Szelenyi (1942 : 103-104) gave a description of a species which he considered to be 

 grande, from material reared in Hungary from Eriopeltis festucae. He stated that 

 specimens of Leucopis silesiaca Egg. (Dipt., Chaemaemyiidae) had emerged together 

 with the Pachyneuron, which he thought had very probably parasitized larvae of 

 the Leucopis. He had not seen the type of P. grande and some features in his 

 description suggest that he had misidentified the species. 



Pachyneuron cremifaniae Delucchi 



Pachyneuron cremifaniae Delucchi, 1953 : 8, $. 

 Pachyneuron cremifaniae Delucchi, 19556 : 127, 131, $. 



Type material (not seen). Syntypes reared at Laimbach, near Munich, Germany, 

 Spock (Bavaria), and Seegraeben (Switzerland, Canton of Zurich) in May and 

 August 1950 ; type $ in coll. C.I. B.C. 



Females of cremifaniae appear to vary somewhat in the relative length of the 

 gaster and the degree of flattening of the thorax.

Biology. Delucchi (1953, 1954) and Delucchi and Pschorn (1954) originally 

 reared the species as a parasite of Cremifania nigrocellulata Cz. (Dipt., Chamaemyi- 

 idae) ; Delucchi (19556) also recorded two females reared from a species of Leucopis 

 (Dipt., Chamaemyiidae) .
