Distribution. — Diyatalawa, Madulsima, Assam. ^ "^ _^~ 



Since my original description of this species I have found it 

 commonly in three distinct localities akmg 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 Alucitinte 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.

 1-j beyond cleft . . . . fasciola

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.
