Here are some things to look for on these two species:
Check out the ST line on the wings. (with, vs. without the thick-dark shading) This is the most obvious difference. In M. absorptalis, it is almost an exact copy of the PM line and reaches all the way to the apex.
In M. hypocritalis it is much thinner and lighter than the shading on the PM line and usually it fades out well before the apex. Next, check out the terminal line. (solid, vs. dashed)
