Female specimens taken near Izabal, Guatemala, 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 gray 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-

 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 Avide 

 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-

 dorsal line; sides brown, but in a series of specimens there is-
