FAM. MEMBRACID^ 2i3 



highly arcuate and weakly sinuate; eyes globular; ocelli large, conspicuous, equidistant from each 

 other and from the eyes and situated on a line drawn through centers of eyes; inferior margins of genae 

 sloping and sinuate; clypeus deflexed. extending for more than half its length below inferior margins 

 of genae. Pronotum convex, subconical, with erect contiguous or united suprahumerals; metopidium 

 conical, higher than wide ; median carina percurrent ; humeral angles triangular and blunt ; suprahumeral 

 horns erect, usuall}' grown together at their bases, tips contiguous and blunt; posterior process long, 

 slender, straight or only shghtly sinuate, impinging on tegmina, tip acute and reaching beyond the 

 internal angles of the tegmina; scutellum broadly exposed, triangular, tip bifurcate. Tegmina hyaline; 

 base broadly coriaceous and punctate; veins strong ; five apical and two discoidal cells ; apical Hmbus 

 well developed. Legs simple; hind trochanters unarmed; hind tarsi longest.

204. GENUS CRITO DISTANT 



Crito Distant, Rhynch. Notes 43 (1916). 



Characters : If we have correctly identified the small, inconspicuous insect which we beh'eve 

 is Distant's type of this genus, it is close to the representatives of Ebhul on the one hand, and to 

 Acanthucus on the other, but belongs to a different tribe from either, and seems to have distinct generic 

 characters as follows : Head subquadrate, a little broader than high; base highly arcuate and weakly 

 sinuate; eyes ovate ; ocelli small, inconspicuous, farther from each otherthan from the eyes and situated 

 well above a line drawn through centers of eyes; inferior margins of genae weakly sinuate ; clypeus 

 trilobed, the median lobe much the largest, extending for more than haif its length below inferior 

 margins of genae, tip rounded; pronotum convex, with small suprahumerals; metopidium almost vertical, 

 about as high as broad; median carina faintly percurrent; humeral angles strong, triangular and blunt ; 

 suprahumeral horns small, triangular and sharp; posterior process heavy, very strongly sinuate or 

 waved, tip acute and extending well beyond the internal angles of the tegmina but not reaching the 

 apex of either tegmina or abdomen ; scutellum narrowly exposed on each side. Tegmina subhyaline 

 and mottled; basal and costal areas narrowly coriaceous and punctate; veins strong; five apical and 

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



Type festivus Distant. 



Geographical distributlon : This genus is known only from the type species from Queensland.
