II.—Details of the tracheal system of the adult larva. I, a stction through the posterior spiracle, :J-iiu:h objective ; 2, a section through one of the stigmatic slits ( -[V oil immersion); 3, section through the .interior spiracle (.V oil immer- sion) ; 4, a portion of a tracheal trunk, ^ ol>jective ; 5, tracheal terminations^, peritraciieal cells (peritoneal coat); tr, trachea ; v, vestibule ; s, slits ; h, nuclei of peritracheal cells ; e, mesoblast cells ; pr, fibres of the vestibule^,?-, grating of the slits ; ul, imaginal disc of the anterior spiracle (upper prothoracic disc). Leydig* correctly maintained that these capillaries are de- veloped in the interior of the cells of the connective tissue, but Wistinghausenf has quite recently described them as between * Leydig, Fr.,' Zum Feineren Baudes Arthropoden.'
