Bob, Thanks for the verification and you did mention this earlier so thanks for your level of detail...so many of them look so similar. Sounds like your wife had a keen interest and knowledge in this area I bet her collection was beautiful with all those specimens, your generously sharing with the museum in Denver I’m sure they were thrilled....collections like your families don’t come to them everyday. Thank you for the clarification and sharing the distinctions with us all....I went and looked again with my reading glasses :) . I can see what the distinctions you are describing.
