PALEX. 69' 



tubercle at each angle. Forceps : in the (S with branches remote at 

 the base, trigonal at the base itself, quite straight in the basal half, 

 tapering, then abruptly bent inwards at a right angle, the points 

 overlapping, the apical half thus forming a line parallel to the 

 posterior margin of the last dorsal segment and at right angles with 

 the main axis of the insect ; about half way down the straight 

 part there is, on the inner margin, a short tooth : in the 5 the 

 branches are elopgate, very gently sinuate, almost straight, 

 incurved at the apex, with a sharp depressed tooth on the inner 

 margin in the basal third, and strongly creuulated as far a» 

 this tooth.

Type in the Genoa Museum. 



Although originally described by de Bormans, from Pulo- 

 Penang and from Sumatra, the pair in the author's possession 

 were from Pea's collection and came to him through de Bormans ; 

 yet the latter never quoted this species from Burma. The only 

 specimens from Karen-ni, May to December, quoted by de Bormans 

 are referred by him to Platijlahia major, and perhaps, owing to 

 the inconspicuous pygidium, he regarded them as identical with 

 that species in 1894, but separated them in his later work in 

 1900. 



The form of the forceps is quite characteristic and they are not 

 likely to be confused with anything else. 



This species is totally distinct from any other known Labidurine 

 earwig ; but it has so strong a resemblance to the genera Platij- 

 labia and Sparatta, that the structure of the pygidium must be 

 carefully examined. 



Subfamily II. ECHIN0S0MATIN.51:. 



Pronotum transverse, decidedly broader than long, elytra 

 complete, with no lateral keels, entirely concealing the scutellum. 

 Pemora not compressed or keeled. Abdomen short, broad, rather 

 dilated, body clothed with short stiff bristles ; forceps short, 

 cylindrical, remote at base in male, arcuate and unarmed. 



This subfamily includes only the old genus EcJiinosoma, which 

 has close affinities with the Labidurhuc. 



The short, thick-set body, densely clad with stiff hairs and 

 many obtuse thick bristles, gives these earwigs a very distinctive 

 appearance.
