XlPHIDION LONGICEPS, 11. sp. 



$ . Pale greenish with a pink median baud running from the 

 vertex to the base of the pronotum ; wings green, antennae, legs, and 

 cerci pink ; abdomen maculated with pink and green. The head and 

 pronotum are longer than in the other South African species known to 

 me, and are also more parallel ; the tegmina reach the median part 

 of the fourth abdominal segment, the cerci are robust, and nearly 

 as long as the two abdominal joints preceding, horizontal, gradually 

 tapering from the middle to a sharp point, and plainly grooved longi- 

 tudinally for the same distance, the right outwardly, the left inwardly ; 

 the spines are robust, horizontal, and at right angles to the lobe, 

 crossing each other at rest. The three basal joints of the antennae 

 are somewhat thick. 



Length of body (cerci excl.) 23-25 mm. ; of pronotum 4f mm. ; 

 of cerci 2J-3 mm. ; of hind femur and hind tibia 14 and 12 mm. 

 respectively.

XlPHIDION RHODESIANUM, U. Sp. 



$ . Light testaceous with a tinge of green ; a median pinkish- 

 brown band runs from the vertex to the base of the pronotum, and 

 there is another much narrower baud running laterally from behind 

 the eye to the edge of the prouotum, the two bands being separated 

 by a broad yellowish interval ; abdomen with a broad dorsal slightly 

 inf uscate band and a lateral one also divided by a lighter interval ; 

 tegmina fiavesceut, cerci darker ; head shorter thau the pronotum, 

 fastigium- projecting, narrow, parallel, truncate, rounded at tip ; pro- 

 notum one-fourth louger than broad ; tegmina reaching only the base 

 of the fifth abdominal segment ; the cerci are horizontal, long, sub- 

 cylindrical, but tapering to a sharp point where they are slightly 

 impressed lengthways, each is provided with a strong, sharp inner 

 tooth, of identical length and slightly curved at tip. Anterior tibiae 

 with five spines underneath. 



The livery is uot unlike that of X. longiceps, but this species is 

 easily recognised by the reduced length of the head ; the cerci are 

 a little shorter, less deeply impressed longitudinally, and the inner 

 spines are slightly more hooked. 



Length of body 15-15| mm.; of pronotum 3 mm.; of cerci 1 mm.; 

 of hind femur aud hind tibiae 12J mm. and 11^ mm. respectively.
