practical identical with T. okinawanus, but in minor point differs from 

 that as follows : 



Antennae yellowish-red to reddish brown or blackish ; the stripes 

 on the thorax in some specimens very faint ; the median interrupted 

 black stripe in a few specimens rather broad ; the wings more smoky 

 but in the cells rather distinct narrow hyaline spots which sometimes 

 disappear in the posterior cells. 



T. okinawanus is only a recognized species in the Island of 

 Oshima up to the present, and the female appears very abundant on 

 the road through a pine-tree forest on a drizzly day, and also flies into 

 houses built in a mountainous district in the evening, or sometimes it 

 is attracted by light at night. The bite of the female was only a two 

 day's matter to me, but I felt a very painful needle-puncture during 

 the first day. This species may be not uncommon in Okinawa in July 

 or June. The male is not known to us.

A reddish brown medium-sized species with the narrow and 

 long frontal callus (with a very long linear extension) on the narrow 

 frontal stripe, with the very faint greyish stripes on the greyish brown 

 thorax, with the rather small and narrow yellowish-haired triangular 

 median spots on the reddish brown abdomen, and with the basal half 

 of the front tibiae of the female distinctly pale yellowish white 



Female, Head slightly wider than the thorax, about two-fifths 

 as long as the thorax, moderately arched. Frontal stripe covered with 

 brownish grey tomentum which becomes paler below and above, and 

 with numerous short sloping black pubescence which is quite absent 

 on the lower fourth and becomes slightly longer and more erect on
