HOMOPTERA 



small, slightly elevated, equidistant from each other and from the eyes; eyes slanting, twice as wide as 

 high. Pronotum smooth, polished, lightly punctate, not pubescent; humeral angles rounded, very 

 shghtly produced; no suprahumeral horns or other anterior processes ; dorsum convex, rounded, highest 

 in middle with weak median carina ; sides weakly impressed; scutellum entirely concealed by pronotum; 

 posterior process wide, high, rounded, suddenly narrowed at tip which just reaches internal angles of 

 tegmina. Tegmina entirely free, the inner margin impinging on pronotum, hyahne or translucent; 

 five apical cells and one discoidal cell, the apical veins distinctly curved and the median apical cell 

 irregularly truncate; apical limbus very broad. Legs and tarsi simple.

44. GENUS SMILIORHACHIS FAIRMAIRE 



Smiliorhachis Fairmaire, Rev. Memb. 291 (1846). 



Characters : Small. slender-bodied, inconspicuously coloied insects with a straight posterior 

 process and the apical cells of the tegmina strongly curved. Head triangular, roughly sculptured, with 

 the base weakly arcuate; clypeus projecting for half its length below the inferior margins of the genas 

 and continuing the line made by these margins; ocelli small, inconspicuous, equidistant from each 

 other and from the eyes and situated about on a line drawn through centers of eyes. Pronotum 

 slightly elevated, somewhat compressed laterally, with a strong, sharp median carina; humeral angles 

 rounded and weakly protluced; 110 suprahumerals or other anterior processes; scutellum entirely hidden 

 by sides of pronotum ; posterior process narrow, tectiform, sharply ridged, with the acute tip extend- 

 ing to a point just beyond the internai angles of the tegmina. Tegmina entirely free, broad, usually 

 hyaline with some maculations, veins strong. five apical cells and one discoidal cell, the veins of the 

 apical cells being very strongly curved; apical limbus broad. Legs simple; all tarsi of equal length. 



Type variegata Fairmaire.
