FAM. MEMBRACID^ 221 



distance between their bases, tips more or less swollen, spinose and multicarinate; posterior process 

 heavy, sinuate, tectiform, nodulate above with the anterior node highest, roughly spinose, tip acute and 

 extending beyond the internal angles of the tegmina; scutellum narrowly exposed on each side. 

 Tegmina subhyaline; base narrowly coriaceous and punctate; veins heavy and spined; tip pointed; five 

 apical and two discoidal cells; apical limbus broad. Legs heavy, femora cyhndrical, tibias triquerous 

 or somewhat flattened ; hind tarsi longest. 



Type asper Jacobi. 



Geogpaphical distribution : This genus is known only from the African species which was 

 described from the type and which has since been reported by several authors.

214. GENUS SINENODUS GODING 



Sinenodus Goding, Journ. N. Y. Ent. Soc. XXXIX : 3ii (igSi). 



Ciiaracters : This is a monotypic genus, the type species of which we have not seen. 

 Moreover, no figure of the species has ever been pubhshed. However, Goding's good descriptions, 

 both of the genus and of the type species, make it easy to present a generic diagnosis as follows : Head 

 nearly square, roughly sculptured; ocelU conspicuous, farther from each other than from the eyes and 

 situated on a Une drawn through centers of eyes; inferior margins of genae broadly foUaceous. Pronotum 

 convex, rough, carinate and nodulate but not spinose; metopidium vertical; median carina strongly 

 percurrent; suprahumeral horns strong, heavy, quadrangular, extending upward, outward and sUghtly 

 incHned forward, tips broad and truncate; mesothorax with two teeth on each side; posterior process 

 long, slender, sUghtly sinuate, destitute of dorsal nodes, tip sharp and extending beyond the tips of the 

 tegmina; scutellum narrowly exposed on each side. Tegmina long, verj' narrow, semiopaque; veins 

 strong and colored; five apical and two discoidal ceUs; tip pointed; no apical Umbus. Legs strong; 

 femora cyUndrical; tibiae flattened and subfoliaceous. 



This genus is apparently closely related to the other two genera of the tribe but differs in not 

 being strongly spinose and in having the posterior process long, tricarinate and without dorsal nodes, 

 and in having vitreous tegmina and strongly dilated tibiae. 



Type gracilis Goding. 



Geographical distribution : The type species, which is the only species thus far described in 

 the genus, is from West AustraUa.
