same veinlet in them. Finally, on examining two male specimens 
in ray cabinet, the magnifier shows this vpinlet in them also. 
Several months have now passed since the above examinations 
were made, and to M. Amyot’s question, why have not I seen this 
veinlet if it really exists,? I have supposed I could only reply, 
Look, and you certainly can see it. But yesterday, taking up the 
first specimen that came to hand, the magnifier showed this vein- 
let in the wings fully as distinct as the longitudinal veins, and 
apparently of the same thickness with them. I thereupon im¬ 
mersed this specimen in alcohol, and looking at it now as it lies 
in the alcohol in a white saucer, I am wholly unable to see this 
veinlet, although the longitudinal veins are perfectly plain. On 
a most careful inspection, I should say decidedly, there is no such 
veinlet there. I now drain off the alcohol and dry the specimen, 
and still as it lies undisturbed on the white surface of the saucer, 
the space between the longitudinal veins appears perfectly 
hyaline with not the slightest indications of a veinlet crossing it, 
that I am able to discern ; and now I really begin to fear my yes¬ 
terday’s inspection was not made with sufficient care. Finally, 
on carefully separating the wing from the surface of the saucer 
and holding it up between my eye and the light, lo, there is this 
same veinlet again, exactly as I remember it looked before, as 
thick as the longitudinal veins and of the same dark color and 
opacity, although but a half ininute ago the space it occupies 
appeared perfectly hyaline and colorless. 
Now I cease to wonder why M. Amyot did not see this veinlet. 
Looking at the same specimens which he did, as they were lying 
in alcohol, I know I would have said as decidedly as he did, that 
there was no cross veinlet in their wings, and therefore they could 
not be the species which I had figured. But I am very sure M. 
Amyot cannot examine a half dozen specimens of this insect, pre¬ 
served as we usually have tl*em in our collections, without becom¬ 
ing perfectly assured that this veinlet does exist in their wings. 
Before leaving this subject it will probably be expected that I 
say a few words upon two other points alluded to by M. Amyot 
as having strepgthened him in the opinion that our American 
insect was different from the European. These points ai;e the 
width and roundness of the ends of the wings, and the thickness 
of the body in my figure of the female, as compared with the 
figure of it given by Mr. Curtis. As I refer so frequently to Mr.
