SOME FURTHER REMARKS ON THE SYSTEMATIC 

 AFFINITIES OF THE PHORIDiE, WITH DE- 

 SCRIPTIONS OF TWO NEW NORTH 

 AMERICAN SPECIES.* 



By Charles T. Brues. 



In a recent paper published in the Transactions of the Ento- 

 mological Society of London 1 , Mr. W. Wesche has dealt with 

 this interesting question, and as his paper is in part a criticism 

 of my last contribution along this line 2 , I think it desirable to add 

 a few brief remarks. 



W r esche has unfortunately completely misunderstood the posi- 

 tion which I have taken in regard to the Phoridse and Hippo- 

 boscidse. In the paper above referred to (do. 354 and 357) I

have called attention to many striking resemblances between these 

 two families, but it is expressly stated that "these resemblances 

 are undoubtedly the result of parallel development." It was not 

 my intention to imply that they indicate genetic relationship, for 

 I most emphatically' believe that they do not. The undoubted 

 recent geological development of the Hippoboscidse and their evi- 

 dent adaptation to a peculiar habitat must preclude any idea that 

 they are closely connected with the evolution of such compara- 

 tively generalized Diptera as Phoridse. As can be seen from my
