Found under a lighted wall just before dawn, about 6:00 a.m. This very large (body length 42 mm, head-to-wingtips, 64 mm) Tibicen is very pruinose. I suspect it is Tibicen auletes, and comments confirm this. Interesting that this individual was found within a few meters of the only other individual of this species I've been able to photograph, but almost exactly two years previously--image now deleted, since it was of poor quality.
