subsequent exauiinatiou of the prey, however, it was seen that of the 

 thirty victims, twenty-six from females f (?) in cop. and four from 

 lone males, twenty-two were more or less completely enveloped in 

 a fine veil or shroud-like web of silky tiireads. If, as is su|)po8ed, 

 this web be carried only by the males, it would seem that some of 

 the females must have been feeding on insects caught by members of 

 the opposite sex, and in the absence of fuller information we may 

 take it that this indicates at least the possibility of a parallelism, in 

 essentials if not in detail, betweeu the coupling habits of Hilara 

 maura and of Empis borcnlis. 



The thirty victims of //. maura mentioned above consisted of 

 seven iSimuliids {Simulium latipes) and twenty-three small Chironomids.

[Note. — This is one of two males taken by Lieut. Filchner in his expedition to 

 China; the Dermatoptera wore determined by me, and the account will appear in 

 the work dealing with the Filchner expedition, which is shortly to be published by 



E. S. Mittler und Sohn, of Berlin. The specimens were originally determined us 



F. vicaria, Sem., and are there I'ecorded under that name, but I have recently sub- 

 mitted one to M. A-P. Semenov Tian-Shansky, who has compared it with his 



t Definitely seen in fifteen cases only.
