Time change of O2 and CO« concentration in a sealed chamber containing a single pupa. was sealed in a rigid water-filled glass chamber connected to a tuberculin syringe. A trace of detergent was added to the water to eliminate surface bubbles. A small closed-end manometer in the chamber indicated pressure. The volume increments necessary to change the pressure were used to compute the volume according to Boyle's law. The pleated cuticle structure was assumed to exert no mechanical resistance to compression. The tracheal volume was about 5% of that of the entire body (average of 10 readings). For a 5-gram pupa this amounts to 250 This method gives less spread (4% to 7%} than that of Buck and Keister (1958). Levy and Schneiderman (1958) have provided the only figures on tracheal gas composition. After a ventilating burst, pO2 and pCO2 are, respectively, about 18% and 3%. During the initial interburst period pO2 drops rapidly to 5% and pCCX increases slightly to 4%. Over the several hours until the next burst, pCX remains constant and pCO2 rises to about 6%..
