There is a mistake in the Letter of Aristeas 2 in Penner, Ken, and Michael S. Heiser. “Old Testament Greek Pseudepigrapha with Morphology.” Bellingham, WA: Lexham Press, 2008. Both the lemma and the parsing are wrong:

It should be the verb πειράζω and the parsing should be, ptc, pf, mid, dat, ms.
But, there is only the ability to report typos under the "selection" not under the either "lemma" or "morph" in the context menu. I can, of course, report the typo under "selection" but it will be less specific.
