little higher than long, Avith the lower margin rotundato- prominent 

 in the middle; hind angle obtuse, rounded; fore margin sinuate. 

 Prosternal tubercle low, conical or narrowed towards the obtuse 

 apex. Mesosternal interspace trapezoidal, in the male almost as 

 broad as long, in the female distinctly transverse. Elytra more 

 or less abbreviated ; wings coloured, with the fore margin dark. 

 Hind femora strongly dUated and distinctly incrassate, especially 

 in the male; upper carina strongly serrate; lower margin of the 

 externomedian area straight, or nearly so ; lower outer area convex, 

 widest beyond the middle; lower carina straight from the base 

 up to the middle or even beyond it, then convex ; inner lower area 

 dilated. Hind tibiae more or less bent. 



(^. The last tergite dilated and incrassate, with a large rotundato- 

 trapezoidal emargination. Supra-anal plate trapezoidal with the 

 hind angles obtuse; a narrow apical lobe; a row of four tubercles 

 about the middle ; median carina low, sulcate, narrowly bifurcate 

 basally. Cerci hook-shaped with the apical (ascending) jiart longer 

 than the basal part, laterally compressed and dilated at the apex. 

 Subgenital plate small, very obtusely conical. 



$. Subgenital plate shallowly, but distinctly impressed along its 

 middle; hind margin very obtusely produced, with two obtuse 

 lateral emarginations. Lower valves of the ovipositor with broadly 

 rounded basal teeth ; apical parts narrow and small. 



Genotype : Amhhjphymus miniatus, sp. n. 



In the structure of genitalia, both male and female, 

 as well as in the shape of the hind legs, this genus is closely 

 related to Rhachitopis, but differs from it in the far less 

 rugose head and pronotum, better developed temporal 

 foveolac, broader and less impressed fastigium of the 

 vertex, abbreviated elytra, coloured wings, dilated at the 

 apex male cerci and longitudinally sulcate female subgenital 

 plate. 



I know two species of this genus, both described below, 

 and it is possible that Euryphynms xanthocnemis Brancs. 

 also belongs here, but its description is practically worth- 

 less, being too short and based on the female sex only.

cJ. Not large, but rather heavily built. The sides of the frontal 

 ridge perfectly straight. Head almost smooth, but not at all shining. 

 Pronotum not coarsely, but distinctly rugulose; disc distinctly
