Numerous specimens, some without, some with, aeneous to purplish 

 reflections. Basal three segments or antenna often wholly pale, the 

 basal y2-% of the third segment sometimes, all of 4 but the extreme 

 base, and the apical half or more of 5, dark. Legs chiefly testaceous. 

 Puncturing is much as in hurmeisteri, there being a few rows in trans- 

 verse band on pronotum, noticeable groups of punctures near lateral 

 margins, and rather more evident along margins and in ends of ante- 

 rior lunate area of scutellum, than in the more laevigate species. 

 Dorsal view of male hypopygioim as in figure 33; ventral view of 

 female genitalia as in figure 37. Length 5-6 mm. 



In this and the next succeeding species the scutellum is rather 

 rugulose posteriorly, the punctures in the furrows, a character in 

 which they differ from all the other species treated in this paper. 



There are four specimens in the Universitetets Zoologiske Museum, 

 Copenhagen, labeled " Amer. mer. mus. Schmidt, Dom. Sehestedt," 

 of which the first, a female, is regarded as the holotype ; of the other 

 specimens, one is a female and two are males; there are also two 

 specimens labeled " S. America, Mus. Westermann," which are cor- 

 rectly placed; at Kiel (Zool. Mus. Univ.) there are two females 

 labeled Brazil, one bearing the determination impressus in Fabricius' 

 handwriting; other specimens examined are from Maroni River, 

 French Guiana, William Schaus; Para, and Amazonas, Brazil; 

 Cachuela Esperanza, Beni, Bolivia, March, 1922, W. M. Mann ; Tumu- 

 pasa, Bolivia, December, M. R. Lopez (U.S.N.M.) ; Santarem, 

 Brazil, July, 1919, and undated, S. M. Klages ; Mana River, French
