APHELINUS MARLATTI (Ashmead). 



Bacochatis marlatti Ashmead, Kans. Agri. Exp. Sta. Bull. 3, 1888; Ap- 

 pendix, p. V. 

 Aphelinus subapterus Girault, Ent. News, vol. 27, 1916, p. 405. 



Both of the above-cited descriptions are based upon the same three 

 identical specimens. The Aslimead description was apparently un- 

 known to Girault. In addition to the three specimens mentioned as 

 types by both authors the National Collection now contains two other 

 specimens acquired by gift from the Kansas State Agricultural Col- 

 lege in 1920, and which were reared by Mr. Marlatt at the same time 

 and from the same source as were the types. Two of the type speci- 

 mens have been mounted on a slide and ground to fragments beneath 

 the cover-glass by Girault. The actual type specimen is mounted 

 on a card point in good condition except for loss of both antennae, 

 and the pin bears a label on one side of which is written the Ash- 

 mead name and on the reverse side the Girault name. 



COCCOPHAGUS LECANII (Fitdi). 



Platygaster lecanii Fitch, 5tli Kept. Ins. New York, 1858, p. 25. 

 Coccophagus lecanii Smith, Amer. Nat., 1878, p. 661 ; Seventh Rept. State 



Ent. 111., 1878, p. 130. 

 Coccophagus ater Howard, Rept. Ent. U. S. Dept. Agri., 1880, p. 359. 

 Coccophagus cognatus Howard, Rept. Ent. U. S. Dept. Agri., 1880, p. 359. 

 Coccophagus flavoscutellum Ashmead, Florida Agri., vol. 4, 1881, p. 65. 

 Coccophagus vividus Howard, Bull. 5, Bur. Ent. U. S. Dept. Agri., 1885, 



p. 25. 



With the exception of flavoscutellum Ashmead and cognatus How- 

 ard the above synonymy is that given by Doctor Howard in his 

 Revision of the Aphelininae of North America. 



The writer recently had occasion to compare the types of Coc- 

 cophagus lecanii (Fitch), G. cognatus Howard, and C. flavoscutellum. 

 Ashmead, all of which are in the National Collection. After care- 

 ful comparison and study the conclusion was reached that all three 

 names refer to the same species. Fitch's species is slightly variable 

 as to the extent of the yellow marking on the scutellum and both 

 Howard's and Ashmead's types fall well within the range of this 

 variation and can not be distinguished from lecanii otherwise. 



The species attacks a long list of Lecaniine and other scale insects 

 and is widely distributed, having been recorded from Europe by 

 Masi ^ and others ; from Japan by Nakayama ; * from Hawaii by 

 P""ullaway ^ and in America it is known to occur from the Atlantic 

 to the Pacific and from Florida to Ontario, Canada, as well as in 

 several of the West Indian Islands.
