Genus PALLURA, Walker

This genus has ahvavs bcen referred tn the 1'hoiidae, but after a careful e.Kamination of \Valker's 

 desciiption, I feel assured that it does not belong here. In spite of \Valker's notorious inaccuiacy, it is 

 hard to see how he could havc made a mistake when the family characters are so unique. but I am 

 nevertheless inclin(>il to bclievc that Pallnia is a memVier of the Borborida'. 



Geographical distribution of species. — There is only a single species, from the Ai u Islands.
