[*The specimen from which this drawing was made is not typical 

 dcceptor, but differs in having 1 the inferior appendages almost as long 

 as the superiors, more strongly curved dorsad in the apical half so 

 that the upper margin of the inferiors is almost a (concave) semi- 

 circle. The dilated part of the superiors is not as much as half the 

 length of the appendages and is a little higher, proportionally and rela- 

 tively, than in other specimens. There are four, not five, antenodal 

 cells and less black on the body generally than called for by McLach- 

 lan's description. These color and venational differences may be but 

 individual variations, judging from other Hawaiian species, but whether 

 the differences above mentioned for the appendages are explicable in 

 the same way, I am unable to decide, having too few specimens.
