Explanation of Names
Cryptocephalus atrofasciatus Jacoby 1880
atrofasciatus (L). 'black-banded' (1)
5.0-7.5 mm (2)
Elytra: Usually yellow or orange with three transverse, generally distinct, undulating orange, red, or (usually) black bands. When bands black, these sometimes expanded and partly to largely confluent, elytra thus sometimes predominantly black with vague to distinct elongate yellow spots. (2)
This species is one of the most variable in the genus in coloration. Continuous intermediates exist between the one extreme in which the elytra are yellow with rather vague orange bands and the other in which the elytra are almost entirely black. The extreme forms are few. (2)
