. The Australian zoologist. Zoology; Zoology; Zoology. Fig. 4.—Edwardsina australiensis. A, pupa; B, pupal respiratory organ, seen from the side. The average size of the oval-shaped pupa is 7 mm. long and 4 mm. broad; it is at once distinguished by the peculiar breathing organs, without analogy within the family, but otherwise it differs in no important feature or in coloura- tion. The brownish red integuments are densely covered with granulations and on the third to seventh abdominal segments there are two groups of markings, (1) some punctiform depressions in the same arrangement as those of the larva and, (2), on each side a rather deep, oblong, obliquely placed foveole. These markings are to be observed already in the pupa in formation within the larval body (fig. 1A). The respiratory organs are composed of three elements, (1) basally and posteriorly an elongated subrectangular ehitinous plate, (2) before the latter, but extending more towards the sides, another elongate plate, roundish in sec- tion, (3) disposed on this, an,d transversely and perpendicularly to it, a series of about 18 closely approximated lamellae, which gradually increase in size from the exterior to two-thirds of the series, and then decrease slightly. These lamel- lae are thus placed in planes approximately parallel to the sagittal plane of the pupal body, and the respiratory process with such an organ is rather difficult to understand. If a cross section is made between two lamellae (fig. 5A) it is seen that the wall of the tracheal extension makes a loop between the suture of.
