PTEROMALIDAE OF N.W. EUROPE 799 



was thought to have been destroyed. Actually there are remains of the collection 

 in Oxford and it contains two specimens identified as deplanatus ; one is a female of 

 Psychophagus omnivorus (Walker), the other a female of Diglochis sylvicola (Walker) ! 

 It seems advisable to preserve the current usage of the name deplanatus and disregard 

 the above specimens. From the description of deplanatus by Nees (1834 : no) 

 it appears very probable that he had at least three species mixed under that name. 

 On page in he states " Mares et feminas primo vere et autumno ad fenestras cubiculi 

 Sickershusae observavi. Majo mense in Pruno Pado, Julio aliis in floribus deprehendi". 

 The first sentence suggests the species currently known as Cyclogastrella deplanata, 

 which sometimes swarms in old houses ; the second sentence might refer to the 

 specimens still extant, particularly to the female of Psychophagus omnivorus, which 

 according to its label was captured in July. In order to define objectively the name 

 deplanatus, the best course would be to apply to the International Commission with 

 a proposal that the lectotype of domesticus (Walker), the next junior synonym, 

 should be made neotype of deplanatus, 



Ormocerus simplex Walker. One male, LECTOTYPE, bearing a Waterhouse 

 label. 



Pteromalus domesticus Walker. Lectotype designated by Graham (19566 : 259). 

 Walker synonymized his species with deplanatus Nees in 18456 : 1142, footnote. 



Pteromalus artemon Walker. Syntypes, 5 specimens. LECTOTYPE, the third 

 specimen, an unlabelled male. 



Pteromalus merope Walker. Syntypes, 3 specimens. LECTOTYPE, a male 

 bearing a Waterhouse label, also one reading " 38. 7. 12. 205 ". 



Pteromalus phasis Walker. One male, LECTOTYPE, bearing a Waterhouse 

 label. 



Pteromalus acco Walker. One female, LECTOTYPE ; it bears a Waterhouse 

 label, also one in C. Ferriere's handwriting " Pseudomicromelus deplanatus Nees ". 



Pteromalus androbius Walker. One female, LECTOTYPE, bearing a Waterhouse 

 label. 



Cyclogastrella quercina Bukovskij. Location of type material (from Tortrix 

 viridana L. in the Crimea) not known to me. 



Widely distributed in Europe ; North Africa (Morocco). 



Biology. Parasite of various Tortricoidea, e.g., Tortrix viridana L., Cacoecia 

 sorbiana Hiibn., Semasia diniana Gmel. 



Long ago Walker (1845a : 850) recorded the species (under the name of Pteromalus 

 domesticus) as a parasite of Lozotaenia (=Cacoecia) xylosteana (L.) and (18456 : 

 1 142) of Tortrix viridana (L.). These records went unnoticed for some years and 

 there was some speculation regarding the hosts of deplanata until Scott (1922 : 56) 

 bred several from pupae of Tortrix viridana (L.). C. deplanata often appears in 

 large swarms in buildings. Walker (1835 : 481) recorded it " on the windows and 

 walls of houses in infinite numbers during July, and more sparingly throughout the 

 rest of the year " ; later (1845a : 850) he remarked that it " lives throughout the 

 year, being torpid during the cold weather, though the occurrence of a mild day 

 often draws it from its retreats ". Scott (1919 : 13-16 ; and 1922 : 59-60)
