296 INIr. ^V. I'. Distant 07i Homoptera. 



anterior femora with one or more distinct spines, posterior 

 tibia? with a few slender spines on apical areas ; metasternum 

 elevated and centrally sulcated ; tympana practically covered ; 

 opcrcula short, broad, their apices more or less convexly 

 rounded ; rostrum reaching the posterior coxae ; tegmiiia with 

 the basal cell broad, ulnar veins well separated at their bases. 

 Type, M. cli/peah's, Karscli {Platypleura). 



Sadaka, gen. nov. 



Head (including eyes) about as wide as base of mesonotum, 

 not truncate anteriorly, but frontally produced, about as long 

 as pronotum (excluding its posterior margin) ; pronotum 

 moderately transverse, its posterior margin half the lenirth of 

 vertex, the lateral margins medially angularly produced, 

 angular apices reaching base of basal cell of tegraina ; meso- 

 notum about as long as pronotum ; anterior femora with one 

 or more distinct spines on under surface ; posterior tibite with 

 a few slender spines on apical areas ; metasternum elevated 

 and centrally sulcate ; tympana covered; opercula short, 

 broad, their apices more or less convexly rounded ; rostrum 

 reaching the posterior coxse; tegmina with the basal cell 

 short and broad ; ulnar veins well separated at their bases. 



Type, S. virescens, Karsch (Plati/pleura). 

 - By the hyaline and non-opaque tegmina and wings this 

 genus resembles the subgen. Oxypleura [Platypleura], from 

 which it is at once separable by the frontally produced head. 



KOMA, gen. nov. 



Head (including eyes) wider than base of mesonotum, not 

 truncate anteriorly, but frontally produced, about as long as 

 pronotum (excluding its posterior margin) ; pronotum slightly 

 shorter than mesonotum, its posterior margin about half tiie 

 length of vertex, the lateral margins moderately dilated, 

 slightly angulated, but not reaching basal cell of tegmina ; 

 anterior femora witli one or more distinct spines on under 

 surface ; posterior tibiee with a few slender spines on apical 

 area ; metasternum elevated and centrally sulcate ; tympana 

 large; opercula short, broad, in type the margins oblique; 

 rostrum reaching the posterior coxse ; tegmina with the 

 basal cell short and broad ; ulnar veins well separated at their 

 bases. 



Type, K. homhifrons^ Karsch {Platypleura).
