220 HOMOPTERA 



sculptured ; base arcuate and feebly sinuate; eyes globular ; ocelli large, prominent, twice as far from 

 each other as from the eyes and situated above a line drawn through centers of eyes; inferior margins 

 of genae subfoliaceous, extending downward in lobes on each side of the clypeus and giving a trilobed 

 appearence to the face; clypeus broad, extending for three-fourths its length below the inferior margins 

 of the genae, tip rounded or truncate. Pronotum convex, very rough and spinose; metopidium vertical, 

 broader than high, and bearing short, irregular spines; median carina percurrent and spinose; humeral 

 angles heavy, triangular and spinose or dentate; suprahumeral horns well developed, projecting 

 outward and upward, longer than the distance between their bases, irregularly covered with short 

 spines, tips usually more or less foliaceous and carinate; posterior process heavy, sinuate, rough, 

 spinose, slightly elevated above scutelium, bearing rough, irregular nodes on its dorsal surface, the 

 subapical elevation largest and ridged, tip blunt and extending almost to the tips of the tegmina; 

 scutellum almost entirely exposed, subtriangular, longer than broad, tip broadly notched. Tegmina 

 long, narrow and opaque ; basal and costal areas narrowly coriaceous and punctate; veins distinct and 

 nodulate; five apical and two discoidal cells; tip pointed; apical hmbus broad. Legs heavy, tibiae 

 distinctly foliaceous ; all tarsi about equal in length. 



Type korrificus Westwood. 



Geographical distribution : Centrochares is definitely a genus of Oceanica with more species 



found in the Philippines than in any other region.

213. Genus NEGUS Jacobi 



Negus Jacobi, Kil. Exp. XH : 121 (igio). 



Chapacters : The type species of Negus shows characters which would seem to warrant its 

 being placed in a distinct genus. The structure of the pronotal process is quite different from that of the 

 other two genera of the tribe and the scutellum is only narrowly exposed on each side. The characters 

 which would appear to be generic are as follows. Head subquadrate, broader than high ; base arcuate ; 

 eyes globular; ocelli large, prominent, farther from each other than from the eyes and situated about on 

 a line drawn though centers of eyes; inferior margins of genas extended into pointed lobes which give a 

 trilobed appearance to the apical outline of the face; clypeus broad, extending for half its length below 

 inferior margins of genas, tip rounded. Pronotum convex, very rough and spinose; metopidium 

 vertical, higher than broad, rough and spinose; humeral angles large and triangular; median carina 

 percurrent; suprahumeral horns strong, spinose, extending upward and outward, longer than the
