FAM. MEMBRACIDiE 189 



177. Genus CALLICENTRUS Stal 



Callicentrus Stal, Bid. Memb. Kan. 290 (1869). 

 Pyramba Buckton, Mon. Memb. 248 (igoS). 



Characters : Medium-sized to large insects with well-developed suprahumerals which vary 

 greatly in size and structure and with a simple straight posterior process which entirely coiiceals the scu- 

 tellum. Head subquadrate, twice as wide as high, transversely ridged across the middle and much de- 

 flexed below the ridge; base weakly arcuate ; eyes very large andglobular; ocelU large, prominent, 

 protruding, farther from each other than from the eyes and situated well above a line drawn 

 through centers of eyes; inferior margins of gense strongly sinuate; clypeus extending for half its length 

 below inferior margins of genae, tip sharply pointed. Pronotum convex with strong suprahumeral horns; 

 metopidium sloping, a little wider than high; median carina faintly percurrent ; humeral angles large, 

 triangular, blunt; suprahumeral horns long, strong and sharp but varying in size and structure, usually 

 much longer than the distance between their bases and extending upward and outward ; posterior process 

 simple, straight, tectiform, impinging on tegmina, tip sharp and reaching beyond the internal angles of 

 the tegmina, usually as far or farther than the end of the abdomen ; scutellum entirely concealed. 

 Tegmina long, narrow, hyaline; base narrowly coriaceous and punctate; tip pointed; five apical and 

 two discoidal cells; apical hmbus narrow. Legs simple; all tarsi about the same in length. 



Type ignipes Walker. 



Geographical distrlbution : A West Indian genus which, curiously enough, seems to be 

 limited to Jamaica. The species are apparently quite abundant on that island but none have ever been 

 reported from any other region.

178. genus daimon buckton 



Daimon Buckton, Mon. Memb. 241 (igoS). 



Characters ; The insects of this genus bear a strong superficial resemblance to those of the 

 genus Pterygia of the subfamily Membracinae but the legs are not at all foliaceous and the scutellum is 

 well-developed and exposed. Head subquadrate, wider than high, somewhat deflexed; base nearly 

 straight; eyes globular; ocelli large, equidistant from each other and from the eyes and situated on a Hne 

 drawn through centers of eyes; mferior margins of genas rounded; clypeus extending for half its length 

 below inferior margins of genae. Pronotum convex with strong ampliate supiahumerals; metopidium 

 nearly vertical, a little wider than high; median carina percurrent; humeral angles large and blunt ; 

 suprahumeral horns long, strong, with tips broadly flattened; posterior process long, heavy, with a dorsal
