The larvaj of certain species that prey upon the Hop Plant-louse in the East are well known to the hop- pickers as " black niggers " or " ser- pents," and are carefully preserved Coior^Biackand ^i' ^^^^^ "^ some of their most effi- oranse. clcut fricuds. The eggs of Ladybirds greatly resemble those of the Colorado Potato-bug, and are scarcely distinguishable except b)' their smaller size ami by a much smaller number being usually col- lected together in a single group. As these eggs are often laid in the same situation as those of the potato-feeding insect, care must be taken by persons who undertake to destroy the latter, not^to confound those of their best friends with of their bitterest enemies. In the larva state the Colorado Potato-bug is extensively depredated on, both in Illinois, Missouri and Iowa, by the Spined Soldier-bug. n ownaudspeck- ttnd yellow. (Arma spinosa, Dallas, Fig. 41 b). Thi-usting forwards his long and stout beak, he sticks it into liis victim, and in a short time pumps out all the juices of its body and throws away the empty skin. He belongs to a rather extensive group (Scutellera family) of the true bugs {Ileteroptera), distingviishable from all others by the very large scutel, wliich in tliis genus is triangular, and covers nearly half liis back. Most of the genera belonging to tliis group are plant-feeders, but there is a sub-group {Sp
