Cheshire (1886) states that the stomachs of queens contain a substance which is " microscopically indistinguishable from the so-called royal jelly," scarcely a pollen grain being discoverable in it. If this is so, it would seem to prove that the queen is fed this substance by the worker, for the stomach of the latter is invariably filled with a dark-brown slime containing a vary- ing amount of pol- len and in no way resembling royal jelly. Cheshire further says that before impregna- tion the stomachs of the queens al- ways contain pol- len, the royal jelly being found in them two or three days after impreg- nation, when all traces of pollen have disappeared. The narrow oesophagus (fig. 42, CE) is a simple tube with a thick chiti- nous lining and muscular walls. The epithelium (fig. 45) is very rudi- mentary, its cell boundaries being lost and its nuclei (Nu) appearing as if imbedded in the lower layers of the thick transparent intima (Int). The muscles are disposed in an outer layer of trans- verse fibers (TMcl) and an inner layer of longitudinal ones (LMcl). The honey stomach (fig. 42, IIS) is simply an enlargement of the posterior end of the oesophagus lying within the anterior part of the abdominal cavity. It is best developed in the worker (fig. 44 A), but is present also in the queen (B) and in the drone (D). The organ should perhaps have been named the nectar stomach, for its.
