at bases, cross-veins very indistinctly clouded. Calyptrze 
and halteres yellowish. 
Male.—Kyes bare, separated by more than twice the width 
of third antennal segment ; orbits setulose to middle, wider 
than narrowest part of interfrontalia; ocellars very long ; 
parafacial almost linear; cheek higher than width of third 
antennal segment, the latter nearly twice as long as second 
segment; longest hairs on arista as long as width of third 
antennal segment. Thorax with three pairs of dorso-centrals 
behind suture; prealar absent ; sterno-pleurals 2:2; hypo-

on basal half of postero-ventral surface; mid-tibia with two 
or three posterior bristles; hind femur with a few bristles on 
apical half of antero-ventral surface and one or two shorter 
bristles on basal half of postero-ventral ; hind tibia with one 
antero-ventral and two antero-dorsal bristles. Outer cross-

Belongs to the same group as duplicata, Meigen, but I

Helina lucida (Stein). 
Mydea lucida, Stein, Ann. Nat. Mus. Hungar. xi. p. 493 (1913). 
This species and the next one belong to a group closely 
allied to the preceding one, the abdomen being largely 
yellowish pellucid with similar black marks, but both have 
the thorax with conspicuous black marks and the eyes of the 
male are more widely separated, the frons being distinctly 
wider than the width of the third antennal segment. The 
postsutural transverse black fascia on thorax m lucida is 
entire, while in the next species it is more or less distinctly 
interrupted on each side of the median line, the fascia
