Both my females belong to the var. versicolor, they have only two bristles on hind tibiæ, while both my males have three. I have seen Zetter- stedt's types to Trineiira palpina; I saw four females labelled "Espe- rød"; they are identical with florea. Geographical distribution: — Probably all Europe and known from North Africa; towards the north to southern Sweden. Remarks: The two species abdominalis and florea since Becker's monograph have been considered as only one species with the spec- imens with three hind tibial bristles as a var. flexuosa, but in 1920 Schmitz proved with certainty that they are two well distinguished species. The male of abdominalis has been thought to have sometimes a red abdomen like the female and is mentioned thus both by Becker, Wood and Schmitz in 1918; this is evidently caused by Schiner who stated that he had seen the male, and it had a red abdomen, but as Schmitz in 1920 says this is no doubt erroneous, Schiner had certainly only the female. Schmitz 1. c. refers sororcula v. d. Wulp as a synonym to florea, but he has later on communicated to me that this, according to a letter from de Meijere, is an error, sororcula being identical with abdominalis.
