EXOTIC MICROLEPIDOPTERA. 
Depressaria triallactis, n. sp. 
2 . 20 mm. Head,. palpi, thorax pale greyish-ochrous. Pore- 
wings very elongate, slightly dilated, costa slightly arched, apex 
obtuse, termen obliquely rounded; 2 and 3 stalked • pale greyish- 
ochreous with very faint pinkish tinge; a small indistinct blackish 
dot at base of dorsum; stigmata black, first discal minute or 
obsolete but additional dot obliquely above and before it well- 
marked and rather obliquely before plical; five small indistinct 
blackish marginal dots on apex and termen: cilia pale greyish- 
ochreous. Hindwings light grey, veins and terminal edge darker; 
cilia pale grey, a rather darker basal shade. 
Morocco, Rabat, bred April from larvae feeding on Foeniculum 
( Umbelliferce) (Rungs); 1 ex. 
CARPOSIN1DJE. 
COMMATARCHA, n. g. 
Head with appressed scales ; ocelli posterior; tongue developed. 
Antennae |, filiform, scape moderate, rather stout. Labial palpi 
moderate, slightly curved, subascending, with appressed scales, 
terminal joint shorter than second, pointed. Maxillary palpi 
absent. Hind tibiae loosely scaled above. Porewings with tufts of 
scales; 2 from angle, 2-5 approximated at base, 6 remote, 7 
parallel, to termen, 8 and 9 approximated at base, 10 remote, 11 
from middle. Hindwings 1, trapezoidal-ovate, cilia -|; with 
cubital pecten; 2 from |, 3 and 4 short-stalked, 5 absent, 6 well- 
developed, 6 and 7 parallel. 
Very primitive, having the fully-developed vein 6 of hindwings 
only found elsewhere in Sosineurct, which is otherwise more 
specialised. 
Commatarcha palaeosema, n. sp. 
2 . 13 mm. Head fuscous, face whitish. Palpi, thorax dark 
grey, teguke lighter. Porewings rather elongate, posteriorly dilated, 
costa gently arched, apex obtuse, termen obliquely rounded; 
fuscous irregularly mixed dark fuscous, base of scales whitish ; 
a white spot on costa before 5, nearly confluent with a smaller 
spot beyond it beneath costa; two or three variable whitish spots 
edged dark grey in middle of disc; five dark grey raised marks 
edged whitish posteriorly on costa from before middle to apex ; dark 
grey tufts edged white posteriorly above fold before and beyond 
middle of wing; a large dark grey tuft edged posteriorly with a 
conspicuous rather oblique hooked white mark in disc at §; a curved 
subterminal shade of black irroration rather near and parallel to 
apex and termen: cilia grey with traces of darker bars. Hind¬ 
wings and cilia pale fuscous. 
Japax (Konsyu), Kyoto, April (K . TaJceuchi); 1 ex. It is 
extremely interesting to find this primitive species displaying con¬ 
spicuously the characteristic C-shaped white discal mark of Bondia.
