extends fully to middle of discal cell (on outer third in G. pilosa); fork 
3 has a shorter pedicel than in that species. The comb on venter of male 
has five teeth each side, and the middle one is not much longer than the 
others; the male genitalia also differ. 
Expanse 18 mm. 
Two males from Kawana, Japan, 25 June. 
Crunoecia albicornis n. sp. 
Head black, with tufts of long black hair above eyes; antennae black, 
on basal joint with long erect black hair all around, beyond this joint 
the antennae are nearly white, the first few joints marked with black; 
palpi pale brown; thorax black, with some tufts of black hair in front; 
abdomen dark brown; legs pale brown, almost white on tarsi; wings 
blackish, with long black hairs, and short, yellowish appressed hairs, 
fringe blackish, with two or three white patches on outer part, hind wings 
blackish, with some short yellowish hair, fringe long, some white spaces 
in it between ends of veins. Structure, in general, similarto the other 
species; spurs 2-4-4; basal joint of antennae very long and slendar and 
densely clothed with long hair, no cilia on thread of antennae; maxillary 
palpi small and slender, pendant. Wings with forks i, 2, 3, 5; discal 
cell longer than the pedicel, but fork i extends only a little way on it, 
fork 3 reaches anastomosis, but not farther, the cross-vein connecting 
cubital and anal is before middle of discal cell; in both wings the cross- 
vein at base of the fourth apical cell is hyaline white. 
Expanse 20 mm. 
Two specimens from Hikosan, Buzen, Japan, 28 April. 
Perissoneura similis n. sp. 
Jet black; front and middle legs nearly white, hind pair darker; male 
with a large white spot in each wing beyond the anastomosis, elongate 
and bent outwards, the inner side distinct, but outer edge ragged and 
fading out, the one in fore wing has the inner side angulate, the one 
in hind wings has the upper part of inner side concave ; female with wings 
entirely black, except faint small whitish spot in base of second and 
fourth apical cells, and on the thyridium, in the hind wing a small spot 
in base of fourth apical cell. Wings shaped about as figured for P. para- 
doxa McLach. or a trifle more elongate; the costal cross- veinlets are 
present, but the discal cell is longer, the apical cells rather shorter, the 
anastomosis more regular, and fork 4 is absent in both sexes. 
Expanse, d\ 46 mm., 9 5 mm. 
Two males and one female, from Hikosan, Buzen, 29 May, 
and Tsuno, Buzen, Japan, 8 May.

Similar in most respects to P. similis, it differs in shorter and more 
rounded wings, the white spots of male are broader, not so elongate,
