252 NORTH AMERICAN ANTHOMYIID FLIES OF GENUS PHAONIA 



Eyes long haired; narrowest part of frons as wide as distance across posterior 

 ocelli; orbits setulose to above middle; parafacial as wide as third antennal 

 segment, not narrowed below; face receding below; cheek twice as high as 

 width of parafacial, with several series of marginal bristles; third antennal 

 segment about 1.5 as long as second, its apex about one-fourth from mouth- 

 margin; arista short haired. Presutural acrostichals not differentiated; 

 postsutural dorso-centrals three; prealar long and strong; hypopleura with 

 some hairs on upper margin in front of spiracle. Abdomen short ovate, 

 basal sternite bare, fifth with a broad rounded posterior excision, rather 

 densely hairy on sides apically, without strong bristles. Fore tibia without 

 tong hairs or bristles; fore tarsus slender, exceeding length of tibia; mid legs 

 lacking in type; hind femur with a complete series of bristles on anteroventral 

 surface, which are weaker basally, and a series on basal half of posteroventral 

 surface; hind tibia with two anterodorsal, and two anteroventral bristles. 

 Outer cross- vein curved; last section of fourth vein twice as long as preceding 

 section. 



Length, 6 mm. 



Type. — Lunenburg, Massachusetts, May 19, 1916, (S. M. 

 Dohanian), [U. S. N. M.]. 



Apparently closely related to confluens Stein, of Europe. 

 I have not seen this species but the arista is described as long 

 haired and the hind tibia more bristly. 



Fhaonia tipulivora new species 



Male. — Black, slightly shining, densel}^ grayish pruinescent. Frons para- 

 facials, face, and cheeks almost silvery; antennae and palpi black. Thorax 

 with four black vittae. Abdomen with a series of poorly defined but distinct 

 black subtriangular spots and, when seen from the side, with some lateral 

 black checkerings. Legs black, tibiae brownish. Calyptrae white. Halteres 

 yellow. 



Eyes densely hairy; narrowest part of frons about as wide as distance 

 across posterior ocelli; interfrontalia almost obliterated above middle; orljits 

 setulose nearly to anterior ocellus; parafacial as wide as third antennal segment, 

 not appreciably narrowed below; cheek nearly twice as high as width of 

 parafacial, with several series of bristles on lower margin; third antennal 

 segment about L75 as long as second; arista with its longest hairs not as long 

 as width of third antennal segment; palpi normal, setulose. Thorax without 

 differentiated presutural acrostichal bristles; postsutural dorsocentrals four; 

 prealar very long; hypopleura hairy on upper margin in front of spiracle; 

 sternoplcurals 1 : 2. Basal abdominal sternite bare, fifth as in fratcrna; 

 abdomen broadly ovate. Fore tibia with two cr three posterior median 

 bristles; fore tarsus slender, dislmctly longer than tibia, with a few long 

 sensory hairs along the posteroventral margin; mid fcnnu" with about six 

 bristles on basal half of posteroventral surface; niitl til)ia with six or seven 

 bristles in a double scries on ])osterior side; hind femur with a comi)leto scries
