Euchlaena irraria (Least-marked Euchlaena - Hodges#6739) ???

In a discussion on this image
we started to wonder about these two
and if any (or all three) may really be Eusarca confusaria (Confused Eusarca - Hodges#6941)
http://bugguide.net/node/view/4507/bgimage
Any expert opinions?

Euchlaena vs Eusarca
The top image (211938) is an Eusarca confusaria, and the other two images are correctly ID'd as Euchlaena irraria. Note the PM lines of the FW. In E. confusaria the PM line is slightly straighter, and comes to a point nearly reaching the apex, whereas in E. irraria the PM line curves away from the apex toward the costa (no point) and doesn't come nearly as close to the apex either. Hope that helps.

 
Thanks
It makes sense now. I was placing too much value on the scalloping vs. smoothness of the wings.

 
No problem
You'll also notice some variation in E. confusaria where some specimens will have a more falcate FW apex.
