Girault has pointed out that Anaphes mellicornis Ashmead is not 

 a Mymarid but a Serphoid, without, however, attempting to deter- 

 mine its real relationship. The type in the National Museum has 

 been examined and is in my opinion identical with Amitus aleurodinis 

 Haldeman. 



The species is apparently widely distributed, the following distribu- 

 tion being shown by the material in the national collection: Amherst, 

 Massachusetts, parasitic on Aleurodes fernaldi, A. W. Morrill, col- 

 lector, September, 1906; Whitesbog, Pemberton, New Jersey, para- 

 site of Aleuroplatus plumosa on cranberry, H. B. Scammell, collector, 

 March 5, 1915; Haddam, Connecticut, parasitic on the same host, 

 W. E. Britton, collector, June 27, 1920; southern California, bred 

 from Aleurodes, species, on Rhus, May, 1908, collector not given; 

 Jacksonville, Florida, W. H. Ashmead, collector; Guanajuato, Mex- 

 ico, A. Dugio, collector, June, 1903; four specimans, without locality, 

 reared from "maple leaf Aleurodes February 20, 1874." The types, 

 which are in the Academy of Sciences of Philadelphia, were reared 

 from an Aleurodid on Cornus in Pennsylvania. The types of the 

 Forbes description were from (Aleurodes) Aleurochiton forhesii (Ash- 

 mead) in Illinois. Ashmead records the species from the vicinity of 

 Washington, but I have been unable to locate his specimens.
