 'IVginina considerably shorter than pronotum, ahnost attingent, with apex 

 broadly rounded. 



Fincula represented by a pair of minute, slender processes, three times as 

 long as broad, which do not taper to their rounded apices (varying to more 

 slender and weakly tapering in the paratypes), are faintly divergent (varying 

 to moderately divergent in the paratypes), with length contained in that of 

 supra-anal plate nearly four times (varying to three and one-half times in the 

 paratypes). Supra-anal plate moderately elongate, shield-shaped; median 

 sulcus decided, with lateral margins distinctly carinate to slightly beyond 

 median point; transverse carina there, toward the lateral margins of this 

 sulcus, devclojied into a small but conspicuous lamella on each side, with margin 

 rounded; lateral portions of plate rather strongly concave, disto-lateral carinae 

 subobsolete. 



Cerci faintly bent slightly beyond end of ])roximal two-thirds, ajiproximately 

 twice as long as basal width, tai)ering strongly ijroximad; dorsal margin broad- 

 ly concave, ventral margin straight, becoming weakly convex distad; distal 

 portion very slender to the rather sharply rounded apex, the external surface 

 showing faint subapical concavity. Subgenital plate with median section of 

 (Hiual dejjth laterad and mesacl, curving and tapering meso-distad to the blunt
