 although they are not so opaque as the wings of Moths usually 

 are, they are yet not sufficiently transparent to allow anything 

 to be seen through them. 



The colour is a rather dull but pure and very soft white, 

 with a kind of downy look about it. The wings are edged with

The reader will probably have noticed how widely the pheno-

 resemblance, not only in form but in colour, and generally 

 in manners. Take for example a recent instance, Eunomia 

 hcemorrhoidalis, and see how closely it resembles the Clear-wing 

 Hawk Moths, and how closely they in their turn imitate bees
