The German Cockroach ; a first stage ; b, c, d, second, third and fourth stages; e adnlt; f female with egg-case ; q egg-case enlarged ; h adult with wings spread. All natural size, except g. (After Riley). multiplication of piping in houses enabled it to make its way from one building to another without difficulty, and the dampness and heat of hot water pipes afforded it the most favorable conditions for living and increasing. As its name indicates, it is a European species, being particularly abundant in Germany and the adjacent countries. It has, however, been carried by commerce and emigrants to all parts of the world, and ie now spreading so rapidly in England, owing probably to the immense importation of goods " made in Germany," that Miss Ormerod tells us it is supplanting the familiar English species, known as ''the black ; It is much smaller than the other domestic species, rarely exceeding five-eighths of an inch in length, very light brown in color and distinctively marked on the thorax with two dark brown stripes. It is more active and wary than the larger species and much more difficult to get rid of; it also multiplies much more rapidly, the breeding period being shorter and a greater number of eggs being produced at a time. The Oriental cockroach is the common species in England, where it is known in the household by the name of " the black ; It is supposed to be of Asiatic origin, and to have spread through Europe several centuries ago. It is very dark brown,- almost black, in colour, shining, and much stouter than the other species. The wings of the male are shorter than the body and in the female are so abbreviated as to render her practically wingless. It is notably gregarious in habit, the individuals living together in colonies in the moat friendly manner. This species was brought in early days to the British settlements
