Two males differ from seven females from British Caffraria, and 

 agree with a very large (63 mm. long) male from Delagoa Bay, in the 

 Indian Museum, in the absence of lobes in the posterior legs, the sole 

 character upon which P. spurca is founded by Stai, who was acquainted 

 only with the male sex, of which lobeless hindlegs would appear to be 

 a very usual, if not an invariable, peculiarity. 



Bates had already united these two supposed species. 



Hab.— Cape of Good Hope (Gharpentier, Serville) ; Natal (Stal, 

 Bates); South Africa (Saussure) ; Bedford, British Caffraria; Delagoa 

 Bay; Madagascar (Bates). ° 



Genus 3. Heteeochsta, Westwood. 



c?^ S . Body greatly elongated, bacilliform, without foliaceous lobes 

 and spines. 



Head between the points of the sharp conical corneal spines nearly 

 twice as wide as the pronotum at its dilatation ; vertex concave, its 

 median and sub-median lobes lower than its extensive lateral iJbes 

 which with the eyes are bent forwards at obtuse angles to the rest of 

 the vertex. 



Organs of flight coloured: tegmina with the marginal field ir- 

 regularly reticulate, the anterior radial forked just before the apical 

 fourth, the posterior radial simple, the anterior prong of anterior ulnar 

 simple, the posterior 4-branched, the dividens anastomosed with the 

 posterior ulnar just before the posterior margin, and the plicate vein reach- 

 ing the margin, but sending its three or four branches through the aual 

 gusset, which is hence venose : wings with the anterior area narrow 

 and the anterior ulnar simple and unbranched.
