Ground color pale flesh tint, tinged with yellow (more yellowish in the female) marked, mottled and dotted with brown; antennae, legs and setae white. Head pale brownish, with whitish margins; in the male, occupied superiorly by the large turbinate superior portion of the compound eyes, which are pale egg-yellow on their superior, faceted surface, with paler margins, and which are as large as all the remainder of the head; in the female the top of the head is very flat, and is traversed by two longitudinal, irregular, pale brown bauds, which are surrounded and separated by whitish. Prothorax paler, thickly dotted with brownish color. Dorsum of the mesothorax with a pale, longitudinal median suture, each. Fig. 1 Wings oJ Callibaetis skokiana, male side of which is a band of brown rounded off posteriorly, and at the sides there are brown spots inferiorly. The median narrow pale line is continued posteriorly to the abdomen, and there are brown spots on the sides of the metanotum. Sides of thorax irregularly speckled with brown. Legs white with darker mark- ings at the knees and at the ends of the tarsal segments, the last one of which is wholly washed with brown. Wings with the usual costal band, differing in the sexes, behind which they are hyaline. The band in the female is darker and better de- veloped. It covers proximally the bases of all the veins and is regularly narrowed to the apex, ending just before the apex of the wing, not lobed posteriorly, fenestrate with hyaline on most of the cross veins except toward the base, and reduced to a yel- lowish wash in the stigmatic region and aJbout the humeral cr
