ABT. 8 jSTOTHS on parasitic HYMEITOPTEEA GAHAX 7 



Arnold Foerster, and other authors located there. Through the 

 abundant courtesy of the custodian, Dr. F. Maidl, cotypes of a 

 number of European species were secured for the United States 

 National Museum collection. Among these were two cotypes of 

 Encyrtus a'pliidivorm Mayr. These have been compared with the 

 common encyrtid parasite of aphids in America and found to agree 

 in every respect. 



This parasite, as shown by the above list of synonyms, has been 

 several times described in America and its identity has been some- 

 what obscured by reason of the fact that it has been confused by 

 both A. A. Girault and the writer with {Encyrtus) Zarhop<il/m in- 

 quisitor Howard. Encyrtus inquisitor was described by Howard 

 from a single female from Jacksonville, Fla. A female specimen 

 in the National collection labeled " Jacksonville Florida " also bears 

 the label " Type No. 2616 " and the name label. This specimen was 

 accepted by both Girault and the writer as the actual type specimen 

 without particular reference to the description, and on the basis of 

 a study of the alleged type the writer, in 1927, synonymized Afhi- 

 dencyrtus a'phidi'pliagus (Ashmead), schizoneurae (Ashmead), web- 

 steri (Howard), and megowrae (Ashmead) with inquisitor 

 Howard. Howard's description and figure of inquisitoi"^ however, 

 can not possibly apply to the alleged type as has been correctly 

 pointed out by P. H. Timberlake.^ Timberlake is without much 

 doubt correct in placing inquisitor Howard in the genus Zarho'paius 

 where Ashmead had previously placed it. 



The two references by Griswold (1926 and 192T) under the name 

 Aphidencyrtus inquisitor are based upon determinations made by 

 the writer after comparison with the false type and refer to apM- 

 divorv^ Mayr instead of inquisitor Howard. 



COPIDOSOMA NANELLAE Silvestri

Several specimens of a parasite received from K. A. Salman of the 

 Massachusetts Agricultural College and said to have been reared 

 from larvae of Recurvarla thujaella Kearfott collected in Maine 

 during the summei' of 1927 seem to agree in every respect with the 

 description of Copidosoma 'nanellae Silvestri, a species which Sil- 

 vestri records as parasitic upon RecurvaHa nanella Hilbner in Eu- 

 rope. R. nanella is known to occur in America, and the parasite 

 appears to have been accidentally introduced with its host and to 

 have taken to the related American species R. thujaella. According-
