78 TABANUS EQUESTRIS. 



Ent. XI. 100. 3), the name of which, having been used 

 before, is changed by Osten Sacken in T. van der Wulpi 

 (Berl. Ent. Zeitschr. XXVI. 97); it differs, however, by 

 its fulvous posterior legs, its more slender antennae, the 

 third joint of which is darker, and by the pattern of the 

 wings, showing, in stead of two crossbands, but a single 

 one which passes over the discal cell.
