PTEROMALIDAE OF N.W. EUROPE 329 



this group. He described a new genus Platecrizotes (ibid. : 90-91) which he 

 regarded as a Pirenine ; but Boucek (1963 : 503) considered it to be rather closely 

 related to Pachycrepoideus Ashmead [q.v.] and not a Pirenine. I agree with 

 Boucek's view, Bairamlia Waterston, also included in Pireninae by Ferriere (1934 : 

 85, 89-90) was later transferred to Asaphini by Boucek (vide supra, under Bairamlia). 

 Some of the remaining genera which Ferriere included in Pireninae (especially those 

 described by Girault) are not very well known, and some may not be correctly 

 placed there. The genera placed in Pirenini by Peck (1963 : 637-640) show a 

 diversity of hosts which may indicate that the tribe is heterogeneous. He includes 

 not only Macroglenes and Pirene (known hosts : Cecidomyiidae) but also Mesopeltitia 

 (hosts : Coccidae), Herbertia (Agromyzidae), Morodora (Calliphoridae), Bairamlia 

 (Aphaniptera) and Dipachystigma (Col., Scolytidae). Clearly the constitution of the 

 Pirenini needs to be re-investigated, especially with regard to the New World 

 genera. Pirenini, even if only the European genera are considered, approach very 

 closely to Ormocerini ; I cannot therefore give to either of these groups a status 

 higher than that of a tribe. 



Key to European Genera 



1 Males with at least the mid and hind tibiae strongly swollen, broader than 



their respective femora. Females with fore tibiae armed with several short 

 stout spines arranged in a row along their outer edge ; all the tibiae stout 

 but less so than in males. Antennal scape very short, reaching hardly half 

 way from the torulus to the median ocellus. Stigmal vein of fore wing 

 nearly half as long as the marginal vein . . SPATHOPUS Ashmead (p. 332) 



- Males with tibiae not strongly swollen, not broader than their respective 



femora. Females with fore tibiae without spines, or (Ecrizotes) with at 

 most four rather stout spines at the apex of the tibia and a row of fine slender 

 spines along the dorsal edge. Antennal scape relatively longer. Stigmal 

 vein of forewing often relatively shorter ...... 2 



2 (1) Females with antennae with four or five large funicular segments which are 



provided with sensilla. Males [that of monticola unknown] with antennae 

 without visible anelli, with six large funicular segments which are provided 

 with sensilla ; flagellum subfiliform ; hind tibiae (Text-fig. 270) compressed 

 and more or less expanded, without a pecten. Fore wing (Text-fig. 269) : 

 stigmal vein long, from somewhat more than one third, to half, as long as the 

 marginal vein, the stigma with a long petiole ; postmarginal vein fully half 

 as long as the marginal vein, and slightly longer than the stigmal vein 



ECRIZOTES Forster (p. 330) 



- Females with antennae (Text-figs. 276-278) with at most three large funicular 



segments which are provided with sensilla. Males with antennal flagellum 

 (Text-figs. 275, 279, 280) clavate, with some anelliform segments, and at 

 most three large funicular segments ; hind tibiae neither compressed nor 

 expanded, and nearly always with a more or less developed pecten (Text- 

 figs. 281-283). Fore wing (Text-figs. 271, 272) with stigmal vein shorter, 

 from one eighth to one third as long as the marginal vein ; postmarginal 

 vein from one sixth to slightly more than one third as long as the marginal 

 vein, about as long as or shorter than the stigmal vein and often indistinctly 

 defined ............ 3 



3 (2) Fore wing without a speculum ; basal cell pilose except for a narrow strip above 



the cubital vein. Antennae with flagellar segments three to five large and
