Two new katydids are described from Costa Rica extending the known range of\ Melanonotus\ northward. The contrast in life history and morphology between primary forest katydids and secondary growth or temperate species is discussed. The absence of regular nightly stridulation and morphological differences such as the extremely long antennae of the two\ Melanonotus\ species and other primary forest epiphyllic katydids are suggested as adaptations to bat predation.

Males and females of the oedipodine grasshopper Sphingonotus rubescens crepitate by producing a click-buzz sound. Males have 3 types of stridulation: (1 and 2) a common whistkle-click combination lasting less than 1 sec and often followed by a hop-turn or very short flight, and (3) a bussing lasting ca. 1.2 sec when 2 or more males are less than 1m apart. Male courtship behviour is described.
