Musidora orientalis n. sp. cf $ . 
Head shining yellow, face whitish-yellow, the spot of the ocelli dark¬ 
ened. Antennæ yellow, arista blackish-brown. The bristles on the vertex, 
jowls and peristome and the cilia on the margins of the eyes yellow, the 
orbital and ocellar bristles somewhat brownish. 
Thorax yellow to reddish-yellow, chill (owing to dust) with two indis¬ 
tinct narrow stripes in the line of the dorsocentral bristles beginning behind 
the suture only, and not reaching the scutellum; above the notopleural 
suture likewise a brown stripe, dilated in front, and black just before the 
basis of the wings. Scutellum quite yellow. The bristles of the thorax as 
well as those on the scutellum yellow. Pleuræ pale yellow, faintly shining. 
Abdomen brownish to blackish-brown, a little shining. Hypopygium 
of the male yellow to brownish, complicated and very difficult to describe, 
therefore I prefer to give a sketch of it. 
The posterior gonapophyses (jpg) curved, 
dilated below and becoming smaller to¬ 
wards the apical part ; the anterior ones 
(ag) long, stick-like, bearing a strong 
and long bristle on the tip and in the 
apical third on the inner side two similar 
ones, the upper of which is longer than 
the inferior one. The penis armour can not 
be seen very well, but the small plate lying 
over it is very characteristic, bearing two 
long bristles on the upper part and two 
short ones on the sides. 
Legs pale yellowish, the last four joints 
of the tarsi more or less darkened. Front 
femora with two bristles on the upper side 
before the tip. On the middle- and hind tibiæ 
two bristles on the front and one behind, 
the last-named shorter than the other two. 
Wings uniformly yellowish, the veins of the same colour. The anal 
vein ends somewhat before or opposite to the fork of the fourth longitudinal 
vein. Halteres yellowish to brownish-yellow. 
The females are very similar to the males, but their colour is always 
darker and the wings are not so intensively yellow. All bristles are brownish, 
but those on the vertex and the cilia on the margins of the eyes always yellow. 
Lenght 8*2 mm, wings 4*1 mm. 
Three males and four females from Formosa caught by Mr. H. Sauter 
at Chip Chip (I. III. 1909), Kosempo (XI. 1908) and Pilam (XII. 1908).
