One male from Edwards' type-locality, Horisha, 1916, No. 

 1332. One male, Shinchiku, Formosa, July 1-30, 1918 (J. 

 Sonan and K. Miyake). Riedel describes the legs of his species 

 as being "powerful," but in spite of this discrepancy, there 

 can be no reasonable doubt of the synonymy.

 No. 1327. This series of specimens agrees well with Edwards' 

 characterization of the type. The additional details of structure 

 of the hitherto unknown male may be given. 



Allotype, cf. Very similar to the female, differing only in the 

 sexual characters. The antennas are short. Hypopygium with the 

 ninth tergite large, nearly quadrate, with a conspicuous, flattened 

 median lobe that is deeply notched medially, the lateral lobules thus 

 formed being compressed blades that are covered with abundant black 

 spicules. Outer pleural appendage large, flattened, broad basally, 

 gradually narrowed to the rounded apex, pale yellowish white and very 

 conspicuous. From the ventral-caudal angle of the ninth pleurite, 

 close to the ninth sternite, two conical appendages hang in the notch 

 of the ninth sternite, these provided with a pencil of long, reddish 

 bristles at their tips. Ninth sternite strongly carinate. Eighth 

 sternite somewhat projecting, the median area unarmed, on either side 

 of the median area with a dense fringe of moderately long silvery 

 bristles. 



Male — Length 17-lS mm.; wing, 20-24 mm.
