ABT. 4. NEW PARASITIC HYMENOPTERA GAHAN. 11 



That this difference is not of specific vakie is apparent from an 

 examination of the 20 specimens constituting the original type series 

 of semifla'vus. In this series the size of wings vary from normal 

 to scarcel}'^ half normal size. The same tendency to vary is shown 

 by a series of specimens reared from Myzus persicae Sulzer at Colum- 

 bus, Ohio, by E. A. Hartley and the same tendency is shown by the 

 three specimens constituting the type series of hrevipennis. Both 

 sexes show the same tendency to vary in the size of the wings but 

 the reduction is apparently carried to a greater extreme in the male. 

 In addition to a large number of specimens reared from Myzus 

 persicae the National Collection possesses a male and female of this 

 species reared from Myzus, species on Aquilegia, at Lafayette, 

 Indiana, May 7, 1916, by J. J. Davis. 



APHELINUS LONGICLAVAE Mercet. 



Aplielinus longiclavae Mercet, Assoc. Espan. Prog. Ciencias (sep.), 1911, 



p. 14. 

 Aphelimts capitis Rust, Ent. News, vol. 26, 1915, p. 73. 



This species was originally described as a parasite of Aspidiotus 

 hederae Vallot in Spain. Apheliniis cajntis was described from 

 California where it was said to parasitize a number of different 

 species of scale insects including Aspidiotus hederae. While no 

 European specimens of longiclavae have been seen by the writer two 

 cotypes of capitis together with three other California specimens 

 reared by E. O. Essig from Asjyidiotus hederae have been compared 

 with Mercet's description and seem to agree so perfectly that I have 

 no hesitation in declaring Rust's species to be a synonym. 



APHELINUS CHRYSOMPHALI Mercet. 



Aphelinus chrysomphali Mekcet, Bol. Real. Soc. espan. Hist. Nat., 1912, p. 

 135 ; Trab del Mus. de Cien. Nat. de Madrid, 1912, No. 10, p. 67. 



Five slide-mounted specimens reared from Aspidiotus destructor 

 Signoret on coconut palm at Rio Pedras, Porto Rico, October 17, 

 1921, by G. N. Wolcott, have been determined by the writer as this 

 species. The record is interesting as constituting the first identifica- 

 tion of this European species from the Western Hemisphere. 



APHELINUS ASHMEADI, new name. 



Aphelinus hotvardii Ashjlead, Trans. Ent. Soc. London, 1900, p. 264 (not 

 hotcardii Dalla Torre, Cat. Hymen., vol. 5, 1898, p. 221). 



This species was described from a single male specimen from the 

 island of Grenada, West Indies. The type is in the British Museum. 

 If really an Aphelimis the species should be easily recognized by the 

 unusually long male antennae.
