Translation by Sherlock:

Marilia mixta HAG.
? Molanna mixta HAGEN 1858, Verh. Zool. Bot. Ges. Wien 8, p. 485-486
(Rambodde).
Marilia ceylanica MARTYNOV 1936, Rec. Ind. Mus. 38, p. 248-249, fig. 10-11
(Peradeniya).
I do not have a proof that Molanna mixta HAG. is the species of Marilia of which it sagit here. But I regard that as very probable, the description of HAGEN corresponding very well to the insects and the family of Molannides missing apparently of Ceylon. This species is not rare along the agitated rivers, on average altitude, at the output of the mountains.
