Characters. — Head horizontal, as long as space between eyes, not anteriorly deflect* .i. hunt 

 very prominent, margins of front and vertex obliquely subcontinuous; pronotum as long as mesonotum, 

 its lateral margins oblique, sinuate, obscurely dentate; abdomen considerably longer than space between 

 apex of head and base of cruciform elevation; tympana imperfectly covered, the flaps shorter and nar- 

 rower than the tympanal cavities; rostrum about reaching the posterior coxae; anterior femora armed 

 beneath with two or three strong spines; opercula extending to more than half the length of the abdo- 

 men, sinuate, wide apart and on the lateral abdominal areas; tegmina broad, their greatest breadth 

 more than one third of their length, apical areas eight, basal cell much longer than broad.

Characters. — - Head moderately deflected in front of eyes, its length about equal to space 

 between eyes, its lateral margins discontinuous, the lateral margins of vertex being more or less at right 

 angles to those of front, its width between eyes being distinctly narrower than base of mesonotum ; face 

 globose; pronotum a little shorter than mesonotum. its lateral margins somewhat angulately sinuate, 

 broad and laminate on posterior half; abdomen broad, robust, and moderately inflated, above somewhat 

 laterally oblique on each side, beneath strongly channelled near each lateral margin ; tympanal coverings 

 about as broad but shorter than the tympanal cavities, their length variable, either very short as in 

 K. panlherina or about half the length of cavities as in K. javanensis; opercula in male short, transversi , 

 not extending beyond base of abdomen; rostrum considerably passing the posterior coxa?; anterior 

 femora strongly spined beneath ; tegmina and wings hyaline, the first maculate, variable in length, about 

 as long as body, as in K. panthaina, or longer than body, as in K . javanensis, basal cell longer than broad ; 

 apical areas eight.
