on the fourth the black is more extensive, and on the fifth there may be some reddish 

 as well as the lateral margins. 



Tabanus cinctus Fabricius. 



This species is common in Connecticut, and is very conspicuous by reason of the 

 bright yellow basal part of the abdomen. Baron Osten Sacken rather incorrectly 

 describes the color as yellowish red. 



Tabanus Reinwabdtii Wiedemann. — Western Kansas. 



Tabanus Megeelei "Wiedemann. 



The possession of two specimens of this species in good condition, from Florida, 

 enables me to give a more complete description, as follows: 



Female: Length 17-20 mm. Antennae deep red, the annulate portion of third 

 joint blackish, the angle of the third joint produced into a long slender process. 

 Face yellowish brown, with brown pile. Front brown, below the callosity yellowish 

 white, of nearly equal width; callosity nearly black, scarcely higher than broad. 

 Palpi yellowish, clothed with black hairs, giving them a brownish appearance. A 

 patch of black pile at the denuded vertex. Eyes distinctly pubescent. Dorsum of 

 thorax brownish-black, reddish on the sides, with fulvous pubescence and indistinct 

 grayish stripes. Pleurje black, somewhat reddish in the middle, with black pile. 

 Abdomen yellowish red; a broad black stripe, obscurely narrowed on the second and 

 third segments, the lateral margins also black; the fulvous portion has fulvous 

 pubescence in front, whitish pubescence and pollen behind. Venter yellowish and 

 brownish red, with abundant silvery pollen and pile. Legs dark reddish brown, the 

 femora more blackish. Wings brown on the proximal jjart, the cross-veins and 

 furcation of third vein with dark-brown clouds. 



Tabanus insuetus Osten Sacken. 



A single specimen from North Park, Colorado, agrees so closely with the descrip- 

 tion of this species, that I have little or no doubt of the identity, notwithstanding 

 the difference in locality. 



B. Eyes bare, Tabanus. 



Tabanus turbidus Wiedemann. 



A female specimen from Alabama is evidently of this species, but the angle of 

 the third antennal joint is distinctly drawn out into a point. 



Tabanus fkonto Osten Sacken. 



A female from Florida, evidently of this species, is nineteen millimeters in length, 

 the abdomen is largely blackish posteriorly, and the first posterior cell is closed. 



Tabanus abdominalis Fabricius. 

 Tabanus exul Osten Sacken. 



Specimens of the above two species from Kentucky and Virginia leave no doubt 

 of the propriety in separating them on the frontal width and the open first posterior 

 cell. 



Tabanus suLCiruoNS Macquart {tectus O. S.) 



Two specimens from Louisiana agree with the ones described by Osten Sacken 

 from Texas in having the abdomen flattened, and with a white spot on the sixth 

 segment. One of them measures only 15 mm. 



Tabanus beoedens Walker {T.calenatus 0. S. non Walker.) 



Although it is a sad commentary on justice to recognize or give preference to 

 Walker's name, yet I do not think it feasible to retain the name T. catenatus O. S.,
