 short and slender, with buttoned ends. Tarsal digitules 

 slender, scarcely reaching to the tip of the claw. Uostral

 transverse rows. The ventral surface of body bears glands 

 and many small hairs.

Antennas usually 8-jointed, although sometimes joints 3 

 and 4 are united into one; slender, joints 4-7 slightly ex- 

 panded at the distal end. Allot the joints bear hairs. Joint 

 8 the longest. Approximate formula: 8 3 (2 1) 5 4 (6 7). 

 Antennaa varying in length from "60 millim. to '70 millim. 

 Average length of antennal joints: (1) 89, (2) 89, (3) 102, 

 (4) 64, (5) 84, (6) G2, (7) 62, (8) 133.
