 yellow. Antennae variable, 7 -jointed, about '30 millim. long ; 

 joints 1, 3, and 4 nearly equal in length ; formula : 1 (3 4)

 digitules slender, with expanded ends. Anal ring with six 

 hairs. Mentum is situated in front of the insertion of the 

 first pair of legs ; rostral loop short, extending halfway to the 

 middle pair of legs. The entire surface of the body is 

 covered with straight and curved spines and minute round 

 glands. The abdomen ends in a pair of small tubercles. 



Larva (just hatched). — Orange, pyriform ; the abdomen ends

 Between the tubercles there are two long and four shorter 

 hairs. The surface of the dorsum bears six longitudinal rows 

 of large sharp spines and numerous small tubercles. An- 

 tenna} 6-jointed, joint 3 the longest. Legs small, claw long 

 and slender and slightly curved ; digitules slender. Anal
