from Austria received from Brauer and Bergeustamm, and by

The above synonymy except the last one is according to Brauer and 
Bergeustamm, 2 who compared the types of these three descriptions; 
these authors state that the type of the genus Arehytas has the pro- 
boscis broken, which accounts for the peculiar form accorded to this 
organ by Jaenuicke. Parafabricia was considered by its founders as 
ir rhis name was proposed by Dr. Williston to replace filipalpis Thorns., preoccu- 
pied. Ou page 301 he gives anaxias Walk, and analis Macq. as probable synonyms 
of kcemorrhoa v. d. W. In the Biol. Cent.-Amer., Diptera, Vol. II, p. 32, van der 
Wulp gives the latter as synonymous with robusta Wied., places analis Macq. and 
filipalpis Bond, in the same category, and states that filipalpis Thorn, may also be 
added to this list. He doubts the correctness of Williston's reference of anaxias 
Walk., owing to Walker's statement that there are "no bristles on the sides of the 
face;" but Walker refers to the facial ridges, and not to the sides of the face as at 
present understood. In the Dipteri del Messico, p. 10, Giglio-Tos places cora Bigot 
as a synonym of filipalpis Rond.
