THiE^ EARWIGS OF CEYLON. 335 



I include this species on the list on the strength of a female in very bad 

 condition in the Hope Collection. I refer it to this species, which is other- 

 wise unknown to me. It may be a variety of O. dux, Borm,, also from 

 Burmah. 



OPISTHOCOSMIA CEYLON IC A (Motsch.) 



Small, slender, brown. Antennae 12-segmentate, brown. Pronotum nar- 

 rower thaa the head, hinder border rounded, anterior border straight, the 

 sides strongly turned, shining brown. Elytra twice as long as the pronotum, 

 uniform brown, truncate at the apex. Wings projecting well beyond the 

 elytra, brown, with a faint yellow spot on the outer side at the basis and at 

 the apex at the suture. Abdomen darker-brown, the glandular folds very 

 prominent, black. In the $ the antepenultimate segment is armed on each 

 side with a short tooth, the. penultimate and ultimate segments are narrow- 

 ed, the latter with a deep impression in the middle, the penultimate ventral 

 segment semi- circular, covering only half the last segment. The forceps are 

 long, with the branches contiguous at the base, parallel, then curved moder- 

 ately outwards, incurved to meet at the apex, flat beneath, above with a long 

 narrow, crest-shaped lump near the base, in the middle with two teeth, the 

 first fairly long, the second shorter. In the $ the abdomen is simple, 

 narrowed posteriorly, unarmed, the penultimate ventral segment as in the 

 male, the forceps with the branches slender, straight, contiguous, crossing 

 at the apex. The sternum and feet are paler than the abdomen, the latter 

 very long and slender, the first tarsal segment as long as the third. The 

 whole body is shining, only the antenuEe, feet, underside of the body and 

 the forceps of the $ pubescent,

I only know the female of this species, and so have taken the description 

 of the male from Dohrn. It may be recognised by its slender, graceful 

 form, shining brown colour and well developed wings, as well as by the 

 form of the forceps of the male and the abdominal tooth. 



OPISTHOCOSMIA N EOLOBOPHOROIDES, sp.n. 



Parva, glabra, fusca, nitida ; caput suturis nullis ; antennte fuscse, 12 

 segmentate. Pronotum capite angustius, quadratam ; elytris brevibus 

 apice truncatis ; alls nullis. Abdomen medio dilatatum, apice attenuatum 

 tuberculis lateralibus perspisiiis ; forceps $ bracchiis fcasi contiguis, paiillo 

 deplanatis, dehinc curvatis, primum extus, deinde intus orbem ovalera
