NO. 2115. NEW NEOTROPICAL MUSCOID FLIE8—T0WN8END. 409 



height; plane of parafacials projected obhquely forward; parafacials 

 fully two-fifths eye-width, quite evenly clothed with hairs scarcely 

 longer than those of parafrontals. Frontal bristles reaching only to 

 base of second antennal joint, the next to front bristle being exactly 

 opposite root of antennae. Arista short-plumose on the enlarged 

 basal half, the upper hairs slightly longer than the lower. One recli- 

 nate upper fronto-orbital in male. One pair of ocellars. Postverti- 

 cals nearly as long as ocellars. Inner verticals strong, outer verticals 

 weak and slightly or hardly differentiated from the occipito-orbital 

 fringe. Occipitocentrals more or less approximating the postverti- 

 cals in length. Front of male narrowed before vertex to width of 

 space between vibrissae, nearly twice as wide at base of antennae. 

 Epistoma practically cut off, only very slightly prominent or not at 

 all so, extending well below vibrissae. Length of head at vibrissal 

 angles about same as at root of antennae; facial profile a little shorter 

 than occipital, the frontal profile slightly sloping downward anteriorly. 

 Three sternopleurals and four postsuturals; one postacrostichal, two 

 or tliree preacrostichals; three dorsocentrals before suture. A discal 

 pair of scutellar bristles. A more or less developed marginal row of 

 short macrochaetae on tliird abdominal segment, marginal row of 

 fourth segment strong. Ventral plates two to four overlapping 

 lateral segmental sclerites. Ventral plate five cleft, the keellike 

 inferior edges of the two sections parallel and densely set with very 

 short spines. Claws of male extremely long. Third vein bristly 

 over halfway to small crossvein. ' 



PUNASARCOPHAGA AUROMACULATA, new species. 



Length of body, 7 to 9 mm. ; of wing, 6 to 8 mm. Six males, Oroya, 

 Peru, over 12,000 feet, Rio Mantaro valley bottom, March 7, 1913 

 (Townsend). 



Blackish, silvery pollinose, with gold maculation. Coloration plan 

 of the puna or high Andean sarcophagids, but with much less gold 

 than Dolichamohia auromaculata. Lacks entirely the pleural, coxal 

 and femoral gold spots; bears a large spot on each cheek, broad 

 lateral border- vitta of presutural mesoscutum extending to wing-root, 

 and spots on sides of abdominal segments one to four. Parafrontals 

 and parafacials wholly light golden in one continuous area. There 

 is a faint golden tinge to inside of median silvery pair of mesoscutal 

 vittae. The tergum of abdomen is marmorate silvery with faint 

 golden reflections and blackish median vitta. Venter golden only on 

 edges, rest obscurely silvery pollinose. Wing bases and tegulae dull 

 yellow. Hypopygium rufous, fifth segment golden. Two heavy 

 silvery-gray median vittae on thorax extending over scutellum, and 

 two narrower silvery ones outside them behind suture, leaving three
