of anterior tarsi longer than those of the two posterior pairs: middle and posterior pairs, femora four-angled, narrow above broad and flat below with spines on all four edges; of the middle pair the femora and tibiæ are of equal length, 7 lines long, with an elevated spine on the outer edge of the tibiæ at the upper end: posterior pair, femora and tibiæ also of equal length, 8 lines long. Hab. Seventy-mile Bush, near Norsewood, County Waipawa; 1883: W.C. Obs. I may also note that this specimen had lost its anterior left leg, and that a new one was growing to replace it. This new leg is very small and slim, less than 1 inch in total length, but agreeing in all minute particulars with the right one, save that its more salient points were not fully developed. I suspect this loss of limb is a matter of rather common occurrence among the Bacilli,—from the great length of their slender legs, their habitat among the green leaves of trees in the exposed windy branchlets, and their known fighting and cannibal propensities. I have already noticed an instance of similar mutilation, in my description of B. sylvaticus (Trans. N.Z. Inst., vol. xiv., p. 278). Section Saltatoria. Family Locustidæ.
