FAM. MEMBRACID.E 235 



median caiina strongly percurrent ; humeral angles large and blunt ; posterior process heavy , compressed 

 laterally, arising high above the scutellum, slightly angulate at the base, then highly curved over the 

 scutellum, then bent downward to touch the tegmina, tip suddenly acute and reaching just beyond the 

 internal angles of the tegmina; scutellum entirely exposed, triangular, about as broad as long, base 

 slightly swoUen, tip broadly notched. Tegmina long, slender and opaque ; base narrowly coriaceous 

 and punctate; veins heavy; iive apical and two discoidal cells ; tip pointed; apical limbus very broad. 

 Legs heavy; femora cylindrical; tibiae triquerate and roughly spined ; all tarsi about equal in length. 



Type phantasma Signoret. 



Geographical distpibution : This is definitely an African genus but one species has been 

 described from Ceylon.

Chapacters : We have not seen a representative of this genus but from Distanfs description 

 and figure it apparently bears a strong superficial resemblance to Anchon but differs particularly in the 

 venation of the hind wing which in Maarbarus shows four apical cells. We are reproducing Distant's 

 figure as our illustration of the genus and are summarizing his description to indicate tlie generic 

 characters as foUows : Head subquadrate, wider than high; base aicuate and strongly sinuate ; eyes 

 large and globular; ocelli large, prominent, nearer to each other than to the eyes and situated well above 

 a line drawn through centers of eyes; inferior margins of genas sloping and rounded; clypeus broad, 

 extending for two-thirds its length below inferior margins of genae, tip rounded. Pronotum convex, 

 bearing a pair of slender suprahumerals and a strongly angulate posterior process; metopidium 

 vertical, broader than high; median carina strongly percurrent; humeral angles large, triangular and 

 sharp; suprahumeral horns slender, much longer than the distance between their bases. extending 

 outward and upward with the tips curved backward; posterior process arising from near the base of 

 the pronotum but not touching scutellum, strongly angulate at the base and then extending obliquely 

 downward but not touching tegmina, tip acuminate and extending beyond the internal angles of the 

 tegmina; scutellum entirely exposed, subtriangular, longer than broad. Tegmina hyaline; basal and 

 costal areas broadly coriaceous and punctate; four apical and two discoidal cells; tip rounded; apical 

 limbus narrow. Legs simple and slender; hind tarsi longest. 



Type bubalus Kirby.
