ventro-cephalic angle rounding into the broadly convex ventral 

 margin, caudal margin strongly oblique, with humeral sinus 

 broadly concave. Tegmina and wings greatly reduced overlapping 

 in male, lateral in female. Ovipositor elongate and slender, straight 

 but showing greater obliquity of the dorsal than the ventral margin 

 toward the aciculate apex. Limbs short. Femora with genicular 

 lobes roundly produced, unarmed; internal margins alone armed 

 with small spines. Cephalic tibiae with auditory foramina rimate 

 and with a strong impression distad on each side beyond the 

 openings. Prosternum armed with two slender spines, mesoster- 

 num and metasternum very broad, the former with two lateral, 

 triangular spines. Cephalic coxae armed with a slender spine. 

 Caudal tibiae without dorso-distal spine or spur.

Wide dissimilarity is found when compared with other Australian 

 species of the Saginae. The head in some ways suggests the type 

 found in certain species of the otherwise very distinct genus 

 Salomona, belonging to the Agraeciinae. When compared, how- 

 ever, the head is seen to differ greatly in having its width and depth 

 nearly equal (due to the much shorter mouthparts), in the widely 

 separated eyes, much shorter antennae, shorter and bituberculate 

 fastigium of the vertex and almost vertical face.

In addition to the characters given in the generic description, 

 the following are noted. Size medium for this subfamily, which 

 includes very large species, form very thick-set. Occiput evenly 

 convex to the small, straight fastigium of the vertex, which is 

 directed cephalad and thus projects beyond the nearly vertical 

 plane of the broadly convex face, the surface of face rugulose, 

 particularly ventrad. Disk of pronotum smooth, velvety in ap- 

 pearance; lateral lobes weakly rugulose and shining in darkened 

 portions, the ventral and caudal margins cingulate, this decided 

 at the humeral sinus. Tegmina slightly broader than long, the 

 greater portion occupied by the large stridulating area, which is 

 broader than long. Wings pad-like, decidedly shorter than teg- 

 mina and with costal margins alone narrowly visible. Ultimate 

 abdominal tergite narrow, lateral margins slightly raised and convex 

 on each side of the depressed median point, where the small, acute, 

 shield-shaped supra-anal plate is attached and fused with this 

 tergite. Cercus triangular, nearly twice as long as basal width, 

 internal portion moderately lamellate with margin nearly straight 

 to apex, external margin very feebly convex to the minute and 

 sharply rounded apex, the latter ventral in position, curled inward 

 so that it is directed meso-distad; above which, at its base, is a
