Physical descriptionA common insect in Mexico and varying in colour of the vestiture—white, cinereous, brownish or olivacious—and in the development of the black markings on the prothorax and elytra. The following forms may be noted:
Mr. Wickham informs us that he has taken this species in abundance at Rio Balsas, freshly emerged, in the early part of August, upon various bushes on the face of the mountain just across the river from the village. Amongst the eighty-two specimens examined by me, two only belong to var. α, eighteen to var. β, and three to var. δ, the true C. modestus (= var. γ) being represented by a long series, and the var. viridans (= var. ε) by numerous examples, including three from the Sturm collection. The male (of both C. modestus and C. viridans) has the penis-sheath broad and truncated at the apex (figg. 13 a, b). The length varies from 12—20 mm. The types of Gyllenhal and Boheman were examined some years ago by Dr. Sharp.
