A, cross section, semidiagrammatic, of the abdomen in the region of the ovaries, showing a recently cast cuticula, or molt skin (d), a newly formed cliticula (Q), thehypodcrmis(nyp), the stomach (St), the ovaries (Ov), the heart (Ht;, the ventral nerve cord (VNC), the dorsal diaphragm (DDph), tracheaa (Tra), oeno- cytes (Oe), and fat cells (FC). Between the cuticula Cj and the cuticula Ci is a considerable intercu- tfcular space (). R represents the body wall in this pathological condition, showing the cuticula Ca and the cuticula Tj, both bearing spines (SCj and .S('i), and the intorcuticular space (IS) in which is found evidence of a coagulum formed from the fluid filling the space by the action of tlie fixing fluids. The remaindfT of the body wall, the (Hyp), and the liasoment membrane (BM) are also shown. C, fat i^ell with irregular outline, irregular nucleus (Nu), and deep staining bodies (DSB). IJ, oenocyto with uniformly staining cytojilasm, and with a nucleus (Nu) having a uniform outline. E, a porlJon of the stomach wall showing the epitlinllum (SKpth; during metamorphosis, it being at thfai time <ni\Ui columnar in type, and the musculature (M). (Original.).
