In 1889 Meinert 1 ) described as Philornis molesta n. gen. 
n. sp. the 3’ stage of a maggot occurring in subcutaneous sacs on 
a nestling bird from Brazilia. This maggot is very similar to 
Mydæa anomala but differs in some respects, viz. the anterior 
pharyngeal sclerite being broader and without the strong spine on 
the upper margin; still it is possible that the pharyngeal skeleton 
of the Philornis when drawn has been lying in a position that the 
spine has coincided with the anterior part of the sclerite, and thus 
given the impression of the whole sclerite being broader. The 
number of knobs in the anterior spiracles are recorded as 5 in 
Philornis, while I have never seen more than 4 in the 3’ stage 
larva of Mydæa anomala. The general appearence and the po- 
sterior spiracles seem to be quite the same in both larvæ. — At 
all events Philornis molesta and Mydæa anomala are closely re- 
lated species. 
The synonomy of this species is thus the following:

Here I may point out, that when the Katalog der palæark- 
tischen Dipteren III gives Philornis molesta Mein. as synonymous 
with Protocalliphora azurea Falk, this is only due to the authors 
lack of knowledge of the Danish language. They have not realized
