There are tubercles on the body of Porcellio pictus, which is a
striking looking animal. Its head is black with the lateral lobes
curved outwards ; there is a dark band down the
middle of the back and commonly two others
on each side, with more or less conspicuous
yellow markings between.
The distal (terminal) joint of the flagellum
is but half the length of the proximal one and
the last peduncular joint is longer than the
two combined.
The abdominal appendages—1 and 2—are
provided with air-tubes.
