silvery white tomentum ; frontalia cinereous, slightly widening 
towards the antenne, with a row of black bristles on each 
side; one long bristle and a few short bristles on each side 
of the epistoma, which is hardly prominent. Eyes bare. 
Palpi testaceous. Antenne not reaching the epistoma; 
second joint red at the tip; third linear, hardly more than 
twice the length of the second; arista very much longer than 
the third joint, stout for nearly half the length from the base. 
Thorax and abdomen with cinereous tomentum; a few 
bristles on each side. Abdomen elliptical; first and second 
segments towards the hind border and third wholly black and 
shining. Wings cinereous; veins black; prebrachial emit- 
ting a branch and forming a slightly obtuse angle at its 
flexure, nearly straight from thence to its tip, which joins the 
costal vein at some distance from the tip of the wing; discal 
transverse vein undulating, parted by a little less than its 
length from the border and by much less than its length from 
the flexure of the prebrachial; alule white. Length of the 
body 3 lines. This species is referred with doubt to the 
genus Frontina. Wady Genneh.

66. M. minuscula. Female. Black. Head silvery white ; 
frontalia tawny, linear, with a few short bristles on each side ; 
facialia without bristles. Eyes bare. Antenne setaceous, 
not near reaching the epistoma; third joint full twice the 
length of the second; arista stout, a little longer than the 
third joint. Thorax and abdomen with a few bristles on each 
side. Thorax cinereous. Abdomen red, with four black 
bands; third and fourth broad; fourth apical. Legs black. 
Wings pellucid; veins pale testaceous; prebrachial vein 
forming a slightly oblique angle at its flexure, near which it 
is slightly bent, aud is thence straight to its tip, which joins 
the cubital vein at some distance from the tip of the wing; 
discal transverse vein straight, parted by more than its length 
from the border, and by less than its length from the flexure 
of the prebrachial; alule white. Length of the body 23 
lines. This species perhaps belongs to a distinct genus.
