The two species known to me may be separated as below. 



Frons testaceous, with a complete, narrow, ceutral brown vitta ; a pale brown 

 mark between each antenna and eye, which is longer tlian height of third 

 antennal segment, and a br«wn mark below each antenna ; lower margin of 

 cheek with a rather long bristle about middle, and in front of it numerous 

 short black haii-s on entire cheek, which extend above lower level of eye. 



hirticeps, new species. 



Frons testaceous, with a small fuscous mark on occUar region ; a round choco- 

 late-brown, or black, mark between each antenna and eye, and a similarly 

 colored mark on parafacial suture below each antenna ; cheek with three or 

 four long bristles on lower margin, the foremost one at, or close to, lower level 

 of eye, and in front of it two or three fine hairs, none of them on disk of the 

 cheek facialis, now species. 



MAQUILINGIA HIRTICEPS, new species 



Female. — Yellowish testaceous, slightly shining. Head as de- 

 scribed in key. Thorax with two brown vittae along inner margins 

 of the series of dorsocentrals, which are continued over the scutellum, 

 a paler vitta on each side of these behind suture, and a fainter com- 

 plete one between it and lateral margin, a pale yellow line on exact 

 center of mesonotum and scutellum. Abdominal tergites narrowly 

 dark brown on apices. "Wings grayish hyaline. Halteres yellow. 



Frons about 1.5 as long as wide at center, quite copiously black 

 haired in front of ocelli, anterior orbitals a little incurved at tips, 

 about two-thirds as long as posterior pair, and about as long as width 

 of third antennal segment; arista with very short pubescence; face 

 slightly receding below; eye about 1.25 as long as high; cheek at 

 bristle about one-third as high as eye. Thorax with 1 + 2 pairs of 

 long dorsocentrals, four series of intradorsocentral hairs, a pair of 

 prescutellar acrostichals, and the posthumeral, and anterior sterno- 

 pleural, short. Abdomen tapered apically. Legs normal, the fore 

 tarsi slightly dilated apically. Inner cross vein close to middle of 

 discal cell, penultimate section of fourth vein a little less than half 

 as long as ultimate section; first posterior cell slightly narrowed 

 apically. 



Length, 3 mm. 



Type.—Q2it. No. 41599, U.S.N.M.; Mount Maquiling, Luzon (C. F. 

 Baker). 



MAQUILINGIA FACIALIS, new species 



Female. — In addition to tlie distinguishing characters listed in the 

 key this species differs from hivtlceps in having the frons shorter, 

 about 1.25 as long as wide, and less copiously haired, the orbital 

 bristles longer, the anterior pair being at least 1.5 as long as width 

 of third antennal segment, the eye is more rounded and but little 

 longer than high, the cheek is about one-fourth as high as eye at
