FORMOSAN AGROMYZIDAE. 309 



Rhicnoessa sexseriata Hendel. 



Rhicnoesm sexaeriata Hexdkl. id.. ]). MO. 



Four examples from the following localities: Anping, July, 1911, 

 June, 1912; Takao, May 3, 1907, and April 23, 1907. 



Desmometopa tarsalis Loew. 



Desmomelopd (<irmlif< LoEW, Bcrl. cut. Zcitschr., ISdf), i>. 184. 



Two examples of this species from the following localities: Takao, 

 June 25, 1907, and Anping, Aprd. 1912. 



Mallochiella lacteipennis Hendel. 



Mudiza ludeiptnnin Hendel, ^Supj)!. Entomol. Nr. 2, 1013, p. 108. 



A single male agreeing with Hendel's description, Pilam, August, 1912. 



The description of the female only is given l:)y Hendel. The male 

 differs in having the hind femora swollen, and the hind tibise 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 hito Desmometoixi 

 if regard is paid to the presence of the setulse at the base of the wing, and 

 the outcurving of the two upper pairs of orbital bristles. In other respeats, 

 the shining frons and l)ody particularly, the species is obviously more 

 closely related to halteralis than to M-mqmm and its allies, so that it may 

 well be retained in MallocliieJla. 



Phyllomyza Fallen. 



The species herein described are congeneric with those placed by 

 Melander in his genus Neofhyllomyza^ The only character which serves 

 to distinguish the present species from the type of Phyllomyza is, that, m 

 the latter, there are four pairs of dorso-central bristles, whereas in the spe- 

 cies in Neoyhyllomyza 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- 

 j}hyllomyza there are characters, in the structure of the head especially,
