216 NATHAN BANKS. 



CEcetina flavida n. sp.— Yellowish, head, thorax and palpi clothed with 

 pale grayish hair; fore wings quite densely clothed with short yellow hair and 

 with gray fringes, anastomosis only a little infuseated, foj-e wings long and acute, 

 discal cell only a little way heyond thyridial cell, the anastomosis being almost 

 continuous and oblique, thyridial cell almost one-half longer than discal cell, the 

 fifth apical cell not extending upon the thyridial cell. Expan.se 16 mm. 



Kissimmee, Florida, November. 



Separated from CE. incertn by yellowish fore wings, with less 

 distinct and more continuous anastomosis, and the longer thyridial 

 cell. 



<Ecetina fiiinosa n. sp. — Head and thorax brown, with gray hair; an- 

 tennae pale, annulate with black; legs luteous, first pair darker; palpi brown, 

 with gray hair; abdomen greenish; wings more densely clothed than other spe- 

 cies with black hair, anastomosis black, and usually with three black spots, one 

 at base of discal cell (always present), one at base of thyridial cell, and one in 

 middle of hind margin of thyridial cell, the basal half of the radius is usually 

 black, fringes gray; tip of hind wings slightly fumose. Fore wings not very 

 acute at tip, the discal extends quite a little beyond the thyridial cell, but the 

 latter is more than one-half longer than discal cell, the fifth apical extends quite 

 a ways on the thyridial cell (much farther than in other species). Expanse 17 mm. 



Washington, District of Columbia, July, August. 



<Ecetiiia floridana n. sp. — Grayish ; antennpe rather paler, annulate with 

 brown at tips of the joints, much more than twice the length of the wings, basal 

 joint clothed with white hair; legs yellowish gray, spurs 1-2-2; fore wings very 

 long and slender, acute at tips, hinder pair bi-oader and much shorter, fore pair 

 clothed with yellowish gray hair, and some white and black hairs along the 

 veins, three indistinct whitish spots on the posterior apical margin, posterior 

 margin with a fringe of yellowish gray and black hairs, all the apical cells reach 

 the anastomosis, and are of suhequal width at base, except the first which is 

 acute, fifth apical extends a little way on thyridial, hind wings scantily 

 clothed with yellowish hair, and a rather long yellowish gray fringe, fork five 

 present in hind wings, as well as three in front of it, first apical cell extending 

 back on the discal. In the % genitalia there is a large median corneous piece, 

 deflexed rather beyond its middle, and acute at tip. Expanse 19 mm. 



Biscayne, Bay, Florida (Mrs. A. T. Slosson). 

 HYDROPSYCHIDJE. 



Hydropsyclie gracilis n. sp. — Head blackish, face with whitish hair: 

 basal joint of antennae brown, rest pale yellowish, obliquely and faintly annulate 

 with brown ; palpi brown ; legs pale yellowish ; thorax and abdomen dark 

 brown ; wings gray hyaline, with gray hairs and gray and black fringe, the 

 black mostly at ends of veins. Fore wings rather long and slender, apex 

 rounded, venation as usual, the discal cell less than one-third the length of the 

 apical cell beyond it; hind wings rather short, not very broad, but broader than 

 fore pair, broadest in the middle, the first and second forks are near the outer
