42. GENUS IRIA Stal 



iria Stal, Bid. Hem. Syst. Sog (1867). 



Characters : Small, slender, inconspicuous insects of dull colors, with low rounded anterior 

 pronotum, short, thin posterior process and entirely exposed tegmina. The head is swollen, projects 

 forward and is subquadrate, about twice as broad as long; the clypeus is bulbous, projecting forward 

 farther than the frons and extending for two-thirds its length below the inferior margins of the genae; the 

 ocelli are very large, conspicuous, prominent, twice as far from each other as from the eyes and situated 

 well above a line drawn through centers of eyes. The pronotum is low, convex, tricarinate, rounded, 

 with weak obtuse humeral angles and no suprahumerals or other anterior projections; the median carina 

 is strongly percurrent; the scutellum is entirely hidden by the sides of the pronotum ; the posterior 

 process is short, slender and spine-Iike, almost flat but with a strong central ridge and a carina on 

 each side, and does not extend as far backward as the anterior angles of the tegmina, being only about 

 half as long as the abdomen. The tegmina are entirely free and almost entirely hyaline, the base 

 narrowly coriaceous and opaque ; there are five apical cells and one discoidal cell and the apical veins 

 are slightly curved; there is no transverse vein across the middle of the corium and the apical limbus is 

 very narrow. The legs are simple an 1 the tarsi uniform in size.
