Male. — Head and thorax deep steel blue black, orbits pure white ; palpi above black, 

 bright orange beneath. Antennae deep steel blue black, with the tip, for one third the length, yel-

Closely allied to S. rubrofascia , but readily distinguishable by the orange red 

 color between the veins on the outer parts of the fore wings and by the palpi 

 being orange beneath. The larva lives in the canes of willow. (Plate XXXV,
