than second, rounded at the hind margin, fourth tergite again much 

 narrower, quite small, about quadratic. The female may also have 

 a quite black abdomen, the form with only the tergal piates black, 

 the rest red Schmitz describes d. c. 1920) as var. versicolor. 



Fig. 61. Wing of D. florea $. 



Length 2,8—3,7 mm. 



Also D. florea is rare in Denmark, we have only four specimens, 

 two males and two females; Frederiksborg, an old male specimen 

 (Fr, Jacobsen), Sorø Sø, a male, and at Hejls south of Kolding on 

 ^^/v and ^V? 1919 (the author), two females, one of them from under 

 a dead crow; the specimen from Sorø Sø was bred, I took the pupa 

 in flood refuse on -^^U 1907 and the imago emerged on V5. 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.
