ones on the second and third pair, and the tibiæ of the third are dark 
brown. The quills yellow, their tip black. 
Length: 2—2*5 mm; wings: 0*09—0*12 mm. 
One male and seven females from Formosa, Takao and Tainan caught 
by Mr. H. Sauter. 
This genus and species are so easily recognised that, a comparison 
with the above description and figure, should prevent any mistake. 
But is is of great importance to fix the systematic position of the 
genus. 
The exceedingly reduced wings and the equally reduced chætotaxy 
of the head are stumbling blocks. The Hungarian National Museum 
possesses a winged species belonging to a new genus (Sepsidoscinis Hendel 
in litt.) also from Formosa, the head of which is rather similar and the 
tergites also coalescent. A paper about it by Mr. Hendel will soon be 
published. 
Similar quill-like bristles are found only in Anatrichus erinaceus Lw. 
with which it agrees, in having the last tergites completely coalescent, 
and the sternit es similarly so. 
The large, strongly developed frontal triangle, the reduced chæto¬ 
taxy of the head, pleuræ, and legs, a development of the abdomen similar 
to that of Sepsidoscinis and Anatrichus, as well as the abnormal bristling 
of the upper side common with the latter genus, makes it a member of the 
Oscinellinæ. In this sub-family, short vibrissæ and strongly developed 
bristles on the vertex are not rare. 
I am very much obliged to Mr. F. Hendel wo has been kind enough 
to make the drawing of the fly.
