A female Dorcasina matthewsi
A female Dorcasina matthewsi (Leconte, 1869). This is one of those species where the description leaves something to be desired. The species was described from pinned specimens so the color of the elytra is said to be testaceous, note that the living specimen is actually yellow. The females tend to have black antennae and legs, while the males are reddish brown (as mentioned in the key). The spots are variable, the typical having just the middle spot (more reduced) and infuscated elytral tips. This is just an extremely dark specimen. It fooled me at first, but I got out my old copy of Swaine & Hopping (1928) and then Linsley & Chemsak, and read all the fine print. The diagram of the elytral pattern in Swaine and Hopping is nearly identical to this specimen.

I'm thinking back to Judolia now

could this be J. quadrata (LeConte)??

We based our suggestion
of Dorcasina on one image in one text - definitely not a strong ID!!
We would certainly trust Guy's recommendation over our own amateur suggestion, but have to say yours doesn't look like VJ's to us, but we have been known to flub big time on cerambycids! Let us all know if you get any more info.

 
My best guess
I have not had alot of specimen face time with these particular lepturines, so mine is also only a suggestion, but if you take and reduce the markings, the pronotal and elytral shape is a good match, along with leg coloration and the general size Some of these guys can be quite variable in maculation, especially between localized populations, and some of the more subtle ID characteristics don't show well in photographs, if at all. Kinda makes me crazy!! in a good way.......I guess thats the fun in it!
