We have siuli profound and often expressed admiration for our 

 eminent English friend that we trust no offense can be provoked b)' 

 our earnest desire not to see him spasmodically descend to the level 

 of his, often undeservedly, abused countryman, Francis Walker, and 

 without his excuse. 

 BoRKHAUSENiA HAVDENELLA, Chambers. PI, XXXVIII, Fig. 5. 



Blepharocera Iiaydenella, Chambers.

This species which has remained unrecognized since its descrip- 

 tion in 1877 from a unique specimen from Colorado in spite of consid- 

 erable effort to place it, is now definitely determined and we are able 

 to dispose of the long standing empty generic name Chambersia Riley. 

 The credit for this interesting identification is entirely due to our 

 friend Dr. J. H. McDunnough. who collected and determined three 

 male specimens at Silverton, Colorado. We have carefully gone over 

 the generic and specific characters and find it to be a very distinct spe- 

 cies of the genus Borkhausenia. 



It is generically identical in all respects with the Australian genus 

 Crossophora Meyrick, which was separated from Borkhausenia only 

 by the somewhat longer ciliation of the male antennae, a character 

 also found in our N. Am. B. ascriptrlla Rusck and as already stated 

 (Proc. U. S. Nat. Mus., Vol. XXX\', p. 204. 1908) a character which 

 can not be maintained as of generic value.
