The wing-venation of 18 males of toinncyl was studied in 

 detail and the more significant variations illustrated, together 

 with the fore tibia with its strap-like appendage. The illus- 

 trations of this and other species (Plates VII, VIII) are 

 almost self-explanatory, though it might be noted that no effort 

 was made to indicate the very inconspicuous pupal setae. 



The generic references of these four insects are admittedly 

 unsatisfactory ; but not only the literature of exotic species, 

 but more complete knowledge and representative series of the 

 insects themselves are requisite for a better understanding of 

 this puzzling and interesting group. "One is compelled to 

 conclude" (Tutt, British Lepidoptera, II, 127, 1900) "that 

 the higher Psychids are almost unknown, so far as their 

 relationships to each other are concerned."
