Also from Marquette Michigan. Obviously a lepturine.

Trigonarthrus minnesotanus (Casy). Based upon the amount of black on the apex of the elytra.

I can't find this name in any book I have or online. Is it perhaps spelled wrong? Or maybe it's a new name replacing an old one?

Try 'Trigonarthris' for the genus and you will find it..  . It is for sure a female Trigonarthris.Now for the species I'm not sure if it is minnesotana or proxima. Thanos |

Source. My collection, and Dougals Yanega's Field Guide to the Northeastern Longhorned Beetles (Coleoptera: Cerambycidae.) Also, Linsley and Chemsak, Longhorned Beetels of North America, Lepturinae Pt 2. Or, The Cerambycidae of the Western Hemisphere, I placed the url in the old forum aobut 2 years ago.

Greetings,
Easy one to verify - check the underside of the last segment of the abdomen (last abdominal sternite) - if it is entire (smooth, no grooves) it is T. minnesotana; if it has a notch (emargination) in the end, it is T. proxima.
Cheers!
