This long list of synonyms which is temporarily adopted from Meyrick 
and Fletcher appears to us to be open to doubt. However, we have no 
sufficient material of this genus from other regions needed for a revision 
of all the above names, and are compelled to restrict ourselves to a few 
preliminary remarks. 
In the first place we are inclined to remove the three last named genera, 
viz. Erechthias, Callixestis and Thalerosloma from the above list of syno- 
nyms of Limnaecia, as these are recorded to be in the possession of a 
“slight pecten” on the basal segment of the antenna, which important 
feature is entirely absent in the material at hand. 
Furthermore, our material can easily be divided into two groups : those 
with a decadent neuration of the fore wing: with the cell and the basal 
parts of the veins originating from it, becoming entirely obliterate 
towards the upper angle of the cell (section 1); and those w r ith a normal 
neuration of the fore wing, with the cell closed and all the present veins 
clearly traceable, which must be the original situation (section 2). What 
by superficial investigation might appear an incidental anomaly of the 
typical Limnaecia neuration (cf. below), is actually a constant character 
persisting with great uniformity in all the species concerned, notwith- 
standing considerable variability of their superficial appearance. The 
peculiar and interesting character ol very long lateral expansible pencils 
of hairs in the male sex of the species of the section 1, originating from the 
metapleurae and often reaching beyond the middle of the abdomen, is 
also constant. We could find references to this character of the following 
species, which may be included in our “section 1” also: Limnaecia cybo-
