JS. hudsonias, with report that they were injurious to pole beans, as 
will be mentioned more in detail in consideration of the latter species, 
at Milo Center, Yates County, N. Y. 
Mr. Edward C. Post, Dundee, Mich., who sent specimens of this 
beetle in 1889 from Monroe, Mich., wrote June 21,1900, transmitting 
specimens taken from four different fields of sugar beet some 5 miles 
apart and about 18 miles from Monroe. In two of these fields the 
beetles did considerable damage. 
August 8, 1900, Mr. Carroll Fowler, of the Agricultural Experi- 
ment station, University of California, at Berkele3 T , Cal., sent speci- 
mens of this beetle with the information that they had been received 
from Mr. W. W internal ter, Rocky ford, Colo., where they were do- 
ing considerable damage to sugar beet. Mr. Winterhalter describes 
the work of this beetle as follows: 
It bores the leaves from the upper side, boring regular holes clear through the 
leaves, and, as it appears in swarms of millions, it practically kills the plants which 
are two or three weeks above the ground. These flies have destroyed quite a few 
acres in our Pueblo district. They are doing likewise with cockleburs, sand burs, 
and other weeds. The beets are badly injured and their growth is checked con- 
siderably, but this fly is too small to destroy old plants completely. The specimens 
were collected June 19, 1900. 
During the summer of 1899 imagos were reared July 22 and 23. 
In 1900 imagos of the new generation were observed August 25, over 
a month later. 
May 18, 1901, Mr. W. J. Langston, Sixmile, Ala., sent specimens 
of beetles and cotton leaves, the latter showing severe injury by this 
insect. The beetles had been seen at work only two days. 
May 21, Mr. B. M. Moose, also sent specimens with leaves of 
cotton showing similar injury. He stated that the beetles were very 
numerous on his farm at Simpsonville, S. C, having made their 
appearance two days earlier. Beets were also injured. 
June 20, Mr. A. L. Beals, Deming, Ind., sent numerous specimens 
of this beetle with report that, although the species had been in his 
garden only about three days, it had done great damage, especially to 
radish, beet, bean, melon, and cucumber. 
The Red-headed Flea-beetle (Systena frontalis Fab.). — One of the 
injurious occurrences of the year 1899 was that of the so-called red- 
headed flea-beetle, Systena frontalis Fab., at Syracuse, N. Y., reported 
by Smiths & Powell Compan}^, August 3, as injurious to sugar beet. 
Although this is the only case of damage reported from there during 
that year, it is possible that there was an outbreak of the species in 
that portion of the United States and perhaps Canada, as this insect is 
known to be periodically troublesome in that latitude. 
Systena frontalis was first reported by Mr. William Saunders as 
injurious in the year 1882 (Can. Ent., Vol. XIV, p. 117; 13th Kept.
