Bjorkvik) in coll. Zetterstedt, labelled in his handwriting " P. mandi=bularis <$ 

 Bjorkvik " ; also labelled by Ch. Ferriere " Lamprotatus annularis Walk." 



Lamprotatus petiolaris Thomson. Syntypes, 4 specimens. LECTOTYPE, a 

 male labelled " Hma " [Holmeja], " Scan ", and " petiolaris Ths.". 



Britain, Ireland, Sweden. Fairly common in Britain. 



Biology. Reared in England from a Dipterous host on Stellaria media (L.) 

 (Delucchi, 1955 : 18). Imagines May-Sept. (? possibly two generations). 



Lamprotatus crassipes Thomson 



Lamprotatus crassipes Thomson, 1876a : 224, $ ?• 

 Lamprotatus crassipes Thomson ; Delucchi, 1955 : 12, 20, <$ $. 



Type material. Syntypes on 8 pins. LECTOTYPE female labelled " L-d " 

 [Lund] and " crassipes Ths." ; the specimen has been remounted by A. Jansson. 



In a small series of specimens, all of which appear to belong to crassipes, there is 

 the following variation : 



Fore femora pale, or with a dark subbasal streak, rarely the basal third darkened ; mid 

 femora usually pale, rarely with a small dark streak beneath ; hind femora typically with a 

 dark mark basally on their external aspect, occasionally with the dark colour somewhat more 

 extensive. Gastral petiole varying from copper through golden-green to bronze. Pro- 

 podeum with panels of median area reticulate, or obliquely strigose-reticulate ; median carina 

 strong to rather weak, either complete and straight, or slightly irregular, or interrupted, or 

 forked in its anterior half ; plicae present in about the posterior half of the propodeum. Raised 

 sculptured part of gastral petiole varying from quadrate to about 1-5 times as broad as long. 



Britain, Sweden, Czechoslovakia ; apparently uncommon. 

 Biology. Unknown. 



Lamprotatus flavus Delucchi 



Lamprotatus flavus Delucchi, 1953a : 203, §. 

 Lamprotatus flavus Delucchi, 1955 : 12, 20, $. 



Type material. Type (? holotype) $, Austria, Innsbruck, 20. v. 1923 (E. Clement), 

 in Naturhistorisches Museum, Vienna (not seen). 



The characters given by Delucchi (1955 : 12) for separating this species from 

 crassipes do not work satisfactorily (compare them with my notes on the apparent 

 variation of crassipes above). It will be necessary to reassess the status of flavus.
