been found useful in destroying these beetles." Similar 
remedies migbt possibly apply to the twelve-spotted 
galereuca. 
As these insects are not sufBciently numerous to do 
any harm to the cotton crop, these remedies are merely 
mentioned as applying to the cucumber-beetle, or any 
other pests of the garden or fields, of similar habits. 
Span-Worms, or Loopers. — {GeometrcB?) 
Among the numerous insects which injure the flowers 
of the cotton plant may be found several caterpillars, many 
of which are of the kind termed "loopers," or "span- 
worms," from their peculiar mode of locomotion. 
Near Columbus, in Georgia, I found a species of cater- 
pillar which were quite numerous, about an inch and a half 
in length, and of a bright-green color, eating the petals of 
the cotton flower, from the 12th of October to the 29th of 
November. They had six pectoral, four ventral, and two 
anal feet, and were obliged to loop their bodies when pro- 
gressing from place to place, after the manner of the so- 
called span-worms or loopers. Their bodies were green, 
and slightly hairy. The chiysalides were seven-tenths of 
an inch in length, and of a green color. The moth, with 
wings extended, measures about an inch and three-tenths, 
is of a shaded or clouded blackish brown, with a metallic, 
gold-colored semicircle near the centre of each upper-wing ; 
a round spot of the same color also lies close to it, but 
nearer the margin ; the under- wings and body are of the 
same blackish brown. When at rest, the upper-wings 
come together like the roof of a house ; a tuft of hair 
projects from the upper part of the thorax, and a smaller 
tuft is found near or between the junction of the wings, 
which appear to curve up toward the outer margin.
