86. Marginal row of 8-shaped pores terminating about the length 

 of an apical seta from setal bases ; marginal row of quin- 

 quelocular pores terminating 6-17 8-shnped pores from the 

 posterior 8-shaped pores ; without submarginal disk pores 

 interspersed with submarginal 8-shaped pores : apical setae

 Marginal row of 8-shaped pores terminating about the length 

 of a posterior pore from bases of apical setae ; marginal 

 row of quinquelocular pores terminating at the posterior 

 8-shaped pores ; with submarginal disk pores interspersed

Disk pores not in a ventral submarginal row close to submar- 

 ginal 8-shaped pores, sometimes in a row close to marginal 

 quinquelocular pores 90

 quinquelocular pores at opening of spiracle and 10-13 simi- 

 lar pores between group and body margin ; largest dorsal 

 8-shaped pores measuring 16 tx long and 10 wide ; without 

 claws javae, new species, p. 116.

 with 1 pair of rather slender claws in position occupied 

 by posterior pair when 3 pairs are present
