PTEROMALIDAE OF N.W. EUROPE 431 



Dinarmus dacicida Masi. Syntypes, Italy, several localities in Puglia, Calabria, 

 Umbria, and Tuscany. 



D. lesbiacus Masi. Holotype <J, Italy, Isle of Metelino, x.1906. Delucchi 

 (1956a : 254-255) suggests that it is probably the same as dacicida. 



D. virescens Masi. Syntypes, <$ and $$, Syria, Beirut, 1907. Delucchi 

 (1956a : 254-255) believes it may be the same as dacicida. 



Mediterranean Region. 



Biology. Parasite of Dacus oleae Gmel. (Dipt., Trypetidae) ; dacicida, lesbiacus, 

 and virescens were all originally reared from this host. 



Cyrtoptyx robustus (Masi) 



Dinarmus robustus Masi, 1907 : 288, $ $. 

 Dinarmus robustus Masi, 1921a : 271, 275. 

 ? Dinarmus cynipidis Masi, 1921a : 271, 275-276, $. 

 Cyrtoptyx robustus (Masi) Delucchi, 1956a : 254. 



Type material (not seen) in Istituto di Entomologia agraria, Portici. 



Dinarmus robustus Masi. Syntypes, Italy, Umbria, Bevagna, several specimens 

 reared from galls of Cynips coriaria Htg. 



D. cynipidis Masi. Syntypes, Italy, S. Vito de' Normanni, one female from 

 gall of Cynips tomentosa Trotter ; Corigliano Calabro, one female from gall of 

 Cynips argentea Hartig. These specimens have not been examined either by 

 Dr. Delucchi or the writer; Delucchi (1956a : 254-255) suggested that they were 

 probably the same as robustus Masi. 



Mediterranean Region. 



Biology. Parasitic on Cynipidae, see above under type material ; also records 

 of rearing from Cynips [Andricus] kollari (Htg.) and C. polycera Giraud mentioned 

 by Delucchi (1956a : 255) which refer to material apparently identical with 

 robustus. 



Cyrtoptyx lichtensteini (Masi) 



Dinarmus lichtensteini Masi, 1921a : 271, 275. 

 Cyrtoptyx lichtensteini (Masi) Delucchi, 1956a : 254-255. 

 Cyrtoptyx lichtensteini (Masi) ; Delucchi, 1962 : 123. 



Type material (not seen). Syntypes, Southern France, reared from Mononychus 

 punctumalbum Herbst (/. Lichtenstein) ; one at least of these specimens is in 

 Museum Nationale d'Histoire Naturelle, Paris (see Delucchi, 1956a : 255). 



France, North Africa. 



Biology. Parasite of Mononychus punctumalbum Herbst in France (see above) ;
