Abstract: | The salivary glands consist of a pair of elongated tubules, each with a narrow cuticlelined efferent duct. Anteriorly both ducts unite to a cuticle-lined common channel connected to the pharynx: The secretory part of the glands possesses a short neck of peculiar cells that constitute the passage to the efferent duct. The neck epithelium of Haematopota and Hybomitra has subcuticular dense patches that appear to develop into small intracellular mucous goblets, most conspicuous in Haematopota. The contents of the differentiated goblets stain positively according to the PAS procedure and are believed to hold glycoproteins active in the digestion of blood meals. Corresponding cell organelles are not recorded from the genus Chrysops. |
