Flys Psyche {April 
(as Mik has also done), that there are a number of species of Fucellia 
in which the posterior femora are simple in both sexes, and which yet 
belong to Fucellia beyond a doubt. 
The specimens before me show the following distribution:—Great 
Caribou Isl., Labrador, July 14th (G. M. Allen); Caribou Isl., 
Lab., (Packard); Funk Isl., Newfoundland, July (Owen Bryant); 
Eastport, Me., July 15 (Johnson); Dover, N. H., April 11 (Brid- 
well); Hampton, H. N. (Shaw); Beverly, Mass., April 24 (A. P. 
Morse); Framingham, Mass., June 6 (Frost); Cohasset, Sept. 8 
(Bryant); Fall River, Mass., April 20 (N. S. Easton); Kingston, 
R. I., March 27 (Barlow); New Haven, Conn., Nov. 9 (Viereck); 
Clemonton, N. J., April 15, and Philadelphia, Pa., March 12 (John- 
son); Bermuda, March 6 (F. M. Jones); St. Augustine and De 
Funiak Springs, Fla., March Ist (Johnson); Charlotte Harbor, Fla. 
(Mrs. Slosson). 
From the Pacific Coast Prof. Stein has described five new species: 
~Fucelha bicruciata, Behring Strait; IF. costalis, Monterey, Cal.; F. 
~ antennata, Alaska; F. separata, Monterey, Cal. and Seattle, Wash., 
and I. rufitibia, Pacific Grove, Cal.

It appears to be the regular occurrence among many species of 
Empis, and also in at least some species belonging to Pachymeria 
and Rhamphomyia, for the males to capture small Diptera and other 
insects which they paralyze with their beaks, and then offer to the 
females to feed upon during copulation. ‘The male does not appear 
to partake of this food itself and simply offers it to the female which 
devours it while pairing. Several other species of Empis were found 
to copulate without prey, and females of these were found feeding at 
other times, although those which copulate with prey were not found

to feed at other times.
