A study in the comparative anatomy and morphology of insects; with plates and illustrations executed directly from the drawings of the author; CUbiodiversity4765349-9885 Year: 1890 ( 86 THE LARVA OF THE BLOW-FLY. under water. It consists of a median dorsal and two lateral lobes. Sections show that the omentum is much folded and convoluted, that it occupies the greater part of the body-cavity, and has large blood sinuses between its folds. The cells of the fat body (Fig. ig,/ 6) measure about o'i5 mm. in diameter; they consist of a reticular protoplasm, in the meshes of which granules and globules of fat are imbedded. These are so numerous that they conceal the nucleus. Sections show that the cells are bounded by a thin cuticular membrane. These cells have large vesicular nuclei, which undergo very remarkable changes during the development of the nymph.

(For details see ' Histology of Tissues.') The fat body, although adherent in places to the larger tracheal vessels, has no tracheal capillaries developed on its surface. When removed from the larva and exposed to the air, it rapidly assumes an inky hue, probably the result of The contents of the cells are not easily acted upon by osmic acid, unless the outer wall of the cell is ruptured.
