PTEROMALIDAE OF N.W. EUROPE 843 



Israel. I have been informed that in the latter case it was a hyperparasite. One 

 suspects that it may normally act as a hyperparasite. Ferriere and Voukassovich 

 (1928 : 28) found that in the vicinity of Belgrade it was hyperparasitic on eight 

 species of Braconidae Aphidiinae which were attacking various aphids on different 

 plants ; they also suggested that aphidis might sometimes be a hyper-hyperparasite. 

 There are other host-records for aphidis in the literature, but those mentioned above 

 are the best authenticated. In western Europe imagines are most frequent in the 

 field in July and August. 



EUNEURA Walker 



Euneura Walker, 1844a : 331. Type-species : E. augarus Walker, by monotypy. 

 Eunevra Agassiz, 1846 : 427 [invalid emendation]. 



Hypsicamara Forster, 1856 : 52, 54. Type-species : H. ratzeburgi Reinhard, 1859, by sub- 

 sequent reference. 

 Hypsicamera Dalla Torre, 1898 : 168 [invalid emendation].

 Euneura Walker ; Peck, 1963 : 621-622. 

 Euneura Walker ; Peck et al., 1964 : 39. 



Hypsicamara Forster was synonymized with Euneura by Peck (in Muesebeck 

 et al., 1951 : 541). 



As will be seen from my keys to the genera of Pteromalinae above, the differences 

 between Euneura and P achy neuron are slight. Perhaps Euneura may eventually be 

 regarded as a subgenus of Pachyneuron though for the present I consider it best to 

 keep them separate. 



Key to European Species 

 (Females) 



1 Clypeus, face, and frons (Text-fig. 685) with coarser and conspicuously strigose 

 sculpture, the longitudinal striae being strong, the transverse walls of the areoles 

 weak. Fore wing with distal half or more of basal cell pilose ; speculum nearly 

 always closed below, occasionally partly open ; marginal vein hardly thicker at 

 apex than at base ........ augarus Walker (p. 844) 



- Clypeus, face, and frons (Text-fig. 686) with finer sculpture, the longitudinal striae 

 relatively less strong, the transverse walls of the areoles more distinct, than in 

 augarus. Fore wing with basal cell bare, or with at most 4 isolated hairs distally ; 

 speculum open below ; marginal vein about 15 times as thick at apex as at base 



laeviuscula sp. n. (p. 844) 



The <£ of augarus has the same characters as those noted above for its $ ; that of 

 laeviuscula sp. n. is not yet described.
