 the rest quadrate or transversely oval ; smaller white spots 

 at base of anal flap, and still smaller ones placed irregularly 

 over the body ; a crimson subspiracular stripe, continuous

 legs pink, each segment with a narrow black band ; prolegs 

 with shank yellowish-green, ankle and foot black ; distal
