towards the dorsal margin ; apical margin broadly greyish (a trace of 



a similar marginatiou is also seen in the anterior wings) ; some of the 



longitudinal veins obscure ; most of the transverse nervules whitish 



hyaline ; finely pubescent as in the anterior wings. Legs yellow, the 



tibiae and tarsi with black dots and spines ; tarsi tipped with black ; 



first and last tarsal joints longer than the others ; tibial spurs as long 



as the first tarsal joint; claws very long, directed downwards, nearly 



straight, with incurved tips, shining brown. 



I possess two examples from Japan. It is placed provisionallj 



in Glenurus ; but it possesses many characters in common with 



Creagris, from Avhich it differs in the great length of the antennae, 



and gradually dilated wings.
