and sugar-cane, but its injuries are most pronounced on corn and 
cotton. The moth (tig. 36, a) is variable from j^ellow to bufi", and there 
is variation in the degree of marlvings of the fore-wings. The expanse 
is about three-fourths of an inch. The larva (/>, c) is also variable, the 
ground colors running through pale and greenish yellow to dark jq\- 
low. It seems probable that, as two generations have been observed 
in the Middle States and three in the South, the life history of this 
species is not materially different from 
that of the beet webworm. Eggs are 
deposited on lower surfaces of leaves, 
and the caterpillar, soon after hatch- 
ing, draws together the edges of a 
leaf by means of its web, or fastens 
together two contiguous leaves, form- 
ing a shelter, from which it crawls 
forth to feed. A parasite of this 
species is shown in figure 37.

satisfaction against both of these web-

less surrounded by webs and leaf tis- 
sues offering little or no barrier to 
the effects of the poison. In addi-

the burning of all waste material and weeds, are of service in coutrol-

MISCELLANEOUS CATERPILLARS. 
In addition to the caterpillars which have been mentioned — cut- 
worms, army worms, and webworms — a number of other forms of 
different classes and with varying habits are so frequently found in 
beet fields as to deserve consideration. The first two that will be 
mentioned are naked caterpillars; the last two are hairy caterpillars, 
or woolly bears, as the}^ are familiarly termed. 
THE WHITE-LINED MORNING SPHINX. 
{DeUeph'da Vineaia Fab.) 
An illustration and short account of this species, known also as the 
purslane sphinx, is presented, because it is frequently found in beet 
fields and evinces an apparent preference for beet among cultivated 
plants. From its veiy large size it might be judged a pest of impor- 
tance. On the contrary, it feeds naturally on purslane, seeming to
