The student is referred to my papers on the Bombycidæ of cuba for remarks on a generic group closely allied to Halisidota (Halesidota) which I have called Euhalisidota, describing under it the species luxa, fasciata, scripta and alternata. Closely allied to the first of these is a species from Florida, the male of which I have from Mr. Schwarz, the female from Mr. Dury. It is hardly so large, and without the black thoracic marks, although I can make out two black points on the collar in one specimen. It seems to differ by the streak of dusky speckles about the median vein at the extremity of the cell, and the distinct subterminal series of isolated black dots. The color is dusky ochre, with the thorax darker and the inside of the fore tibiæ orange. The male antennæ are bipectinate. The secondaries are paler, with a slight apical mark in the male.
