Gordon's Figures
Head with broad, [b]pale band between eyes;
anterior pronotal margin entirely pale
elytral suture narrowly blackish
elytra with or without spots(1)
The spotless form of C. novemnotata may be confused with the bandless form of C. trifasciata subversa. Click on thumbnail for details.

C. californica
Range
Current range(2) vs historical range (1)
Populations suddenly declined and disappeared from the Northeast in the 1980s. Almost extirpated in the East (Cornell University).
Remarks
In 1985, Gordon called this sp. "...extremely widespread in North America and is commonly collected"(1) --now about one new record is reported to BugGuide annually. New York State considers C. novemnotata to be a Species of Greatest Conservation Need(3)
