HOMOPTERA 



width at the base; median carina faintly percuirent; humeral angles broad and blunt; anterior pronotal 

 horn erect, heavy, conical or cyhndrical, usually branched at the top into two lateral branches or nodes 

 which are very variable in size and shape but are always dilated, bulbous or swollen and generally extend 

 outward and backward; posterior process slender, triquerate, sinuate, impinging on tegmina, tip sharp 

 and reaching beyond the end of the abdomen and almost to the tips of the tegmina; scutellum very 

 narrowly exposed on each side. Tegmina hyahne; basal and costal areas coriaceous and punctate; veins 

 heavy; five apical and two discoidal cells; tip rounded; apical limbus well developed. Legs simple; 

 hind tarsi longest.

218. genus ELAPHICEPS BUCKTON 



Elaphiceps Buckton, Mon. Memb. 217 (1903). 



Chapacteps : This is one of the most remarkable and bizarre of all of the membracid genera 

 because of the extreme specialization shown in the multibranched anterior pronotal process, Head 

 subquadrate, about twice as broad as high, roughly sculptured; base highly arcuate, strongly sinuate 

 and feebly bituberculate; eyes large, ovate and protruding; ocelli large, prominent, a little farther from 

 each other than from the eyes and situated about on a line drawn through centers of eyes; inferior 

 margins of genee sinuate and extending slightly forward; clypeus very large, ovate, extendlng for more 

 than half its length below inferior margins of genae, tip rounded. Pronotum extended upward into a 

 conical anterior horn which is branched and rebranched; metopidium convex, sloping, about as high 

 as the breadth of the base; median carina faintly percurrent ; humeral angles broad, heavy, triangular 

 and blunt; anterior pronotal horn erect, conical or cylindrical, branched at the top into two strong 

 lateral branches each of which is rebranched, the tips of branches very sharp; posterior process long, 

 slender, tricarinate, arising from near the top of the anterior horn just behind or below the lateral 

 branches and extending backward and downward high above the scutellum, the tip acuminate and 

 reaching beyond the internal angles of the tegmina; scutellum entirely exposed, heavy, subtriangular, 

 longer than broad, base swollen, tip truncate. Tegmina long, narrow, semiopaque; basal and costal 

 areas broadly coriaceous and punctate and usually pubescent; veins heavy; five apical and tvvo discoidal 

 cells; tips rounded; apical limbus broad. Legs long, slender and simple; hind tarsi longest. 



Type cervus Buckton.
