Oncodes varius, Kertesz, Cat. Dipt., vol. 4, p. 20, 1909. — Verrall, Brit. Flies, vol. 

 5, p. 462, 1909.— Brunetti, Ann. Mag. Nat. Hist., vol. 18, p. 602, 1926.— 

 Seguy, Fauna France, vol. 13, p. 168, 1926.— Pleske, Konowia, vol. 9, p. 165, 

 1930.— Sack, Die Fliegen, vol. 98, p. 22, 1936. 



Type locality: Europe. 



Discussion: Species of group v. This Eui'opean species may 

 extend east to Siberia as variety siberiensis Brunetti (1926, p. 603), 

 and south to British East Africa and the Belgian Congo as variety 

 pallidimarginalis Brunetti (1926, p. 602). However, it is also quite 

 possible that both of these varieties are distinct species which are not 

 closely related to varius. 



The extremely restricted Nearctic species rufoabdominalis Cole is 

 rather closely related to varius and suggests a Holarctic connection. 

 However, they are easily separated by color characters and the male 

 genitalia (see discussion under rufoabdominalis), In male genitalia, 

 as well as color pattern, varius also shows definite similarities with 

 the Australian basalis (compare pi. 13, figs. 101, 109). 



The European species cingulatus Erichson appears to be conspecific 

 with varius, but Sack (1936, p. 23) did not make the synonymy even 

 though he examined the type of the former species.

Ogcodes gibbosus, Sabrosky, Amor. Mid. Nat., vol. 39, p. 408, 1948. 



Type locality: Europe. 



Discussion : Species of group v. This widely distributed Palaearctic 

 species apparently has no close Nearctic relative with the possible 

 exception of hennigi, new species. Pleske (1930, p. 166) recorded it 

 from the ^Siberian Orient, and while it appears to be rather common in 

 northern and central Europe it has not been recorded from the Medi- 

 terranean region to my knowledge. 



The aedeagus of gibbosus (pi. 8, fig. 43) is quite similar to that of 

 the Nearctic sab roskyi, new species, and of 6o/mr^t, new species; however, 

 except in this feature gibbosus does not appear to be closely related.
