Description of the Female of Aphzenogaster fulva Roger. 
—I have found the winged females of Aphenogaster fulva in the nest 
on the 15th of July and flying on July 17. This sex, hitherto unde- 
scribed, is closely like the worker, but is larger (length six to seven 
millimeters), and the metathoracic spines are blunt. The wings are 
hyaline, the stigma and nervures yellow: there is sometimes present a 
second recurrent vein (received by the second submarginal cell), and 
in one specimen before me there is a stub of a vein projecting into the 
first submarginal cell from the second submarginal cell.

Spread of the Horn Fly.—This insect (Hematobia serrata), 
which apparently was introduced into the United States from Southern 
France in 1887, having been first noticed in New Jersey that year, 
has rapidly spread west, north and south. In a recent issue of the 
“Southern Live Stock Journal” Mr. H. E. Weed says it is now com- 
mon in most of the Southern States east of the Mississippi River. It 
-is abundant in Ohio, and has lately been migrating northward in New 
England. I recently visited a locality (Hartland) in Vermont, a few 
miles south of Hanover, N. H., where the insect is abundant and is 
causing considerable annoyance to dairymen. Spraying affected cattle 
with kerosene emulsion is proving the most practicable remedy.—

Chinch Bugs in New Hampshire.—The chinch bug (Blissus 
leucopterus) has been reported a number of times from New England. 
In Massachusetts specimens have been collected at Cambridge by Drs. 
Harris and Dimmock, and at Salem by Dr. Packard. In Maine they 
have been collected by Prof. H. L. Fernald and Dr. Packard. The 
latter has also taken specimens at the summit of Mt. Washington in 
New Hampshire. The present season I have taken three specimens 
of this species at Hanover, N. H. Two of the short-winged form were 
taken April 23, under boards along a pasture fence, and one of the 
normal long-winged form was swept from grass early in June. These 
were the only specimens that oceurred during the season’s persistent 
collecting —C. M. W.
