99 Melanotis caerulecens Oct. 22 El Batel, 5100 feet, Sinaloa Present in dense, tall growths along the steep draws or in understory thickets where the forest is more or less undisturbed and fairly luxuriant, as on the north face of the ridge above camp. The species is exceedingly wary. Here it probably occurs along the upper margin of its altitudinal range, as it is mainly a [illegible] species of the lower, tropical zones.
