THE IMMATURE STAGES AND BIOLOGY OF THE CRANEFLIES TOXORHINA-CALEDONICA AND ELEPHANTOMYIA-GARRIGOUANA (DIPTERA, LIMONIIDAE)

The larval and pupal stages of the craneflies Toxorhina (Ceratocheilus ) caledonica Alexander and Elephantomyia (Elephantomyia) garrigouana A lexander are described. The habitat and certain biological behaviors o f Toxorhina and Elephantomyia are noted. Similarities and differences in structure of the immature stages of the two genera are listed and t heir importance in the determination of relationships discussed The ch aracters support a close relationship of the two genera, and confirms the placement of the two genera within the Eriopterini. A possible err or in the rearing of one species of Elephantomyia from South Africa is also discussed.
