The rcsiMnhhiiici' of this earwig to the s|)ecit's of the Xeo- 

 tropical genus Neolobophoru is really extraordinary, l>ut, 

 apart from the generic characters given above, the locality is 

 enough to distinguish them ; even the pygidiutn and force[).s 

 are strikingly similar.

The genus Sphingolahis has had a cheqiieriHl history. 

 Erected in 188li l)y de liornians for Sphinffolahis furcifera, 

 Borm., from Sumatra, it was wrongly assumed by that author 

 and by most others to coincide with Apteryijida, Westw. : 

 that is to say, to remove from the old genus Forjicula all 

 those species in which the forceps of tiie male woro not diluted 

 8troni;ly near the base — that is to say, Dohrn'.s Group 1. of 

 Forjicula. 



Discussing the genus in a later work, (L894) p. 406, 

 de Bormans writes : — " Sauf eo caract^re [/. e. the ibrm of 

 the forceps] il ne diffire en r'wn du geiu'c Forjicula . . . par 

 cons«5(juent, il est malheurcusement impossible do savoir si 

 uno fVmelle \ao\6q. appartient k Pun ou i\ I'autre de ces deux 

 genres." And he adds : — " Lc genre Sphingolabis a pour 

 type europden Sph.albipennis^ ^i^'o'» Charp. " ; and further : 

 " il renferme parmi lea o.xotiques : Sph. tieniata, Dohrn, 

 percheroui, Gucr., adifornica^ Dohrn, serrata, Serv., lutei- 

 jiennis, Serv., aruc/tidis, Yers.,^ <C(i//aci/, Dohrn." 



In those days it was not recognized that the above species 

 forms a deeidrdly hcterogenccms group. In (I.SSJ9) p. 2^)3, I 

 showed that if wo regarded y'urt//"«/(i, Borm., and alOiptnnis^
