i38 HOMOPTERA 



gular, smooth; base highest next to eyes and lowest in the middle as in the preceding genus; eyes large, 

 ovate and protruding ; oceUi small, equidistant from each other and from the eyes and situated about 

 on a hne drawn through centers of eyes ; inferior margins of geuEe weakly sinuate ; clypeus projecting for 

 about one-third its length below inferior margins of genae and continuing the hne of these margins to 

 complete the triangular apical outhne of the face. Pronotum broadly convex, usually somewhat 

 constricted at about the middle and highest behind this constriction ; metopidium sloping, broader than 

 high; median carina obsolete ; no suprahumerals; humeral angles well developed, triangular, blunt; 

 sides of pronotum punctate but not ridged; posterior half of pronotum heav}', rounded, somewhat 

 swollen, blunt, the apex not quite reaching the tips of the tegmina. Tegmina not more than half 

 exposed ; usually hyaUne with very heavy veins; cells irregular in shape ; iive apical and three discoidal 

 cells; median apical cell transverse, base nearly straight and petiolate; first apical cell situated well 

 forward on the costal margin as in the preceding genus; apical limbus broad. Legs simple, subcylin- 

 drical; hind tarsi longest. 



Type reticulata Fabricius. 



Geographical distribution : A Middle-American genus found chiefly in Central .America and 

 Mexico and in the northern part of South America.

Characters : A distinct genus of small, inconspicuous, robust bodied insects characterized by 

 the low. convex pronotum without processes, partly exposed tegmina, and particularly by the median 

 apical cell of the corium which is definitely transverse and has a perfectly straight base from the middle 

 of which a vein extends directly cephalad. Head convex, rounded, subtriangular ; base weakly arcuate 

 and sinuate ; eyes ovate; ocelli prominent, equidistant from each other and from the eyes and situated on 

 a line drawn through centers of eyes ; inferior margins of genas sinuate ; clypeus feebly trilobed, extend- 

 ing for about half its length below inferior margins of genae. Pronotum low, convex, usually slightly 

 depressed in middle; metopidium convex, wider thanhigh; median carinapercurrent; no suprahumerals; 

 humeral angles well developed, bioad, triangular, blunt; sides of pronotum punctate but not ridged; 

 lateral margins curved downward to cover about one-third of the tegmina; posterior process heavy, 

 convex, blunt, extending just beyond the internal angles of tegmina. Tegmina about two-thirds expos- 

 ed; usually hyahne; venation regular; five apical and three discoidal cells; median apical cell trans- 

 verse, base straight and petiolate; apical limbus moderate. Legs simple ; hind tarsi longest.
