the genitalia. He probably knows the family better than any living 

 lepidopterist, but as yet he has not published any revisionary work 



on it. 



From my own studies I feel that the only possible way to get a 

 classification that will permit of workable keys and the ready identi- 

 fication of moths of both sexes is to make small genera, to limit them 

 to only obviously related species, to define them rigidly, and in the 

 definition to utilize every available character of structure, habitus, 

 and biology. I do not suggest that I have done this here or shall 

 be able to do it in future papers on the group ; but such is the ideal.

 with sinus and strong scale tuft ; basal segment simple. Labial pal- 

 pus upturned, oblique or porrect, stout ; third segment always ex- 

 posed, never longer than second. Maxillarj' palpus alike in both
