maxillary palpi are very long, the second joint plainly longer and thicker 
than the third; labial palpi short, slender (not as long as in N. ruficolle). 
Wings rather broad, broader than in N. ruficolle, venation similar to that 
species, but the discal cell is a little longer, and the radial sector a trifle 
more bent at the pterostigma. 
Expanse 34 mm. 
One specimen from Gifu, Japan. 
Moropsyche n. gen. 
A Limnephilid ; maxillary palpi of male slender, second and third joints 
subequal; vertex elevated transversely in the middle, the black ocelli at 
sides of this elevation; basal joint of antennae not very long; prothorax 
short; spurs 1-3-4; fore-wings rather narrow, subcosta running into 
costa, discal cell short, vein closing it weak, forks i, 2, 3, and 5 present, 
fork i not reaching the discal cell, the pedicel about one-half the length 
of fork, fork 3 almost reaching the anastomosis, median sector arising 
just a little before the anastomosis, so that the arculus is as far out as 
anastomosis; in hind wings the discal cell is open, fork i very short, with 
long pedicel, forks 2 and 3 acute at base, latter not reaching the cross- 
vein. 
Type: M. parvula Bks. 
Moropsyche parvula n. sp. 
Black, some yellow hairs on face, and near base of antennas; legs pale,

Wings blackish, or fumose, sparsely black haired, and with much appressed 
yellow hair; antennae distinctly crenulate within. Wings narrow, rather 
rounded at tips, venation rather fine. 
Expanse 12 mm. 
Two males from Hikosan, Buzen, Japan, 28 March. 
Brachycentrus vernalis n. sp.

lobes; abdomen black, with a few black hairs; legs black on coxae and 
femora, paler beyond, especially on hind pair, which are clothed with

Gcera japonica n. sp. 
Similar in size and general structure to G. pilosa, but paler yellow 
throughout; the swollen area in the front wings at end of the "area 
interclavialis " is not near as large as in G. pilosa; the fork of front wings
