1908] The Genus Pros [)altclla 283 



Type No. 12 164, U. S. N. M. Described from three female 

 specimens reared by Dr. A. W. Morrill, Orlando, Fla., from Aley- 

 rodes coronatus. 



There is also in the collection of the Bureau of Entomology 

 of the Department of Agriculture one specimen of what seems with 

 little doubt to be this species, reared by Albert Koebele from males 

 of a Kermes on Quercus undulata at Nogales, Ariz., May 3, 1897. 

 On the same slide are several specimens of an Amitus (Procto- 

 trypidae) , and also several shriveled males of an Aphelinine which 

 may possibly belong to the species above described, but their 

 condition will not warrant a description.
