^ . $ . Vertex directed forwards and slightly upwards, strongly 

 protuberant between the juxtocular lobes ; the protuberance flat and 

 triangular in front, behind convex and trefoil-shaped, being divided 

 into three lobes, one large and median and two small, equal, and lateral ; 

 the former produced at the apex into a long, narrow, and very gradually 

 tapering horn, which is expanded, together with the lobes themselves, 

 in the middle line posteriorly and at the sides, into sharp foliaceous 

 crests, and which may be rudimentary in the male ; facial shield pen- 

 tao-onal, about as long as broad, marked with two blunt longitudinal 

 ridges, and with its basal angle slightly projecting. Eyes oval, tolerably 

 prominent, not narrowed as in Phyllocrania. Pronotum long and 

 slender, nearly five times as long as its parallel- sided anterior lobe, 

 very gradually widening from its narrowest part just behind the 

 dilatation, and equally gradually increasing in height, to its base, close 

 to which it bears a prominent smooth tubercle, and where it is nearly as 

 wide as at the distinct dilatation ; prosternum slightly and decreasingly 

 roof-shaped from the insertion of the forelegs backwards. Anterior coxae, 

 long and slender, when laid back not reaching to the base of prothorax, 

 their apical lobes not divergent, but close together ; tibiae half the 

 leno-th of the femora, with only the basal 5 or 6 of the spines of the outer 

 edo-e curved towards the margin ; femora with 3 spines on the outer 

 edo-e and 4 on the disc ; four posterior legs short ; femora with geni- 

 cular spines and with foliaceous lobes on the lower crest ; tibiso with 

 their apical half inflated latero- superiorly. Axillary and anal veins 

 of tegmina running one immediately after the other into the internal 

 ulnar vein, first ulnar vein branched ; ulnar vein of wings 2-branched. 

 Abdomen depressed, widening more (?) or less ( S ) from base to end of 

 5th somite, the remaining somites forming a triangular figure with more 

 or less serrated sides; the dorsal arc of its 10th somite roof-shaped, 

 broader than long, subtriangular. 



This interesting and curious form may be provisionally placed be- 

 tween the African genus Vhyllocrania and the Oriental genus Anaxarcha.
