Trichoptilus pelias* Meyr. 
T. E. S., 1907, 472. 
Distribution. —Originally described from Coorg and Assam. 
Not previously recorded from Ceylon, but my collection contains 
four examples which agree with the rdiagnosis of the type. They 
were taken :— 
(а) Nalanda; October 30, 1906. Amongst grass, &c., by the 
roadside. 
(б) Trincomalee ; November 11, 1906. Oopah estate (E. E. 
Green), at light. 
(c) Trincomalee ; November 15, 1906. Powder Island. 
(d) Colombo ; December 17, 1906. Mutwal. 
- It is noteworthy that all the above specimens were taken in the 
low-country, whilst Mr. Meyrick’s Indian examples were found at a 
considerable elevation. 
Early Stages. —Unknown.
