Studies in Australian Katydids: A Review of the Australian Snub-nosed Sylvan katydids (Tettigoniidae; Pseudophyllinae; Simoderini).

The Australian members of the simoderine katydids are reviewed. The tribe is known from nine genera, five of which occur only in Madagascar, the others are Australian: Chloracantha Hebard (C. lampra, C. angularis sp. nov., C. garradunga sp. nov., C. hilleri sp. nov.), Tallebudgeroptera gen. nov. (T. spininota sp. nov.), Mastigaphoides Weidner (M. haffneri, M. tuberculatus sp. nov., M. vaginalis...

Generation of extreme ultrasonics in rainforest katydids.

The calling song of an undescribed Meconematinae katydid (Tettigoniidae) from South America consists of trains of short, separated pure-tone sound pulses at 129 kHz (the highest calling note produced by an Arthropod). Paradoxically, these extremely high-frequency sound waves are produced by a low-velocity movement of the stridulatory forewings. Sound production during a wing stroke is pulsed, b...

Pink Disease *

physical signs of disease in lung still present, though less marked than on admission. General health improved, but not restored. In the 1930-1 report, Sir St. Clair Thompson states :-"Out of thirteen cases with laryngeal tuberculosis, approximately thirty per cent. were "arrested," while sixty-six per cent. of the remainder were "improved." These figures suggest that with more modern methods o...

Since then numerous descriptions have appeared, including that of Feer, a German paediatrician. Several names are still current, e.g., erythrcedema, acrodynia, dermato-polyneuritis, while in ...
