PUNAPHYTO, new genus. 



Genotype. — PunapJiyto tridens:, new species. 



Differs from (S'arcot^exm as follows : Male only described. Front at 

 vertex a little wider than eye, widening very slightly anteriorly, face 

 widening very slightly from same. Frontalia occupying ahnost or 

 quite one-half of frontal width. Two small proclinate outer fronto- 

 orbitals in male. Heavy strong almost exactl}^ divaricate ocellar 

 pair. Row of fine hairs extending from parafrontals over parafacials 

 to cheeks. Four or five facio-orbitals in close row near lower border 

 of eyes and in line with the fine hair row, the lower two or three 

 strong. Arista very short-hairy on a little over the basal half. 

 Proboscis below geniculation about as long as antennae, stout, thick, 

 corneous, hardly more than four times as long as thick, rather pointed 

 at tip, the labeUa small. Front is rather prominent, the length of 

 head at antennae about equal to length at vibrissae. Occiput bulged 

 in middle inferiorly. No acrostichals. Two dorsocentrals before 

 suture. Three postsuturals and three sternopleurals. Posterior 

 lateral pair of scutellars nearly reaching base of anal segment. Long 

 costal spine. First vein bristly whole length, third vein bristly to 

 small crossvein. Apical crossvein strongly bent in at base. Claws 

 of male only a little elongated, about as long as the last tarsal joint. 



PUNAPHYTO TRIDENS, new species. 



Length of body, 4 to 6 mm.; of wing, 3 to 4.5 mm. Four males, 

 Oroya, Peru, over 12,000 feet, valley of the Rio Mantaro, May 7, 

 1914 (Townsend). 



Black, brassy-cinereous pollinose. The black parts include palpi 

 antennae, frontalia; three strong broad equal vittae on thorax, the 

 middle one continued over scutellum; a lateral stripe extending from 

 point a httle in front of suture to sides of scutellmn, broad stripe 

 from humerus to wing-root, sternopleural and hypoploural regions; 

 thi'ee vittae on abdomen, confluent along hind margins of all the seg- 

 ments; and the legs. The head poUen is but faintly brassy, that of 

 thorax a httle more so, that of abdomen rather cupreous than brassy. 

 Wings clear except faintly smoky-yellow costobasal area. Tegulae 

 nearly white, tawny-yellowish on borders.
