i*. Vertex but little longer than broad, acutely pointed 

 anteriorly. 

 y. Front very long and narrow, but without ang^Jlate 

 ridge above; ocelli near apex of vertex; tegmina 



truncate apically Varta Dist. 



y. Front not long and narrow, but with an angulate 

 ridge above ; ocelli not near apex of vertex ; tegmina 



rounded apically Sabima Dist. 



V. Vertex little less than twice as long as broad, or longer. 

 j^. Vertex with anteocular portion far longer than inter- 

 ocular. 

 A;\ Anteocular portion of vertex with lateral margins 

 in line with outer margins of eyes, 

 r. Pronotum and vertex medially longitudinally 

 carinate; margins of anteocular portion of 

 vertex sinuate; clypeus narrowed to tip. 



Sussana Dist. 

 r. Pronotum and vertex noncarinate; margins of 

 anteocular portion of vertex straight; clypeus 

 broadened at tip and marginate. 



Muirella Kirk. 



k'. Anteocular portion of vertex greatly contracted 



within outer eye margins; clypeus narrowed 



to tip Bharmma Dist. 



f. Vertex with anteocular portion far shorter than 

 interocular. 

 Iv. Front with sides strongly sinuate and distinctly 

 broadened above; lateral carinate margins of 

 vertex parallel as far as to base of vertex, ante- 

 riorly curved on to the temples next the eye; 

 front more or less distinctly medially carinate; 

 scutellum longer than vertex.... Tharra Kirk. 

 k'. Front with sides straight, scarcely broadened 

 above; lateral carinate margins of vertex sud- 

 denly converging posteriorly and "terminating 

 in a sulcate process;" front noncarinate; scutel- 

 lum about as long as vertex Soortana Dist. 



h'. Vertex but little and very obtusely produced in front of 

 eyes, commonly about as long as broad, never much 

 longer than broad between eyes, sometimes much less, 

 t'. Head distinctly narrower than pronotum. 



j^. Head about half the width of pronotum and not as 



wide as scutellum; vertex about as long as width 



between eyes, subangulate anteriorly and smooth, 



noncarinate; ocelli very near eyes.... Placidus Dist. 



;"'. Head always wider than half pronotum and wider 



than scutellum; vertex very obtuse and usually 



carinate medially or laterally or both; ocelli very 



near eyes. 



/c'. Face broader than long; vertex broader than long 



and far shorter than pronotum; tegmina with 4 



apical cells Kunasia Dist.
