are present in the fore wings, I and 5 in the hind wings; there -is no 

 cross-vein in the hind wings; antennae much longer than the body, 

 basal joint very large. Based on a tiny insect, no larger than a good- 

 sized hydroptilid, which differs from all other Leptoceridae in the 

 greatly reduced venation of the hind wings. 



Type: The following species. 



Setodina parva, n. sp. (PL IX, figs. 24, 26). 



A uniform dull pale gray; legs and antennae more yellowish; wings 

 clothed with gray hairs. Fore wings quite slender; the radius and 

 subcosta close together; the discal cell longer than second apical cell; 

 the cross-veins are very faint, but can be seen against a strong light; 

 hind wings with a long fringe behind, no cross-veins present; in the 

 basal part of third apical cell of the fore wings there is a small dark dot. 



Expanse, 5.5 mm. 



Three specimens from Kissimmee, Fla., in November. 



Hydropsyche minuscula n. sp. (PL VIII, fig. 5). 



Dull black, head and thorax clothed with yellowish gray hair, almost 

 golden on vertex, with some black hair each side; antennae pale, annu 

 late with dark; abdomen blackish above, yellowish below; legs yel 

 lowish, with yellow spurs, some longer black hair on hind tibiae. Wings 

 clothed with black and yellowish hair, giving them a uniform grayish 

 or brownish appearance, devoid of markings, except sometimes a little 

 more heavily marked with black on the middle of the hind margin, and 

 sometimes a faint yellowish mark near outer anal angle ; fringe blackish, 

 or broken with yellow near outer anal angle; hind wings gray, with 

 gray fringe. Eyes of male widely separated; antennae rather heavy; 

 fore wings broadly rounded at tips, fork i reaching more than one- 

 half way to discal cell; in hind wings fork I is absent, and the tip 

 is slightly upturned. 



Length, 6 mm. 



Several specimens from Plummers Island, Maryland, in 

 August. 



It falls in Ulmer's genus Hydropsychodes, which differs from 

 Hydropsyche only in lacking fork I to hind wings ; H. analis, 

 H. sordida, H. gradlis, and H. divisa will also go in this genus, 

 if it be adopted. 



Phylocentropus, n. gen. 



An hydropsychid near Holocentropus ; venation as in that genus ex 

 cept that fork i in both wings arises from the discal cell; in this
