This beetle appears to be uncommon. Even though it was described a year before Charles Darwin (1809–1882) was born, the specimen photo posted here appears to be the first photograph posted to the Internet.
Blatchley (1910), in his 1385 page tome on the beetles of Indiana listed only one county (in northeastern IL) and date (July 30) for the species and stated that it was rare. (4).
Blatchley (1924a, 1924b), after extensive field surveys and collection inspections listed only two locations for Florida.
Brimley (1938) lists 2959 species of beetles (and 9566 species of insects total) for North Carolina, but C. trivittata is not among those listed.
White (1968) reported only one specimen from Texas (College Station) which he wrote might be in error. (Note that the specimen posted here confirms the record that White doubted.
Balsbaugh & Hays (1972) reported five specimens from three counties, up from one county reported by Loding (1945) (6)
Cavey (2004) reported only two specimens known to him from Maryland.
Ciegler (2007), in addition to her own field surveys, examined the specimens in 10 entomological collections (including the USNM) but only found eight collection localities for South Carolina.

Clark et al. (2004), in their extensive review of North American chrysomelid literature, list only two references (90 years apart) concerning the host plants of C. trivittatus, namely Blatchley (1910) and Clark (2000).
