The mouth in Diptera consists of the pharynx, which is divided in 
front into two parts, the epi pharynx and the hypopharynx. This is 
followed by the first metamera, the upper portion of which, combined 
with the epipharynx, forms the labrum ; its lower part is generally sepa- 
rated from the hypopharynx, and forms the labium. Behind this is the 
second metamera, that of the maxillie, and the maxillary lobes are 
simply processes of it, and not jointed organs; the maxillary palpi are 
generally similar, only being jointed to the metamera, and themselves 
articulated in Culex and Tipula. The third and last metamera, that 
of the mandibles, is generally separated from the preceding, though its 
hinder part is strongly soldered to the cephalic plate; it is, however, 
never exposed.
