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.
