specimen in the Kiel collection is fragmentary, consisting of wings, 
fore legs, part of thorax and first two abdominal segments almost 
completely denuded. Specimen bears an old label with “lineola” on 
one side and “49” on the other. The wings are glass clear, the 
costal cell not tinted and without appendix on third vein. Fore 
coxae pale grey pollinose, white haired; femora black, pale haired; 
tibiae with basal half white, apical half and tarsi black. "I horax 
blackish with notopleural lobes reddish, as are sides of mesonotum. 
Scutellum destroyed by pests. First abdominal tergite yellow with 
a pair of small round submedian dark integumental spots nearly 
touching in mid-line. Between them there are the remains of a 
whitish pollinose streak. Second tergite with a broad median dark 
stripe which is somewhat forked at its posterior end and fails to 
reach hind margin. This median dark integumental stripe is over- 
laid by vestiges of a narrow pale pollinose stripe. Nothing in the 
type contradicts present assignment of the name to the Nearctic form, 
though absence of scutellum prevents certainty that it is not sub- 
similis Bell. Wholly clear wings rule out Neotropical forms except 
colombensis Macq., which has darker and less contrastingly marked 
tergites. Use of this name by Krober (1932) for southern Neotrop- 
ical material is unwarranted. The Bose specimen, not found in Paris, 
is probably lost. 
Tabanus pellucidus Fab. 1805, Syst. Antliat., p. 97, America meri- 
dionali Dom. Smidt. Mus. Dom. de Sehestedt. The type (C) bears 
an old label with “T. pellucidus ex Am: Mer: Schmidt”. It is on 
an old short pin, is extensively denuded, lacks antennae, mouth parts, 
palpi, and all legs; hole in subcallus and base of abdomen beneath. 
The beard and fore coxae white. Abdomen above reddish with traces 
of white sublateral patches, beneath with broad sublateral white- 
haired longitudinal bands. Wing veins brown-margined, first pos- 
terior cell closed and petiolate. It agreed closely with a homotype 
of T. senior Wlk. in shape of frons and all else remaining, except 
that wing cell closed further from margin. Another specimen (K.) 
not labelled type, lacks head, legs and one wing and is very dirty 
and denuded. In this the cell is open, but the specimen too fragmen- 
tary for certain placement. I believe the following names, whose 
types I have seen, to be synonymous as noted elsewhere (Fairchild 
1966a in press). T. crassicornis Wied. 1821, T. albibarbis Wied. 
1824, T'. angustifrons Macq. 1847, T. alboater Wlk. 1850, T. senior 
Wlk. 1850, T. atricornis Big. 1892, and probably also Chelommia 
amazonensis Barr, 1949, of which I have not seen the type. The 
species is variable as to color, brown to black, and the first posterior
