Sometimes the pole is made long enough to hold four sacks, so that four rows are dusted at one time. This is exceedingly simple and practical, and has the advantage of re- quiring no expensive outfit. We have belonging to this series of semi-loopers a number of moths belonging to the genus Plusia, and most of these have somewhere in the middle of the fore-wing a dash, line, circlet, or other marking of silver or gold. Sometimes the entire surface is metallic or golden, and the species, as a whole, are very hand- some, with the ground color in most cases velvety gray or brown. Bright colors or contrasting markings are rare. Several of the larvae attack cultivated plants, but none as frequently as that of P. brassicce, the cabbage Plusia. The caterpillar is green, with rather indistinct lateral lines, and is readily sepa- rated from the butterfly larva of Pieris rapes, because it lacks one pair of abdominal legs and is not at all velvety in appear- ance.
