Doug Yanega on distinguishing C. subargentata from the dark form of C. haematites: The dark form of haematites is a fairly common and universally overlooked morph found across n. NA: in Canada, the upper tier of the US, and at very high altitudes elsewhere. Once I learned to ignore the pronotal color, and look at the hairs on the pronotum and elytra instead (dark in subargentata, pale in haematites), everything became easier. Specimens of subargentata with very definitely dark elytral hairs occur all the way across, so I don't think there's a geographic variant of subargentata that has pale elytral hairs. I think there are a lot of misidentified haematites specimens sitting in collections. (pers. comm. to =v= 31.v.2012)
