Cockroach
generally, any insect of the family Blattidx, or at least, of the family Blattidæ, or at least, of the genus Blatta; and specially, the B. orientales, so common in houses, particularly in seaport towns. The cockroach is said to have come originally from India, through the Levant. It is nocturnal in its habits. The eggs are deposited in horny cases, in which they are arranged with much regularity, in two rows, with a central partition, and smaller ones isolating each egg from the other.
