Hi Jonathan..this is a bit late of a reply..the above characters best distinguish A. striata from A. insolens (together with A. insolens having a broader and less tapered body shape).
To distinguish A. lecontei from A. insolens, look for a carina on the 5th elytral interval- if it's there it's lecontei. A. lecontei also has the elytra with a relatively flat area medially and a concave area on each side.
