THE EARWIGS OF CEYLON. 319 



This is another cosmopolitan species, originating almost certainly from the 

 Mediterranean Subregion. I have received Dumerous examples taken in 

 Ceylon by Mr, Green, and it is common also in India and in Burmah, It 

 occurs in fact in all tropical districts, where it has been spread by shipping.

 ANISOLABIS, Fieb, 



Body long and slender. Colour black, shining, varied with testaceous or 

 reddish. Antennse with about 20 segments, first and third tarsal segments of 

 about equal length. Elytra entirely absent or represented by barely distin- 

 guishable rudiments. Wings entirely absent. Lateral plications of the 

 abdominal absent or very faint. Forceps short, stout, in the $, often strongly 

 curved in, semicircular, with right branch more strongly curved than the 

 left, or conical, strongly arcuate, pointed, not toothed ; in the 9 the branches 

 are contiguous, simple, conical. 



AnisolaUs, Fiebr., 1853, Lotos,, iii., 257. 



This genus may be recognised by its shining black or very dark brown 

 colour, total absence of organs of flight and simple forceps. The feet are 

 usually testaceous, sometimes varied with black bands ; the antennae often have 

 white rings, but this is a very variable and unstable character. 



de Borinans retains Brachylahis, Dohrn, for B. punctata, Dubr,, and B. 

 chilerish, Blanch, 



Dohrn's names, Forcinella and Brachylahis, fall before the prior AnisolaUs,
