Seladerma bicolor Walker 



Seladerma bicolor Walker, 1834 : 289, $. 

 ? Seladerma luteolum Delucchi, 1955 : 53, 9. 



Type material. Seladerma bicolor Walker. One female in BM(NH), LECTO- 

 TYPE, bearing a Waterhouse label, also one in C. Ferriere's handwriting " Type 

 CF ". There is a female in the Greville collection but probably this is not a syntype. 



Seladerma luteolum Delucchi. Type $ (not seen) in coll. Forster, Naturhistorisches 

 Museum, Vienna. Delucchi's description of luteolum suggests that it might be the 

 same as bicolor Walker. 



Britain : England, near London (Walker) ; Scotland (probably near Edinburgh), 

 one female in coll. Greville ; ? Germany (coll. Forster). Apparently rare. 

 Biology. Unknown. 



Seladerma coeruleovirens (Forster) 



Lamprotatus coeruleovirens Forster, 1861 : 34, " <J " [recte $]. 

 Seladerma coeruleovirens (Forster) Delucchi, 1955 : 49, 54, $. 



Type material. Type (? holotype) $ in coll. Forster, Naturhistorisches Museum, 

 Vienna ; Delucchi (1955 : 54) pointed out that Forster had mistaken its sex. I have 

 not seen the specimen. 



Switzerland : Oberengadin, Rosegtal. 

 Biology. Unknown. 



Seladerma convexum Walker 



Seladerma convexum Walker, 1834 : 290, $. 



Type material : one female, designated LECTOTYPE (possibly holotype), bearing 

 a Waterhouse label and a green-bordered type label. 



Britain, local : near London (Walker) ; Berkshire, Wytham, 9^.1962, females 

 and male swept on calcareous grassland (Graham). 



Biology. Unknown. 



It is possible that 5. agreste Delucchi (1953a : 216, $) might be the same as con- 

 vexum Walker ; I have not seen the type $ of agreste and Delucchi does not mention 

 some distinctive characters which are present in convexum, hence I am uncertain. 



Species belonging to Seladerma but whose specific identity is uncertain : — 



Lamprotatus Phlegias Walker, 1844a : 332, <$ (Lapland). LECTOTYPE (possibly 

 holotype) $, Type Hym. 5. 798, bearing a Waterhouse label. This must belong to 

 the group of diffine (Walker), i.e., to Telepsogos s. str., but it does not quite fit the 

 known males of any of the species listed above. It may therefore represent a valid 

 species.
