J. R. MALLOCH. 
bristle moderately strong; hind femur with a rather irregular row of short 
bristles from base on antero-ventral surface, the three on apical third strong, 
subequal; the postero-ventral surface with a row of longer, hair-like bristles, 
which are of moderate length at base, and slightly increase to apical 
third, where the row ceases; hind tibia with 2 dorsal, 1 antero-dorsal, and 
1 antero-ventral bristles, above the antero-dorsal bristle there is a series of 
short setulæ; tarsi normal. Wings with last section of fourth vein almost 
three times as long as the penultimate section; outer cross vein slightly 
waved, situated at about half its own length from apex of fifth. Under 
scale of calyptræ very much larger than the upper. 
Length: 8*25 mm. 
Locality: Takao, Formosa, April 18, 1907 (Sauter). One male (Mus. 
Hung.). 
This species is most closely allied to F. Howardi Mallo ch, which 
may be distinguished from the above by the very different bristling of 
the hind femur, which has the postero-ventral row carried to nearer the 
apex, and the last 8—4 hairs very long and curled. In leucosticta Me igen, 
the calyptræ are whitish, and also smaller and more equal in size.
