In cross section it has the shape of an Q, the com- pletion of the tube being formed by the apposi- tion below of the hypopharynx. The labrum is blended with the epipharynx, but does not extend to the tip. The hypopharynx is a thin, flat two-edged lamella closely applied to the under surface of the epipharynx. It is pierced by the salivary duct down which the salivary secretion and sporozoits pass. The opening of the duct is continued as a groov

Showing relation of Pharyngeal and Salivary Pumps to the Proboscis The mandibles are very fine chitinous rods in cross section, crescentic in shape. At the tip of the mandibles are about thirty serrations, though in certain species of Culex these appear to be absent. The mandibles are closely applied to the sides of the epipharynx. The maxillae are stouter than the mandibles, and fit around the outer side of these and the.
