Four examples from the following localities: Anping, July, 1911, 
June, 1912; Takao, May 3, 1907, and April 23, 1907.

Desmometopa tarsalis Loew, Beri. ent. Zeitschr., 1865, p. 184. 
Two examples of ' this species from the following localities : Takao, 
June 25, 1907, and Anping, April, 1912. 
Mallochiella lacteipennis Hendel. 
Madiza lacteipennis Hendel, Suppl. Entomol. Nr. 2, 1913, p. 108. 
A single male agreeing with Hendel’s description, Pilam, August, 1912. 
The description of the female only is given by Hendel. The male 
differs in having the hind femora swollen, and the hind tibiæ spatulate 
as in halteralis Coq. The legs do not show the annulations mentioned by 
Hendel as present on the mid and hind tarsi, though a close examination 
shows the first three joints to be reddish with brown apices. 
It may be well to mention that this species will fall into Desmometopa 
if regard is paid to the presence of the setulæ at the base of the wing, and 
the out curving of the two upper pairs of orbital bristles. In other respects, 
the shining frons and body particularly, the species is obviously more 
closely related to halteralis than to M-nigrum and its allies, so that it may 
well be retained in Mallochiella. 
Phyllomyza Fallen. 
The species herein described are congeneric with those placed by 
Melander in his genus Neophyllomyza. 1 The only character which serves 
to distinguish the present species from the type of Phyllomyza is, that, in 
the latter, there are four pairs of dorso-central bristles, whereas in the spe¬ 
cies in Neophyllomyza there are only two. In other respects the generic 
characters are the same, and the species may the more readily be retained 
in Phyllomyza as within the limits of the group of species placed in Neo- 
■jphyllomyza there are characters, in the structure of the head especially,
