i52 HOMOPTERA 



much nearer to each other than to the eyes and situated about on a line drawn through centers of eyes; 

 inferior margins of genas sinuate; clypeus extending for about one-fourth its length below inferior 

 margins of genas. Pronotum with a long, strong, subcylindrical, bkint anterior horn which extends 

 forvvard and upward, arising from in front of the humeral angles; metopidium vertical, triangular; 

 median carina percurrent; humeral angles broad, blunt, triangular, extending directly laterad as far 

 beyond the eyes as the width of the eyes; sides of pronotum punctate, weakly ridged posteriorly, 

 extended dovvnward to cover about one-third of the tegmina; posterior process heavy, tectiform, acute, 

 just reaching the tips of the tegmina. Tegmina about two-thirds exposed ; hyahne, translucent or 

 clouded; basal costal areas coarsely punctate; five apical and two discoidal cells ; apical limbus broad. 

 Legs simple, subquadrate in cross-section ; hind tarsi longest. 



This genus has had a rather peculiar history in that at various times seventy-eight different 

 species have been assigned to it, all but three of which have now been removed to other genera. 



Type bimaculata Fabricius. 



Geographical distribution : A distinctly tree-inhabiting genus with tvvo species widely 

 distributed over almost all parts of the United States and Canada and a third questionable species 

 from Brazil.

127. Genus GLOSSONOTUS BUTLER 



Glossonotus Butler, Cist. Ent. II : 222 (1878). 



Characters ; Closely related to the preceding genus but distinguished from it by the fact that 

 the pronotal horn is practically erect and laterally compressed. It piobably has, in fact, closer phylo- 

 genetic relationship to Telamoiia than to Thelia but the position of the dorsal crest, placed well forward 

 on the pronotum, causes it to fall naturally in a taxonomic key in the position to which we have 

 assigned it. Head subquadrate, roughly sculptured; base arcuate and very strongly sinuate; eyes 

 large and ovate; ocelli large, very prominent, twice as far from the eyes as from each other and 

 situated about on a hne drawn through centers of eyes; inferior margins of genae sinuate; clypeus 

 not extending below the inferior margins of the genae but continuing the irregular sinuate apical 

 outline of the face made by the genje. Pronotum elevated in a single, laterally flattened, anterior 

 horn which is erect or leans only slightly forward and is placed well forward on the dorsum; meto- 

 pidium sloping, subtriangular; median carina strongly percurrent; humeral angles broad, blunt, 

 triangular, extending laterad as far beyond the eyes as the width of the eyes ; sides of pronotum 

 punctate, weakly, longitudinally multicarinate posteriorly, extending downward to cover about one- 

 fourth of the tegmina. Tegmina hyaline; three-fourths exposed; basal area coarsely punctate ; five 

 apical and two discoidal cells; apical limbus broad. Hind wings with median apical cell sessile and 

 truncate at base. Legs simple, angulate in cross-section; hind tarsi very little longer than the others. 



Type acumiiiatus Fabricius. 



Geographical distribution ; A strictl}' North American genus but with species represented 

 in practically all parts of the United States and Canada.
