side piece some distance from the tip. The outer margin of the tip 

 has the usual fringe of spinules, and the inner edge has a series or 

 rather a brush of small spines. 



Auranticolor is a bright yellowish red-brown form, with violet pow- 

 derings especially distinct along the inner margin and through s. t. space. 

 It is very distinct from all the preceding, and forms the bridge to the 

 other groups. No S has been examined. 



Lignicolor differs from all the preceding by the indistinct claviform, 

 and lack of distinct connecting shade between the median lines. The 

 color is more dull than in auranticolor but also very similar. The gen- 

 italia are as in antennafa, the clasper somewhat dilated towards the tip. 



Oenialis is closely allied, but the maculation is obsolete. The geni- 

 talia are almost identically like those of lignicolor, and a comparison 

 of the figures will show best wherein they differ. 



Relicina is related to cinefacta, but is bluish gray, and has the me- 

 dian lines very strongly dentate, and so is easily recognizable. 



Centralis is also related to cinefacta, but is a more whitish gray, with 

 more even median lines, and an obviously darker, somewhat contrast- 

 ing median space.
