August, 
Head fairly small, quite smooth. Antennae short to very short, com- 
posed of from 29-36 (according to Meinert up to 40) very short segments. 
Ocelli 9-12, large in proportion, in straight rows generally appearing to 
be arranged in the following manner : i +5, 4, 2 ; — i +4,5,2 ; — i 4-4, 4, 3 ; 
—1+4, 3, 2 ;— 1-I-3, 3. 2 ;— i-f4, 3. I. 
Coxae of the maxillipedes armed near the deep median cleft with 2-I-2 
small and pointed teeth. Dorsal plates from almost smooth to slightly 
wrinkled or granulated and uneven, the 9th, nth and 13th bounded behind 
almost rectangularly ; the nth and 13th however sometimes produced 
into httle angular projections, which really only arise because the pos- 
terior border is somewhat excavated on both sides. Sculpture of the 
ventral plates indistinct.

inner. Claw distinct and deeply tripartite.
