writer hesitated to describe this variant because of its like- 
ly extension into Mexico and the possible application of an 
earlier name. Lack of adequate Mexican material gives no 
assurance that this is not the case, but the form is distinct 
from any Neotropical material studied by me or by Fair- 
child. 
Discovery of the correct male of vittiger is needed to jus- 
tify assignment of nippontucki as a subspecies. The fronts 
of the females and femoral colors are in agreement, but the 
wider, all reddish antennae, whitish hind tibial fringe, and 
different abdominal pattern with wide middorsal stripe 
(widened on the incisures somewhat as in may a Beq. and 
some other Neotropical species) may set this apart as more 
complete information is forthcoming. These remarks apply 
equally to differentiation from guatemalanus Hine which 
Fairchild also associates with vittiger. 
T. amplifrons Krober. The female from Brownsville, 
Texas, assigned to T. truquii Bell, by Stone (1938) has the 
parallel-sided front, small yellowish callosity, dark scutel- 
lum, reddish femora, and other characters of Krober’s spe- 
cies, as well as of Hine’s (1906) Guatemala truquii, and cer- 
tain other Neotropical specimens recognized by Fairchild. 
The associated males from Brownsville, Uvalde, and Gal- 
veston have hairy eyes with fairly uniform facets, but they 
show the peculiar contrast to the females of dark femora 
and somewhat enlarged scapes of Bequaert’s (1940b) T. 
trilineatus and Hine’s T. truquii. These sex differences are 
not in accord with other species of the lineola complex. 
I have also seen a confusing series of males from Gal- 
veston which differ only in having uniformly reddish legs 
and small antennal scapes. Whether these belong here or 
are a different variant is uncertain at present. 
There appears also a good possibility that an earlier name 
from among the now unplaced Neotropical ones eventually 
may be found to apply. 
Separation of amplifrons, scutellaris, schwardti, and 
nippontucki still leaves a somewhat heterogeneous group of 
flies in lineola s. lat. which are susceptible of only unsatis- 
factory analysis in the absence (1) of unquestioned asso- 
ciation of males with divergent females, (2) of the real
