J. R. MALLOCH. 
27. Agromyza nigrisquama n. sp. 
This species is very similar to the above, but differs in being com¬ 
paratively larger, 2*5 '2*75 mm, the wings are more elongated, with the 
cross veins more consistently approximated, the cheek about one-third 
the height of the eye, and in its more robust form. 
Type: Tainan, April, 1912. 
Paratypes: Tainan, Takao, and Chip-Chip. Twenty-two specimens. 
OCHTHIPHILINAE. 
Leucopis apicalis n. sp. 
Male: Black, densely covered with silvery pollen. Frons brownish, 
covered with silvery pollen ; antennæ and arista yellow, the latter darkened 
apically, and the former brownish at base; palpi browm-black ; proboscis 
yellow at apex. Mesonotum in too poor a condition in specimens to say de¬ 
finitely if striped, but from the fact that the setulæ are arranged in rows 
I infer that it should have at least distinguishable vittæ. Basal segment 
of abdomen without spots, second and succeeding segments with a narrow 
median and very small lateral black spots. Legs yellow, coxae brownish, 
femora, except bases and apices, black, middle of all tibiae brownish, apical 
tarsal joint on all legs brown. Wings milk-white, veins almost colorless. 
Frons one-third the width of head ; antennæ of moderate size, third 
joint as long as broad, upper apical margin slightly angulate, lower apical 
margin rounded ; arista not longer than anterior width of frons, basal joints 
elongated, occupying one-third of the entire length, swollen; cheek barely 
one third the height of eye. Mesonotum with normal hairing. Hypopygium 
rather large and knob-like. Legs strong, without bristles. Inner cross vein 
at beyond the end of first vein and slightly less than one-third from apex 
of discal cell; last section of fourth vein about 5 times as long as penulti¬ 
mate section ; veins 3 and 4 convergent at apices ; last section <5f fifth vein 
1 y 2 times as long as outer cross vein. 
Length: 2—2*5 mm. 
Type: Tainan, February. 
Paratype: Same data. 
Female : Similar to the male in color and structure except that the 
ovipositor is inconspicuous, and the inner cross vein is situated nearer to 
the middle of the discal cell. 
Allotype: Same data as type.
