It was constantly met prowling about under rocks, often with its body coated with mud and refuse, as if for conceal- ment. Its eyes are in a cluster on each side of the head, but are not conspicuous in the large larvae because of the dark hue of the whole animal. Younger larvae presumed to be this have the head and first body division reddish brown, marked with black, and the black eye-specks are con- spicuous, forming a cluster on each side of the head, one of them occupying the center, the rest ranged in a curved series about it, the ventral median one smaller than the rest. The smallest larva of the family collected is white, and the branched respiratory structures of the abdominal somites, consist of a basal piece and several simple branches, as in some of the case-fly larvae described. Possibly it is a differ- ent species. It was taken in the Left Fork of Straight Creek, September 1, 1911. EPHEMERIDA (MAY FLIES).
