Characters : This genus is closely related to the preceding but the insects are usually smaller 

 and the head is not trilobed. It is particularly characterized by the normal venation and by the tiuncate 

 tegmina. Head subquadrate, about as wide as high; base high and bituberculate; eyes somewhat 

 flattened laterally; ocelli large, conspicuous, much farther from each other than from the eyes and 

 situated above a line drawn through centers of eyes; inferior margins of genae sinuate; clypeus extending 

 for more than half its length below inferior margins of genas. Pronotum elevated into a high, anterior, 

 bifurcate pronotal horn which is usually curved backward; metopidium vertical, higher than broad; 

 median carina percurrent; humeral angles weak and rounded ; mesonotum lobate or toothed at sides; 

 posterior process heavy, tectiform, with a rounded elevation before the apex, tip sharp and just reaching 

 the internal angles of the tegmina on which it impinges for its entire length; scutellum well exposed on 

 each side. Tegmina long, semiopaque, coriaceous and punctate on basal two-thirds; veins indistinct 

 except in apical region; apex obliquely truncate; five apical and two discoidal cells; apical limbus well 

 developed especially in anal region. Legs slender, simple; hind tarsi longest. 



Type sarasinorum Breddin. 



Geographicai distribution : This genus seems to be limited to the East Indian Islands.
