The maxilla is egg- shaped with the broad end toward the mouth, and is clothed by irregular narrow plates which form concentric circles about the maxillary palpus. This palpus, of the same size as the labial palpus, is situated near the mouth opening. It is composed of a short peg-like projection set in a heavily chitinized Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of America.
