The blatta americana, which is very common in Brazil, where it inhabits human dwellings, is an orthopterous insect, with an elongated, oval, rather flat body, from 12 to 16 lines in length, of a brown-red which becomes paler under the belly. The prothorax is smooth, shining, of an ochre yellow, with two large brown spots, which are sometimes united in one. In the male the elythrae reach beyond the belly by a few lines; in the female they are a little shorter. They are marked with numerous longitudinal streaks which bifurcate near the dotted margin terminating the elytrae. The wings are striate and reticular, of the length of the elytrae. The antennae which are longer than the body, exhibit at their base a small yellowish point. The feet are provided with black prickles and terminate in a tarsus with five articulations. We triturate the whole insect, if possible alive, for 15 minutes; after which we take two or three grains of this paste and rub them down with 100 grains of sugar of milk in order to obtain the first trituration.
