 a white stripe across and over the mouth parts and on each 

 side of the inverted Y. The ground color of the upper part 

 of the bod}^ is evidently light blue, with a dorsal row of oval 

 orange spots, one on each segment ; two sub-dorsal orange 

 lines ; also, two lateral orange lines. Between the sub-dorsal 

 lines is a number of crinkled black and orange lines ; between 

 the sub-dorsal and lateral lines the space is blue, slightly- 

 variegated with fine orange and black lines intermingled. The 

 lower part of the body and feet are dusky blue, with crinkled, 

 orange and black irregular lines, and an amber-colored ring 

 around base of pro-legs. The caterpillars do not make a tent 

 or web, although they live in colonies on the tree.
