Remarks on generic synonymy. Halticoptera Spinola. Whether this is really the 

 genus to which we currently apply the name is problematic. Spinola's brief 

 diagnosis would apply to many genera of Pteromalidae, and the original material of 

 his type-species (if it still exists) has not been examined. However, the name has 

 been applied to the present genus for many years and is therefore retained in this 

 sense. If Spinola's type material should be located and prove to represent something 

 different, then the valid name for the present genus would be Pachylarthrus. 



Tityros Walker. This is now recognized with certainty following my discovery of 

 the type specimen of poreia Walker, the type-species. Ashmead (1904 : 277) placed 

 Tityros with a query as the male of Dicyclus Walker. 



Key to European Species 



(Females) 



1 Malar space about equal to transverse diameter of eye, and about two thirds 



as long as an eye. Vertex slightly elevated in middle, behind the ocelli ; 

 temples about half as long as eyes. Median area of propodeum strongly reti- 

 culate. Gastral petiole as long as or (usually) slightly longer than broad, 

 reticulate ....... smaragdina (Curtis) (p. 159) 



Malar space less than transverse diameter of eye. Vertex not distinctly 

 elevated behind the ocelli ; temples most often distinctly less than half as
