265. Genus PROMINTOR Distant 



Promlntor Distant, Rhynch. Notes LVII : 495 (igiS). 



Characters : This genus is very close to the preceding and differs chiefly in having five apical 

 celis in tlre corium and in having the posterior process curving upwards and' backward behind the 

 scutellum. The insects are small and inconspicuous. Head subquadrate, wider than long, shghtly 

 deflexed; base arcuate and sinuate; eyes ovate; ocelli large, farther from each other than from the eyes 

 and situated above a line drawn through centers of eyes; inferior margins of gena.' sloping and sinuate; 

 clypeus extending for half its length below inferior margins of gense. Pronotum elevated, convex, 

 unarmed; metopidium sloping, wider than high, an irregular foveate spot on each side; median carina 

 strongly percurrent; humeral angles very weak and poorly developed; no suprahumeral horns; posterior 

 process heavy, sinuate, curving downvvard to apex of scutellum and then upward, tip sharp and just 

 about reaching the internal angles of the tegmina; scutellum large, heavy, entirely exposed. Tegmina 

 hyaline, base coriaceous and punctate; five apical and three discoidal cells; apical limbus well developed. 

 Legs simple; hind tarsi longest. 



Type nominatus Distant. 



Geographical distribution : This genus is known only from ihe tj'pe sjiecies which was 

 collected at the mouth of tlie Umkomaas River in Natal.

266. Genus HAMMA BUCKTON 



Hamma Buckton, Trans. Linn. Soc. Zool. IX : 33o (igoS). 



Gharacters : This genus bears a strong supeificial resemblance to the genus Amitrochates Distant, 

 having a similar sinuate and nodulate posterior process but the pronotum is unarmed which of course 

 places it in a different tribe and the teginen shows a distinct and rather peculiar stigma on the costal 

 margin, the latter character being characteristic of the genus and very rare in the MembracidcC. The 

 members of the genus are all small, dark insects and are apparently very rare. Head subtriangular ; base 

 arcuate and slightly sinuate; eyes small and ovate; ocelli small, inconspicuous, equidistant from each 

 other and from the eyes and situated above a Une drawn through centers of eyes ; inferior margins of 

 gena^ sloping and weakl}' curved; clypeus subquadrate, extending for half its length beyond internal 

 angles of tegmina. Pronotum convex, gibbous, unarmed, tuberculate and spined; metopidium nearly 

 vertical, about as broad as high; median carina irregularly percurrent; humeral angles strong and 

 sharp; no suprahumeral horns; posterior process heavy, sinuate, roughly trilobed, tubeiculate, spined, 

 arising well above the scutelluin and touching tlie tegmina only at tlie middle lobe, tip rounded or
