256 Mr. R. M‘Lachlan’s Descriptions of 
alis posticis ochraceo-hyalinis, venis fuscis; pedibus ochra- 
ccis. (Mas?.) 
Long. antenn. 20 lin. ; corp. ?; exp. alar. 17 lin. 
Habitat apud Sarawak, in insula Borneo (Wallace). 
In Mus. Saundersiano. 
Antennz pale ochreous, all the articulations narrowly ringed 
with black. Head and thorax ochreous. Palpi greyish-ochre- 
ous. Anterior wings pale ochreous, the costal margin and the 
neuration bright ochreous. Posterior wings hyaline, thinly 
clothed with ochreous pubescence ; neuration fuscescent. Legs 
ochreous. 
Genus NoTanaTOoLica, nov. gen. 
Antenne graciliores, alis fere triplo longiores, in g quam in 
 longiores. Palpi maxillares hirsutiores ; articulis 1° et 
4° longis, fere aqualibus; 2°, 3° et 5° zqualibus et singulis 
4° duplo longioribus. Ale anticee elongate, angustz, sparse 
pilosee ; marginibus costali et dorsali fere parallelis ; cellula 
discoidali occlusa; ramulo superiore rami thyriferi ¢ fur- 
cato, ¢ bifurcato; alze posticze late, anterioribus breviores, 
subtriangulares. Pedes longi. Calearia 2-2-2. Abdomen 
robustum, in @ subdepressum. Appendices inferiores in ¢ 
bisarticulate. (Mas et Foem.) 
Antenne nearly thrice the length of the wings, longer in the 
male than in the female, very fine; basal joint swollen, scarcely 
so long as the head. Head transverse, hairy. Maxillary palpi 
very hairy; the first and fourth joints moderately Jong, nearly 
equal; the second, third and fifth equal, each about thrice the 
length of the fourth. Mesothorax long, the sides nearly parallel. 
Anterior wings very long and narrow, slightly hairy, most so in 
the female; costal and dorsal margins nearly parallel, the apex 
slightly dilated and elliptical; neuration strong; discoidal cell 
closed, dilated and angular at the apical end; in the female there 
is one more apical cell than in the male, owing to the upper branch 
of the superior branch of the ramus thyrifer being twice forked 
in that sex, and only simply forked in the male; the radius is 
united to the discoidal cell by a transverse vein; another trans- 
verse vein unites the discoidal cell to the ccllula thyridii; and 
there are three others placed nearly in a straight line below it, 
one of them closing the cell. Posterior wings broad, subtrian- 
gular, shorter than the anterior; neuration alike in both sexes ;
