(Dipt. Hal. Prodro. vol. i. (188G), Rondani; Bull. Soc. Ent. Ital. p. 212 (1890) ; 
Yenti Spec. Zan. Ital. p. 146 (1899), Ficalbi.) 
(Fig. 60, PL XV.) 
Thorax umber-brown with a median line of white scales, a 
bent white lateral line and another more indistinct on each side 
below. Abdomen yellow scaled, with scattered black ones which 
form patches or may predominate ; basally banded white, the 
bands extending backwards in the middle of the second and 
third segments and produced laterally ; subject to some variation 
in arrangement. Legs dark, femora, tibiae and metatarsi with 
lines of white spots or stripes, metatarsi and some of the tarsi 
basally white banded. Wings with more or less distinct patches 
of scales, three in number. 
9 . Head almost black, with two median curved lines of 
white scales, which unite in front and behind and pass as a 
white line between the eyes ; there is also a line of snow-white 
scales bordering the eyes ; bristles dark brown, arising in 
numbers from the two black bare spaces between white scaled 
areas, and at the back of the head are a few brown upright 
forked scales; antennae brown, with pale pubescence, basal 
joint testaceous, with snow-white scales, as have also the second 
and third joints on the inside ; palpi black, with a few white 
scales, pure white at the apex; proboscis black; clypeus 
testaceous. 
Thorax umber-brown, with thin hair-like bright umber- 
brown scales, and shows a dark central line when denuded ; over 
this is a median line of white scales which passes back close to 
the scutellum, where it forks round a small bare space; this line 
originates in a clear white central spot in front; on each side is 
another curved line of white scales, which bends in over the 
mesonotum about the middle and runs back to the scutellum ; 
beneath these is another indistinct line of a similar colour, two 
small white spots are seen in front formed by white scales on the 
two prothoracic lobes; there is also a white patch of scales over 
and just before the wings; numerous black and pale golden 
bristles at the sides; scutellum with white scales; metanotum 
chestnut-brown; pleurae pale yellowish, with three more or less 
distinct bands of white scales formed by a continuation of the 
white scales on the coxae.
