 dominal pollen indistinctly spread but more dense basally on last three 

 segments. Wings clear. Tegulae glassy-white.

CHRYSOTACHINA PERUVUNA, new species. 



Length, 8 to 9 mm. Seven males and seven females; 11 from 

 Chosica, one each from Santa Eulalia, Lima, and Piura, Peru. (C. H. 

 T. Townsend.) 



Differs from Wiedemann's description of reinwardtii as follows: 

 Antennae largely smoky-rufous; second joint distinctly metallic gold- 

 green; third joint mostly brownish, twice as long as second in both 

 sexes. Head golden-yellow pollinose in both sexes, the parafrontalia 

 largely showing gold-green at least posteriorly. Frontalia light 

 brown. Abdomen, scuteUum, and thorax concolorous, usually gold- 

 green, but at times with bluish or pm-plish cast.

Clypeus flush. Epistoma wide, elongate, considerably warped. 

 Facialia bare. Proboscis about head height; palpi heavy, widened in 

 male, much swollen in female. Third antennal joint about two and 

 one-half times second. Arista nearly bare; basal joints short. Eyes 

 pilose. Frontals two to three below base of antennae. No pro- 

 clinate fronto-orbitals in male. Ocellars present. Paraf acialia bare. 

 Cheeks about one-third eye length. Two sternopleurals; three pos- 

 intraalars, postsuturals, preacrostichals, postacrostichals and lateral 

 scutellars. A weak decussate apical pair of scutellars. Third vein 

 bristled over halfway to small crossvein; other veins bare. Apical 

 cell open well before tip. Posterior crossvein nearer to cubitus. No
