PTEROMALIDAE OF N.W. EUROPE 453 



Type material. Syntypes, 2 $ ; LECTOTYPE, labelled " Mrl " [?] and 

 " gibbiscuta Ths ". 



Britain, Sweden, Germany ; North Africa. 



Biology. Unknown. Imagines appear in August. 



The colour of the coxae varies in this species. In the lectotype $ the fore and 

 mid coxae are dark ; but I have a British $, otherwise indistinguishable from the 

 lectotype of gibbiscuta, in which all the coxae are yellow with the exception of the 

 proximal part of the hind coxae.

Gahan (1933 : 96-97) gave a very detailed redescription of febriculosus. The 

 European specimens which I have identified as febriculosus agree perfectly with 

 his description ; they are also conspecific with North American specimens identified 

 as febriculosus (by Gahan and by Peck) which I have been able to examine. Gahan 

 (1933 : 99) also mentioned " In the British Museum the writer has seen two female 

 specimens collected on the Isle of Wight which seemed to agree in every way with 

 American representatives of febriculosus. These two specimens constituted a part 



of the material identified as Homoporus fulviventris (Walker) " I have myself 



examined these specimens [there are actually three, not two] and find that they 

 agree with my own material already presumed to be febriculosus. I am therefore 

 confident that I have identified the species correctly.

I am somewhat puzzled about the identity of filicornis. Some of my specimens 

 of febriculosus, those with entirely pale femora, run in Delucchi's key (1957a : 404) 

 to filicornis Erdos. These specimens, however, do not agree completely with 

 Erdos' original description. For example, they have the postmarginal vein shorter 

 than the marginal, whereas Erdos (1953 : 242) stated that these two veins were 

 equal in length ; and they have the antennal flagellum less slender proximally 

 than is shown in the figure given by Erdos (1953, fig. 10c). On the other hand, my 

 specimens of febriculosus agree well with Erdos' later figures (1961, figs. 1 (<J) and 

 2 ($)) ; in these the postmarginal vein is shown as slightly shorter than the 

 marginal, whilst the antennal flagellum of the $ is not quite so slender as that shown 

 in Erdos' figure of 1953. If the earlier figure, and description of the length of the
