HaUtat— Japan. Holotype, d" , Saitama, May 29, 1919, (R. 

 Takahashi) . 



The present species bears a strong superficial resemblance to 

 D. suhmorio, but the venation and male hypopygium are very 

 distinct. 



Gemis THRYPTICOMYIA Skuse 

 Thrypticomyia arcuata new species 



Antennae dark brownish black; thoracic dorsum pale brown without 

 stripes, the pleura yellow; halteres black, the basal half of the stem yellow; 

 legs with the tarsi white, except the extreme bases of the metatarsi; wings 

 hyaline with conspicuous black veins, the wing-tip indistinctly darkened; 

 inner end of cell 1st Mi arcuated, in a line with the inner end of cell Rz. 



Male. — Length, about 5.5 mm.; wing, 6 mm. 



Rostrum orange-yellow; palpi with the basal segment yellow, the terminal 

 segments dark brown. Antennae rather long for this genus, dark brownish 

 black, the scapal segments a little paler; flagellar segments long-oval with

 the metatarsi and the claws brown. Wings hyaline with the veins very 

 conspicuous, black; stigma oval, brown; tip of the wing very indistinctly 

 darkened. Venation: Sci ending just beyond the origin of ii*.s, Sc^ r:ither 

 far from its tip, aSci being a little longer than the basal deflection of Cui; 

 basal deflections of Ri-\- 5 and ikf 1+ 2 strongly arcuated, so the inner ends of cells 

 Ri and 1st Mi are about on a level and far proximad of the inner end of cell 

 R^; basal deflection of Cui beyond mid-length of the long cell 1st Mi. 



Abdomen elongate, the tergites dark brown, the sternites paler brown. 



Habitat.— Japan. Holotype, d', Tokio, May 9, 1919, (R.
