Pajstesthia Saltsstjeii, n. sp. 



$ P. mandarinea, Saussure, Melanges Orthopt., p. 100, PL 3, Fig. 23, non p. 40, 

 PI. 1, Fig. 25. 



I bave recently received from Jobore in tbe Malay Peninsula a fine 

 series of specimens of P. mandarinea, none of wbicb exbibit tbe least 

 approach to tbe remarkable structure of tbe abdomen seen in the insect 

 described and figured by De Saussure as tbe supposed female of it. Tbe 

 larvae of P. mandarinea, moreover, are jet-black tbrougbout, while those of 

 P. Sausswrii are deep black-brown symmetrically variegated with pale test- 

 aceous on every part of the body, including the legs, which are ringed, the 

 antennse, which are tipped, and the head, which is triply banded, with the 

 same colour. A further reason for refusing to accept the insect figured by 

 De Saussure on PL 3 {pp. supra cit.) as the female of the one represented on 

 PL I is, that the latter is itself also a female, the sides of the pronotum in 

 the true males of which are produced into huge curved horns each separated 

 from the broad semioval median lobe covering the head by a deep rounded 

 emargination. 



Hab. — A single specimen of the male from Sikkim (L. Mandelli). 

 This insect having been captured just prior to the last moult, the organs 

 of flight are still in rudiment, and the pronotum is still non-ernarginate.
