lacked head and antennae, Ratzeburg's mistake in placing it in Pteromalidae is not 

 surprising. 



Pteromalus Orthia Walker, 1839 : 22 3> S- Type material : 1 <^, LECTOTYPE,

Nomina nuda 



1. Megorismus Aon Walker, 1848 : 109. (See note under Leptomeraporus nicaee.) 



2. Pteromalus Cytoeum Walker, 1848 : 125. This is represented in Walker's 



collection by a $ Habrocytus, but was never described. 



3. Pteromalus festucae (Walker) Moncreaff, 1871 ; see Moncreaff, 1871 and 



Walker, 1871 : 2436. Walker merely stated " Mr. Moncreaff . . . reared 

 Decatoma mellea, Pteromalus fulviventris and P. festucae (n.sp.) from galls 

 on Festuca ". He also appended a note in Moncreaff 's paper, stating that 

 one specimen of P. festucae had been reared from stems of Festuca ovina. 

 The name is cited without comment in all the catalogues but I doubt if it 

 is valid, since there is no description and the data given in the papers cited 

 can hardly be construed as indicating the " work " of the species. I have 

 found no specimen labelled festucae in Walker's collection. One of three 

 cards marked "Moncreaff" standing under Pteromalus imbutus Walker 

 bears a $ of Habrocytus microps sp.n. which might have been the original 

 specimen of festucae, but there is no proof of this.
