PTEROMALIDAE OF N.W. EUROPE 239 



mentioned three type-localities (" Surrey, Oxford and Hertford ") but I can find 

 only the above male in his collection. 



Britain, Ireland, Sweden, Switzerland, Austria ; no doubt widely distributed 

 in Europe. Common in Britain. 



Biology. Reared from Pegomyia nigritarsis Zett. (Delucchi, 1955 : 19) ; Jansson 

 (1952 : 7) recorded Pegomyia albimargo Pand. and Pegomyia sp. as hosts in Sweden. 

 Claridge (1958a : 227) recorded it as a solitary internal parasite of larvae of Pegomyia 

 nigritarsis (Zett.) on Rumex sp. Cameron (1935 : 299) recorded it as parasitizing 

 puparia of Hylemyia seneciella Meade in England, but I have not been able to check 

 the specimens. Imagines May-Sept, (perhaps more than one generation). 



Lamprotatus rusticus Delucchi 



Lamprotatus rusticus Delucchi, 1953a : 208, $. 

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



Type material. Type $ (provenance unknown), in Naturhistorisches Museum, 

 Vienna (not seen). 



Distribution and biology unknown. 



Delucchi (1955 : 12) distinguishes the female of rusticus from those of ornatus and 

 splendens by its more strongly transverse gastral petiole, twice as broad as long, 

 whilst the petiole of ornatus and splendens is said to be less than 1 -5 times as broad 

 as long ; and by the sculpture of the propodeum, which is said in ornatus and 

 splendens to have the median carina, if present, never bifurcate, whilst in rusticus 

 it is described as bifurcate. These characters undoubtedly vary considerably. I 

 have females which I consider to be splendens that have the petiole about twice as 

 broad as long, as described for rusticus, yet they do not agree with the description of 

 the latter in other respects. The status of rusticus needs re-investigation. 



Lamprotatus ornatus Delucchi 



Lamprotatus ornatus Delucchi, 1953a : 206, 9. 

 Lamprotatus ornatus Delucchi, 1955 : 12, 18, <j>. 



Type material. Type (? holotype) $, Austria : Piesting bei Wien, Tschek, in 

 Naturhistorisches Museum, Vienna (not seen). 



In his key to the species of Lamprotatus Delucchi (1955 : 12) gives some characters, 

 relating to the sculpture of the propodeum and petiole, for distinguishing the female 

 of ornatus from that of splendens. I find these characters to be very variable in 

 splendens, for example the median carina of the propodeum may be strong and 

 straight, or weak, or irregular and partly resolved into oblique carinulae. The 

 type of ornatus should be examined to see if better characters exist for distinguishing 

 it from splendens. 



Austria. 



Biology. Unknown.
