 nel-shaped, with smaller end at opening: anal ring without 

 pores, the ring setae around 1.'- ,u long: disk pores on ven- 

 tral surface of abdomen in complete transverse rows, re- 

 placing multilocular pores gemmae, new species, p. 97.

 ventral surface well removed from margin : anal tube 

 not funnel-shaped, with one end only slightly smaller than 

 the other; anal ring with pores, the ring setae at least

none anterior; marginal row of 8-shaped pores terminating 

 at least twice length of an apical seta from setal bases ; 



insects rather slender 116

 ginal row of 8-shaped pores terminating much less than 

 twice length of an apical seta from setal bases: insects 

 slender or stout 118

where each spiracular pore band meets body margin, inter- 

 rupted between anterior and posterior spiracular pore 

 bands; marginal row of 8-shaped pores terminating two 

 and a half times the length of an apical seta from setal 



bases solenophoroides (Green), p. 192.

 midpoint between antennae and anterior spiracular pore 

 bands and ending 2-12 8-shaped pores from the posterior 

 8-shaped pores, continuous between anterior and pos- 

 terior spiracular pore bands: marginal 8-shaped pores 

 terminating at least three times the length of an apical 

 seta from setal bases 117

gin ; insects elongate and very slender, usually about 1.75 

 mm. long and 0.25 wide: marginal row of 8-shaped pores 

 interrupted near anterior end. and terminating four to 

 eight times the length of an apical seta from setal bases 

 penicillatum, new species, p. 150.

 gin ; insects not so elongate and slender, around 1.25 mm.

 plete and terminating three or four times the Length of 

 an apical seta from setal bases
