The digestive system occupies the greater part of the body cavitv andconsists of various well-defined portions, which differ in the several ordersaccording to the nature of the food. It will be understood that in many Insectswhose habits change during their life period, considerable modification takesplace in this svstem. The breathing system of Insects is a most remarkable one, which must bedealt witli in a separate A ; mnarkabk- locust from the- Congo, which was caught in the act of catcliiug aud ratiug a luous,-, aud is now witli its victim preservedm the Natural Museum at South Keusingtou.

The general impression respecting gra^hoppi-rs and locusts is that they arepurely vegetarian Insects. It is from that point of view that they are universalhconsidered ; but it is highly probable that creatures possessed of such efficientcutting jaws vary their diet, at least on occasion. \\V have kepi examples of A Mouse-catching Locust.
