Chlamydatus ruficornis Knight, 1959: 424 (n.sp.).

DIAGNOSIS: Distinguished from all other Chlamydatus spp. by the following combination of characters: the slate gray coloration, the red appendages, the fusiform antennal segment 2, the frequent brachyptery (fig. 2) with the males rarely being macropterous, and the entirely dull vertex and face.

HOSTS: None recorded.

DISTRIBUTION: Plains region of North America.

DISCUSSION: Knight (1959) and Kelton (1965) treated C. ruficornis as always brachypterous with truncate hemelytra. We have examined a male specimen from Colorado that is fully macropterous (fig. 2); it was taken with a series of brachypterous females on prostrate vegetation in a waste area. Macropterous males are now known from Alberta.
