hoary when viewed 
at a certain obliquity. Halteres pale ochre-yellow. Abdomen 
whitish, two and a half times the length of the thorax, densely 
clothed with long white decumbent and erect scales and long 
yellow hairs, each segment bordered posteriorly with a broad 
band of pale yellow, in the last two or three segments apparently 
represented by two lateral patches ; beneath covered with white 
decumbent scales, the segments posteriorly bordered with 
bicoloured scales, the basal half of each being pale yellow and 
the apical portion umber-brown ; forceps densely covered with 
scales and long yellow hairs, basal joints brown, the terminal 
hooks yellow, very long and incurved. Legs pale ochre-yellow, 
densely covered with long semi-erect scales interspersed with long- 
yellow hairs, making them appear more than twice their real 
thickness ; coxse brownish-ochraceous, more or less covered with 
white scales, the remaining joints ringed with white and 
bicoloured scales alternately, the colours of the latter as on the 
abdomen; the dark rings on the femora and tibiie much broader 
than the white ones, both about equal width, or the latter some- 
what wider, on the tarsi. Wings about the length of the abdo- 
men, hyaline, veins yellow covered with a mixture of white and 
bicoloured .scales (similarly coloured to the above-mentioned), the 
marginal cilia in grey and white patches alternately ; rather 
weakly iridescent. Auxiliary vein joining the costa opposite 
the tip of the posterior branch of the fifth longitudinal vein ; 
sub-costal cro.ss-vein much nearer the origin of tlie second longi. 
tudinal vein than to the luimeral cross-vein ; middle cross-vein a 
little shorter than the posterior cros.s-vein, almost in line with one 
another, situated over the middle of the jmsterior branch of the
