placed in synonymy with Norbanus Walker by Peck (in Muesebeck et al., 1951). I 

 have examined the syntypes of the type-species of Norbanus (dysaules Walker) in 

 BM(NH) ; the species was described from material taken at St. John's Bluff, 

 Florida. I have not seen the type-species of Stylophorella Ashmead but I accept 

 the synonymy proposed by Peck (195 1). 



The European species of Norbanus need revision. I feel uncertain as to how 

 many are valid ; Szelenyi (1941) recognized three belonging to the group of 

 scabriculus (Nees), but the differences between them are very small, whilst some 

 of those he mentioned do not seem to work out consistently. At present I am 

 prevented by lack of material from attempting a revision of the species. In my 

 key I have noted some differences between scabriculus (Nees) and meridionalis 

 (Masi) which may be valid. The other species, globulariae (Szelenyi), giordanii 

 (Ferriere) and albicans (Masi) I have not seen. 



Key to Two European Species 

 (Females) 



1 Antennal flagellum fuscous to black with at most the apex of the clava pale. Head, 

 and thorax dorsally, relatively duller, with rather denser sculpture. Head 1-2 to 

 1-25 times as broad as the mesoscutum. Legs with femora and tibiae fuscous, only 

 the knees and the tips of the tibiae narrowly pale. Stigmal vein of fore wing dis- 

 tinctly curved ........ scabriculus (Nees) (p. 438) 



- Antennal flagellum brown, or testaceous with the incisures between its segments 

 blackish. Head, and thorax dorsally, more shiny, with rather less dense sculpture. 

 Head 1-3 to 1-33 times as broad as the mesoscutum. Legs relatively paler, 

 especially the tibiae which are more broadly pale apically, sometimes fully the distal 

 third of the hind tibiae is pale. Stigmal vein hardly curved 



meridionalis (Masi) (p. 439) 



I am unable to provide a key to males.

Norbanus scabriculus (Nees) Peck, 1963 : 740-741. 



Type material. Types presumed lost (none amongst the remnants of Nees' 

 collection in Oxford). It will probably be necessary to erect a neotype when the 

 species of the genus are revised. This could be selected from the material in the 

 collection of Thomson, who first revised scabriculus ; but preferably perhaps from 

 that in the collection of Ruschka, which seems to agree better with the original 

 description. Ruschka's specimens were also re-examined by Masi (1922c) who 

 noted some differences between them and his new species meridionalis. 



Nees (1834) stated that the wings of female scabriculus were " obscure hyalinae "
