PLUME-MOTHS OF CEYLON. 
31 
Trichoptilus paludicola, Fletcher. 
(Plate A., figure 7.) 
Spol. Zeylan., V., 20 (figs.). 
Distribution. —Diyatalawa, Madulsima, Assam. 
Since my original description of this species I have found it 
commonly in three distinct localities along the Madulsima range of 
hills; larvae, pupae, and imagines being found together during May 
and August. It will probably be found to be widely distributed at 
an elevation of about 4,000 feet, but is of course confined to damp 
places where Drosera grows. 
Early Stages. —These are described in the reference quoted. 
DIACROTRICHA, Zell. 
* (Cosmoclostis , Meyr.) 
These little moths seem to approach the Alucitince very closely 
in some respects ; the single nervure in third segment of hind wing 
and the single spina of the ? frenulum, however, will serve to 
show their real affinities with the Platyptilince. It appears to me 
doubtful whether D. fasciola is really congeneric with aglaodesma 
and its allies (auxileuca, pesseuta, and quadriquadra) , for which 
latter group the name Cosmoclostis may be retained, but in consider¬ 
ing a small local fauna it seems inexpedient to multiply genera more 
than absolutely necessary.'

Diacrotricha fasciola, Zell, 
(Plate A., figure 6.) 
Fasciola.— Zeller, Linn. Ent., VI., 399 ; Meyr., T. E. S., 1907, 471, 
Callimeres. —Meyr., M. S. (ined.). 
Distribution. —Galle, Kandy, Badulla, Arawa. 
Probably widely distributed in the wetter districts where bilimbi 
trees are cultivated. 
Outside of Ceylon this species has been recorded from India, 
Java, and the Kei Islands.
