Genus 5.—ELAUNON.* 
Cum genere precedenti congruet, sed, abdomen distincte depres- 
sum, parallelum, haud cylindricum ; forcipis bracchia ¢ basi ipso 
subdilatata atque intus dentata, 
This genus is for Apterygida bipartita, Kirby, which 
approaches true Forficula and Apterygida, but the fourth 
segment of the antenne is not sufficiently short to justify 
its being placed in the latter genus, and the dilatation of 
the forceps at the base is only incipient, being emphasised 
by the flattened triangular tooth there, so that the resem- 
blance to the typical Yorficula forceps is more apparent 
than real; but in the form of the abdomen and _ body 
generally, it is nearer to that group than to Hparchus. 
The type is Sphingolabis bipartita, Kirby, Linn. Soc. 
Journ. Zool., xxiii, p. 526 (1891), from India and Ceylon.

I have separated into this group those species of Apte- 
rygida with a sharp, pointed or spiny pygidium ; they all
