joints 11 and 12 ; a small dorsal linear spot on joint 4, a round one on 
joints 5 and 11, yellow. Green dorsal blanketdike patch reaches to the 
lateral horns extending over joints 6 to 10 and running back laterally 
beneath the subdorsal horns to end in a point on joint 12. It is edged 
with black and white in the following manner: A subdorsal crimson 
brown dash on joints 6 and 10, a dusky band above the lateral horn ; 
central elliptical patch crimson brown, blackish at the edge, then crim¬
