If, confining myself to Coleoptera found by Prof. Townsend or myself near Brownsville, I mention the genera Agra, Dasydactylus, Physorhinus, Achryson, Gnaphalodes, Amphionycha, Megascelis, Plectrotetra, Brachycoryna, Listronychus, Polypria (quite a number of others are not yet determined, or undescribed), no one can deny the existence of a semi-tropical insect fauna along the north bank of the lower Rio Grande.
