6 HOMOPTERA 



moderately transverse, its posterior margin half the length of vertex, the lateral margins medially 

 angularlv produced, angular apices reaching base nt basal cell of tegmina; mesonotum about as long 

 as pronotum ; anterior femora with one or more distinct spines on under surface; posterior tibia- 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 coxa . 

 tegmina with the basal cell short and broad; ulnar veins well separated at their bases. 



By the hyaline and non-opaque tegmina and wings this genus resembles the subgen. Oxypleuta 

 (Platypleura . from wich it is at once separable by the frontally produced head.

Koma. Distant, Ann. Mag. Nat. Hist. (7), Vol. 14, p. 296 (1904). 



Characters. — 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 the length of vertex, the lateral margins 

 moderately dilated, slightly angulated, but not reaching basal cell of tegmina ; anterior femora with one 

 or more distinct spines on under surface; posterior tibiae with a few slender spines on apical areas; 

 metasternum elevated and centrally sulcate; tympana large; opercula short, broad, in type the margins 

 oblique; rostrum reaching the posterior coxae; tegmina with the basal cell short and broad: ulnar veins 

 well separated at their bases.
