Female specimens taken near Izabal, Gaatemala, March 7, 
1907. by D. D. Condit. 
Tabanus longiusculus n. sp. Length 11 to 13 millimeters. 
General aspect of T. longus but smaller and darker. 
Front or normal width, clothed with gfay dust, frontal cal¬ 
losity shining black, nearly square, a separated shining black 
area above it on the middle of the front; antennae yellowish 
brown with the annulate portion of the third segment black; 
third segment not especially wide at base, upper side with an 
angle near the middle of the length of the basal portion, but there 
is no process which rightly could be called a tooth; palpi white, 
thickened; proboscis a little longer than the palpi. Thorax 
dark with five gray stripes, not very plainly shown; wing hyaline 
with costal cell dilute yellowish; anterior legs, with the excep¬ 
tion of the bases of the tibiae, and bases of middle and posterior 
femora dark, almost black, remaining parts of legs reddish 
brown, although the tips of all the tarsi are more or less infus- 
cated. Abdomen with a rather narrow middorsal stripe and a 
row of rounded spots on either side; therefore each segment is 
dark in ground color with posterior border, a middle stripe and 
a spot on either side gray. Venter of the abdomen reddish 
brown at base and infuscated at the tip. 
Female specimens from Southern Pines, N. C., collected by 
A. H. Manee. Several females from Mimmsville, Georgia, re¬ 
ceived from C. S. Brimley, agree in detail with North Carolina 
specimens. 
Tabanus minusculus n. sp. Length 10 to 12 millimeters. A 
rather small dark colored species with the sides of the abdomen 
reddish brown and the eyes pilose. The wings have a slight 
brownish tinge, which is caused by a coloring of the margins 
of the veins. 
Female. Front normal in width, frontal callosity as wide 
as the front, black or dark brown in color, gradually narrowed 
above and reaching more than half way to the vertex, ocellig- 
erous tubercle present; first and second segments of the antennae 
brown, third segment brown at the base and black otherwise, 
distinctly wider than the second at the base and gradually nar- 
growed to the annulate portion so that no tooth is formed on the 
upper side although there is a slight prominence in place of a 
tooth. Palpi long and slender, brown in color. Thorax dark 
and striped above with narrow gray lines; wings hyaline, veins 
brown and narrowly margined with a brownish tinge, legs brown, 
varying toward black in a series of specimens, tarsi more or less 
infuscated. The abdomen above with a wide black stripe in the 
middle, interrupted by the narrow posterior margins of the seg¬ 
ments, each of which expands into a small triangle on the mid¬ 
dorsal line; sides brown, but in a series of specimens there is
