well-defined reddish brown lateral spots similar to the female ; median 

 stripe and dull orange yellow segmentations much narrower than in 



the female; pubescence as in the female, but usually longer and about 



' 

 the sides of all the segments almost black except on the first segment 



there is some paler one intermixed. Belly much more pubescent than 

 in the female. 



Length : 12.3-13 mm. 



Described the above from a series of males and females, of 

 which a female from Shinano (July nth., 1918) is much more yellow- 

 ish at the abdomen and legs and bears yellowish pubescence on the 

 disc of the thorax. 



This species in appearance is very closely allied to Tabanus 

 fulvimedius, Walker, but easily distinguished from that, by the quite 

 separated frontal calli on the broader frontal stripe, by the post-ocular 

 bare rim contracting above, by the clear wings, by the narrower abdo- 

 minal stripe, and by the underside of abdomen all black ; there is no 



other allied species at least in the palaearctic and oriental regions. 



. 



At the present time, T. fulvimedioides is one of rather common 

 species in the southern parts of Japan, as I have records from Tokio 

 (June), lyo (June 4th.), Kumamoto (April 2Oth.), Shinano (July nth. 

 1918), Miyazaki (August 4th.), Miyachi (July 2nd.), Shimabara (June 

 29th.), Fukuoka (July lOth.), and Ichibu (July 3rd.) ; in the latter district, 

 I collected many females which are resting on the belly of horses 

 near the village of Menda (Kumamoto-Ken), from this fact it may be 

 evident that it is a biting fly.
