racular pore band meets body margin 133 



Marginal quinquelocular pores present on at least anterior 



half of body 134 



133. Dorsal 8-shaped pores in a submarginal row : 3-5 quinquelocular 



pores in each spiracular band__ unoietae, new species, p. 58. 



Dorsal 8-shaped pores absent : 10-12 quinquelocular pores in 



each spiracular band radiation, new species, p. 175. 



134. (132) Dorsal 8-shaped pores absent; marginal row of 8-shaped pores 



terminating one and a half to two times the length of 

 an apical seta from setal bases, tbe space between pores 

 about equal to a pore"s width __ eireularr. new species, p. 66. 

 Dorsal 8-shaped pores present : marginal row of 8-shaped pores 

 either terminating slightly more than the length of an 

 apical seta from setal bases and the space between pores 

 equal to at least twice a pore"s length, or the row terminat- 

 ing three to six times the length of an apical seta fr< in 

 setal bases and the space between pores equal to at least 

 a pore's length 13." 



135. Tubular ducts around 12 ti long: marginal row of 8-shaped 



pores terminating slightly mure than the length of an apical 

 seta from setal bases, the pores usually two to four times 



a pore's length apart parvum, new species, p. 148.
