TAXONOMY OF MUSCOIDEAN FLIES — TOWNSEND I37 



A small female from Costa Rica (Schild and Burgdorf) differs 

 only in its smaller size and in having the apical cell rather more than 

 short-petiolate. More material is needed to demonstrate its dis- 

 tinctness. 



Galactomyia tropicalis female. — This is a large robust form, with 

 hind femora distinctly ciliate near tip. Body wholly black. Palpi 

 lighter colored, bases of femora reddish. Apical cell closed in mar- 

 gin. Male not known. Closely allied to lanipcs. (Mexico, Costa 

 Rica.) 



Galactomyia radiata H. Loew. — Mr. C. W. Johnson has males 

 from New Jersey, Pennsylvania, and New York. He also has a 

 female specimen collected by him at Delaware Water Gap, New 

 Jersey, July 10, 1898, which is doubtless the female of this species. 

 It has the palpi yellow and bases of femora yellow. The hind 

 femora are short-bristly-ciliate distally. The abdomen is reddish 

 yellow, except anal segment, which is wholly shining black including 

 narrow posterior border of preanal segment. A female specimen in 

 the U. S. N. M., and others that the writer has collected in the Dis- 

 trict of Columbia, agree with this specimen in Mr. Johnson's collec- 

 tion and are no doubt females of radiata. 



The writer wishes to especially thank Mr. Johnson for kindly 

 placing his private collection at his disposal, and for many other 

 favors. 



Subfamily Ameniin^ 



Genus Amenia Robineau-Desvoidy 



Amenta leonina J. C. Fabricius (det. Coquillett). — Australia. 

 Both sexes show broad ventral plates overlapped by sides of dorsal 

 plates. 



Subfamily Amphiboliin.e 



Genus Amphibolia Macquart 



Amphibolia fulvipes Guerin (det. Coquillett). — Australian genus. 

 This species shows in both sexes posterior triangular views of ven- 

 tral plates where the rounded-off posterior corners of dorsal plates 

 fail to cover them from view. The male shows a very large paired 

 plate-like hypopygial process similar to that of Rutilia. 



Subfamily Rutiliin.E 

 Genus Rutilia Robineau-Desvoidy 



Rutilia spp. — The species are all Australian. An examination of 

 specimens of both sexes of several species in U. S. N. M. reveals
