9. Semiocosma, Meyr. 
Head with appressed scales, sidetufts large, loosely appressed. Antenne 
in male stout, very shortly ciliated (+), basal joint moderate, without pecten. 
Palpi moderately long, second joint not exceeding base of antenne, 
thickened with dense scales, somewhat loose beneath, terminal joint rather 
shorter than second, slender, recurved, with a tooth of erect scales in 
middle on posterior surface. Thorax smooth.  Forewings elongate, 
moderate, apex rounded, hindmargin almost straight, oblique; surface with 
tufts of raised scales. Hindwings as broad as forewings, elongate-trape- 
zoidal, hindmargin faintly sinuate, cilia 4. Abdomen moderate, slightly 
flattened, distinctly margined. Middle tibie with a median whorl of pro- 
jecting hairs, roughly short-haired beneath ; posterior tibis with moderate 
dense somewhat appressed hairs above. Forewings with vein 7 to costa, 2 
from considerably before angle of cell. Hindwings with vein 5 bent and 
approximated to 4 at base. 
Not nearly allied to any New Zealand genus except Aochleta, and distin- 
guished from all genera of the family, except the South American Gonionota, 
by the median tooth of scales on the terminal joint of the palpi; from 
Gonionota, which possesses similar palpi and also tufts of scales on the 
surface of the forewings, and is doubtless nearly related, it may be separated 
by the smooth thorax (in Gonionota the thorax is crested), and probably by 
other points, but Zeller’s description of the genus is given in so little detail, 
that they cannot be stated. There can also be little doubt that the genus 
has some true affinity with the European Psecadia. 
The genus is confined to New Zealand; I have five species, of which 
the folowing is a tabulation :—
