PHOBETICOMYIA LUNIFERA (de Meijere) 



Phoheticomyia hmifera de Meijere, Tijdscbr v. Bnt., vol. 53, p. 134, 191C 

 {iLatixania) . 

 Frey records this species from Port Bauga, Mindanao. 



PHOBETICOMYIA PREAPICALIS, new species 



In addition to the wing markings being distinct this species differs 

 from hmifera in having the face glossy black, with a faint central 

 vertical yellow stripe. In lunifera the face is glossy black, with the 

 entire lower margin, and a broad V-shaped mark on middle, yellow. 



Length, 3.5 mm. 



Type^ male, and one pm'atype^ both lacking the third antennal seg- 

 ment, Singapore (C. F. Baker). In author's collection. 



Genus TRYPAN'EOIDES Tonnoir and Malloch 



This genus is distinguished from all others except Melinomyia 

 Kertesz by the presence of two strong bristles on the mesopleura, 

 one on upper hind margin, and the other, which is directed down- 

 ward, close to middle of disk (the latter sometimes duplicated). 

 From Melinomyia it may be distinguished by the presence of two 

 aternopleurals, and the conspicuously marked wings. The costa is 

 the same as in Homoneura,, both orbitals are bent backward, the 

 thorax has 1 + 3 strong pairs of dorsocentral and acrostichal bristles, 

 the abdomen has sparse erect setulose hairs, and at apices of all 

 tergites quite conspicuous bristles; there is always at least one con- 

 spicuous bristle a little beyond middle of anteroventral surface of 

 hind femur; the intra-alar bristle is weak or absent; and the fore 

 femur has no anteroventral comb. 



The genotype, guttata Tonnoir and Malloch, is found in New 

 Zealand. Below I present a key to the Oriental species known to me. 



KEY TO THE SPECIES 



1. Abdomen glossy black, entirely without markings ; three clear spots on 



costa of wing between apices of first and second veins; arista rather 



long haired 2. 



Abdomen brownish or fuscous, with conspicuous gray-dusted spots or mark- 

 ings, and sometimes with brown spots ; at least four clear spots on costa 

 between apices of first and second veins 6. 



2. Wing with at least two complete clear fasciae in addition to some isolated 



clear spots 3. 



Wing without uninterrupted clear fasciae, sometimes with transverse series 

 of clear spots 5. 



3. Wing with two clear fasciae, one just proximad of inner cross vein, and 



sometimes narrowly enclosing it, and the other at about its own width 

 beyond outer cross vein, terminating on costa before apex of second vein, 

 the clear mark on costa between the fasciae not extending over second 



vein bicincta (de Meijere) . 



AVing with three complete clear fasciae, the third one extending across the 

 wing from apex of second vein, between the second one and the apical 

 clear spot 4.
