with dull yellowish apical ambulation, and in the intensity of the cross- 

 band which includes the antennae ; other minor variations in the colour 

 of the pubescence, or of the legs or abdomen, are noted in the des- 

 cription, but the variation in the amount of the black bristles on the 

 palpi of the female is remarkable, as it may extend from entire absence 

 to nearly exclusive predominance. 



T. cordiger appears to be an uncommon species in Japan, and 

 1 have but little knowledge of it. It may occur, however, in the north-

 records from Akita and Kumamoto, where a series of the materials I 

 described have been collected by me. It has been recorded from 

 Europe and North Africa, and is common in South Europe along the 

 Mediterranean to Asia Minor, but northwards it becomes less common 

 though it extends to Finland or England. 



I have no actual knowledge of the economic statement of this 

 Tabanus, but it may attack horses or cattle, as labamis do usually.
