The Genus Myiolepla. 
209 
Myiolepta; the anterior cross-vein is plainly before the middle 
of the discal cell while the petiole of the first basal cell is long 
agreeing with Syritta and with Myiolepta haemorrhoidalis Philippi 
from Chile. 
Myiolepta varipes Loew. Dark colored species with the sides 
of the first two abdominal segments more or less yellow. Length 
G-S millimeters. 
Male: Vertical triangle, a spot above the antennae, cheeks 
and facial tubercle and oral margin adjacent shining black; face 
and front otherwise black concealed bv white pollen, antenna 
pale brown, third segment nearly round, arista basal and of the 
same color as its segment. Thorax shining black with sparse 
white tomentum; wing tinged with yellowish, slightly fumose 
on anterior part near middle and at apex, first posterior cell closed 
near the margin, the petiole not half as long as the anterior cross¬ 
vein, second vein abruptly curved near the apex and meeting the 
costa at nearly a right angle; legs variable in color, femora often 
dark, nearly black, but not always, remainder of legs brown, 
although not always of the same shade. Abdomen yellow on 
the sides of the first two or three segments, otherwise black. 
The extent of the yellow of the abdomen is variable but no seg¬ 
ment either dorsally or ventrally, is likely to be uniformly yellow. 
Female: This sex appears to be uniformly larger than the 
male, there is more shining space on the face and front and not 
so much yellow on the abdomen, although the extent of this 
color is variable. 
Specimens from southern, central and northern Ohio. Previous 
authors have reported it from Colorado, Washington and Oregon. 
Myiolepta aurinota Hine. Male, length 9 millimeters. 
Antennae reddish, first two segments slightly darker and more 
shining than the third, third segment slightly narrower than 
long, arista colored nearly like the segment that bears it, slightly 
darkened toward the apex. Region surrounding the ocelli, space 
above the bases of the antennae, a triangular spot on the face, 
including the facial collositv, the oral margin adjacent to the 
facial spot and the cheeks shining black, remainder of front and 
face gray pollinose, with sparse white hairs near the eyes. Meso- 
notum including the scutellum entirely golden tomentose, plurae 
with white tomentum; wing nearly hyaline, slightly darkened on an¬ 
terior part more especially toward the apex; general color of the legs 
black with white hair, all the tibiae yellow at bases, first two 
segments of the middle and hind tarsi yellow, first two segments 
of each front tarsus dusky, but lighter colored than the three 
remaining segments, all the femora swollen and with short black 
spines below on apical parts, abdomen black clothed on the 
dorsum with black and golden vestiture, on sides with white 
vestiture; the black vestiture of the dorsum is very short and
