200 HOMOPTERA 



wider than high; base arcuate and weakly sinuate; eyes globular; ocelli small, inconspicuous, twice as 

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

 margins of genae rounded; clypeus extending for two-thirds its length below inferior margins of genas. 

 Pronotum convex with horizontal suprahumerals; metopidium sloping, broader than high; median 

 carina faintly percurrent; humeral angles triangular and blunt; suprahumeral horns projecting almost 

 directly outward, variable in size and structure, the tips being sharp, truncate or dentate; posterior 

 process long, strong, nearly cylindrical, tricarinate, very strongly sinuate, arising from above the 

 scutellum, tip sharp and extending beyond the end of the abdomen, almost to the tips of the tegmina; 

 scutellum entirely exposed, subtriangular, tip broadly notched. Tegmina hyaline; base broadly 

 coriaceous and punctate; venation irregular; five apical cells with curved veins; one or two discoidal 

 cells; apical limbus narrow. Legs simple; hind tarsi longest. 



The variation in the structure of the suprahumerals and in the wing venation of this genus as well 

 as the erratic geographical distribution of the forms may warrant a further subdivision of the genus if 

 and when more species are described which will indicate definite distinctions between these variations. 



Type serpentinus Funkhouser. 



Geographical distpibution : This genus. as at present constituted, shows species both in 

 Africa and in the East Indies. We are inclined to believe that the two groups may eventually prove to 

 represent different genera.

191. Genus AMITROCHATES DISTANT 



Amitrochates Distant, Rhynch. Notes 327 (1916). 



Characters : Small, rough insects characterized by the very nodose and sinuate posterior 

 process and the short, bulbous, spined suprahumerals. Head subquadrate, declivous, longitudinally 

 ridged, twice as broad as high; base arcuate and sinuate; eyes large and globular; ocelH inconspicuous, 

 about equidistant from each other and from the eyes and situated above a line drawn through centers 

 ofeyes; inferior margins of genae rounded; clypeus extending for more than half its length below the 

 inferior margins of the genae, tip truncate. Pronotum convex with bulbous suprahumerals which 

 terminate in a spine; median carina percurrent; humeral angles heavy and blunt; suprahumeral horns 

 thick and subconical, projecting directly outward and ending in a sharp spine; posterior process heavy, 

 very sinuate, nodose, rough, elevated above the scutellum and ending in a spine which reaches beyond 

 the internal angles of the tegmina; scutellum entirely exposed, subtriangular, longer than broad, tip 

 upcurved. Tegmina hyaline; base broadly coriaceous and punctate; five apical and two discoidal cells; 

 apical limbus broad. Legs simple; hind tarsi longest.
