Marginal 8-skaped pores usually not more than a pore's length 

 apart ; if the row of these pores terminates more than twice 

 the length of an apical seta from setal bases, then there is a 

 distinct row of marginal quinquelocular pores ; if marginal 

 quinquelocular pores are absent, then there are at least 8 

 quinquelocular pores between spiracle and body margin 139 



139. Marginal row of 8-shaped pores terminating about two and a 

 half times the length of an apical seta from setal bases ; 

 atrium of spiracle slightly enlarged and containing 1 or 2 

 quinquelocular pores mimicum, new species, p. 130. 



Marginal row of 8-shaped pores terminating not more than 

 the length of an apical seta from setal bases ; atrium of 

 spiracle not enlarged and not containing pores 140

 pores dorsad of marginal 8-shaped pores

 Dorsal 8-shaped pores absent ; without a row of disk pores 



dorsad of marginal 8-shaped pores 141 



141. Marginal 8-shaped pores rather elongate and slender, 12-14 fi 



long and around 5 wide ; tubular ducts about 34 \x long ; 

 17-32 quinquelocular pores in each spiracular band 



abieetum, new species, p. 35. 

 Marginal 8-shaped pores not so elongate and slender, about 8 n 

 long and 4.5 wide : tubular ducts about 24 n long ; 10-18 

 quinquelocular pores in each spiracular band 142 



142. Marginal row of quinquelocular pores single, starting between 



antennae and anterior spiracular pore bands and ending 

 about half way between posterior spiracular pore bands 

 and the posterior marginal 8-shaped pores 



miliaria miliaris (Boisduval), p. 129. 

 Without marginal quinquelocular pores or with 2-15 (usually 

 less than 6) such pores where each spiracular pore band 

 meets body margin, interrupted between anterior and pos- 

 terior spiracular pore bands
