 bristles, other joint with fewer bristles. Second antenna 4-jointed; 

 1st as long as other three combined; 2nd joint about one-third 

 as long as 1st, expanded at tip and bent backward so that the distal 

 limb of the antenna is nearly parallel to the proximal limb ; 3rd 

 joint short with three or four strongly curved stiff bristles upon its 

 distal lower angle; 4th joint with seven long curved unequal ter- 

 minal bristles; the upper edges of the last two joints are fringed with 

 short spines. Mandible strong with a hooked toothed and jointed 

 terminal claw; palp(?) one-jointed with three strong, and as many 

 slender, bristles. First maxilla(?) one-jointed with three irregular

 much swollen with two lancet-like plumose bristles on its inner edge; 

 distal joint small, with one large heavy claw and two heavy bristles. 

 Maxilliped two-jointed; proximal joint bearing a small lobe (inner 

 ramus ?) with two large bristles; distal joint long, broadly elliptical, 

 with a single two-branched terminal claw, anterior branch bristle- 

 like, posterior branch larger, broad, with four or more bristles on its 

 posterior edge. First to 4th feet with both rami three-jointed. 

 First foot with bristles and spines divergent; 4th foot scarcely 

 differing from the third. Fifth foot two-jointed; distal joint ellipti- 

 cal, twice as long as broad, with two spines on the distal portion of 

 the outer edge, one terminal spine and a short terminal bristle. Two
