wrinkled, this decided toward the lateral carinse. Lateral lobes 

 of pronotum with greatest depth equal to dorsal length; 

 cephalic margin weakly convex and scarcely oblique to the ob- 

 tuse-angulate, sharply rounded ventro-cephalic angle, ventral 

 margin broadly convex to the rather broadly rounded, rect- 

 angulate, ventro-caudal angle; caudal margin broadly concave; 

 sulci deeply impressed on lateral lobes. 



Tegmina represented by broadly lanceolate pads with 

 rounded apices, which are attingent (or weakly overlap), nearly 

 as long as combined length of head and pronotum. Veins and 

 cross-veinlets of tegmina heavy and distinct, forming a coarse 

 and irregular network, in which, however, the principal veins, 

 and particularly the humeral vein, are clearly defined. 



Short ovipositor valves with heavy apices sharply curved. 

 Caudal femora heavy, the ventral and particularly the dorsal 

 portions evenly and broadly lamellate, the lamellation of the 

 dorsal margin being over half as wide as the external pagina. 



General coloration (type, intensive) dark chestnut brown. 

 Head paling to hazel on occiput, cheeks tawny, this continued 

 as a U-shaped band from eyes, its lower portion crossing the 

 labrum, frontal costa and ventral portion of infra-ocular sulcus 

 suffused with black. Antenn?e hazel, deepening to chestnut 

 brown distad. Pronotum with median carina russet, bordered 

 by a band of mars brown, lateral carinae buffy tinged with rus- 

 set, this broadening into a band on the metazona, the triangular 

 areas between these and the medio-longitudinal band velvety 

 blackish brown. Lateral lobes of pronotum irregularly paling 

 to tawny meso-proximad and with a buffy callosity mesad 

 which extends as a narrow line ventro-cauded to the caudal 

 margin above the ventro-caudal angle. Tegmina pecan brown, 

 the veins of the dorsal field suffused with black. Ventral sur- 

 face of abdomen argus brown. Cephalic and median limbs 

 hazel, mottled with chestnut brown. Caudal femora light 

 ochraceous-tawny in proximal two-fifths, this terminated in 

 external face of dorsal surface by a large triangular patch of
