latter should be placed as a family of Cyclorrhapha, close however

 either of these views, but am firmly convinced, from a study of the 

 mouth-parts and head of Lonchoptera and Phora, that the two 

 forms are more closely allied than has generally been supposed. 



In the following list I have endeavored to give a number of the 

 species of Phoridae whose habits have been at least to some extent 

 observed. 



GENERAL. 

 Phora living in caves. Packard, Am. Nat., V, 1871, 745.

 Phorid larvae emerging from a hornet after its death. (Verrall.) 



SPECIFIC. 

 Phora bergenstammi Mik. In putrid snails (Mik). 



Phora microcephala Lw. Lives on dead caterpillars, but is not a true para-

(Rondani).
