major Allied to C. fumidus var. fragilis Pergande, but differing in the following characters: The head is shaped as in the vars. illitus and festinatus and is distinctly broader than in fragilis and bears on the vertex a dark brown spot which is absent in this variety. The yellow color of the body and especially of the head is darker and more reddish, and the brown bands on the gaster are darker and more sharply defined. The suberect hairs on the antennal scapes are about equally abundant in both varieties, the hairs on the body are more abundant in imbecillus.

minor Indistinguishable from the corresponding phase of fragilis.
