Sub-family 1—CHELIDURIN J. 
This sub-family has been rearranged by Verhoeff (Zool. 
Anzeiger, 1902, p. 187), He removed those species with 
free but rudimentary elytra to the Anechurinx, under the 
name of Pseudochelidura, and the remainder he subdivided 
into three genera based on the shape of the abdomen, 
namely, Chelidura, Mesochelidura and Chelidurella. Nothing 
has been added to our knowledge of these genera since 
that date. 
Sub-family 2.—ANHCHURIN 4. 
This group was first separated from the other genera of 
the Forficulidx, sensu stricto, by Verhoeff, but he discrimni- 
ated Allodahlia, for which, quite unnecessarily, he erected
