hmujUi : 3 111111. 
Ihihildl : Upper White Nile, taken on steamer. (H. King.) 
Ohsemitions: Described from two males and two females caught hy Mr. King. 
It resembles to some extent .1/. iiniformia, Theoh., but can at once be told by the pale 
area around the central dark area of the thorax and by the wing venation. 
The long second segment of the female antemuc I did not notice in I/, uniftinnis, hut 
if it occurs it forms a marked generic character. 
Genus, Vrandlieuia, .Vrrihalzaga

mesothorax ; a white line on each side in front of the roots of the wings ; prothoracic lobes 
white scaled. Abdomen brown, unhanded, with apical lateral pale spots. Legs unhanded,

curved l)ronzy scales; a white-scaled 
line on each side in front of the wings 
and a line of white scales extending 
from the scutellum to the middle of the 
mesothorax; sides somewhat paler ; 
scutellum paler than mesothorax, with 
small flat dark scales, some white ones 
extending on to the mid lobe from the white line in front; tour large black bristles to 
the mid lobe and one small central one ; metanotum deep brown; pleuriE testaceous,

fourth, where there are lines of flat white scales ; large clavate scales on the apical portions 
of the second and fourth and on all the third ; fork-cells small and wide, the first smaller 
than the second, its base much nearer the apex of the wing than that of the latter, its stem 
about three times the length of the cell ; stem of the second fork-cell about one and a half 
times the length of the cell ; mid and posterior cross-veins about equal in length, the latter 
more than its own length distant from the mid ; sixth long vein broadly curved towards 
the costa. 
Length : 2-5 to 3 mm. 
Habitat: Upper White Nile, taken on steamer. (II. King.) 
Observations: Easily told from the following by the pale scaled head, and liy the wing 
venation. The head scales show dull purple shades behind in some lights. 
The thoracic adornment resembles the next species to some extent.
