observations on seven species of Limnophila and two ‚Poecilostolae 
published by Mr. Beling in the Verh. Z. B. Ges. 1873, 1878 and 1886. 
Rondani proposes the name Limnomya for Limnophila which 
is preoccupied (Mollusca 1828). The lesser evil between the two will 
be, I think, to retain Limnophila which has been in use for more 
than half a century.

Gynoplistia is a Limnophila with pectinate antennae, peculiar 
to Australia, New Zealand, New Guinea and the adjacent islands 
(Salwatty, Aru, Mysol) and Celebes. The genus has not been found 
west of Wallace’s line of division between the Austro-Malayan and 
Indo-Malayan Archipelago's. 
The species of Gynoplistia seem to be numerous, but are poorly 
represented in collections and, for this reason, have been but little 
studied. The original definitions by Westwood and Macquart must 
be modified, so as to admit within the genus several newly discovered 
species, differing in characters that are not essentially generic. 
The number of joints of the antennae varies; usually there are 
between 16 and 20. The joints of the flagellum emit a single branch 
each; the number of branched joints, in the species which I have 
seen, varies from twelve to seventeen, beginning with the first 
joint of the flagellum; the terminal joints (three, four or five in 
number) have no branches. The branches in the female are generally 
shorter, sometimes also they are less in number than in the male. 
G. jucunda O. S. from Celebes has only the joints from three to 
eight (3—8) branched in both sexes. The three first branches in all 
the species are inserted more sideways, and hence are pointing in a 
direction different from that of the others.
