162. GENUS CENTRUCHOIDES FOWLER 



Centpuchoides Fowler, B. C. A. II : 161 (1896). 



Characters : Large heavy-bodied insects with strong suprahumeral horns, a long robust 

 posterior process and with long, semiopaque or translucent tegmina showing five apical and three 

 (sometimes four) discoidal cells. Head subquadrate, about twice as broad as high, very roughly 

 sculptured; base weakly arcuate, strongly sinuate and sHghtly tuberculate ; eyes ovate, nearly twice as 

 broad as high; ocelH prominent, elevated, equidistant from each other and from the eyes and situated 

 on a line drawn through centers of eyes; inferior margins of geniE irregularly sinuate; clypeus roughly, 

 longitudinally ridged, extending for two-thirds its length below inferior margins of genae. Pronotum 

 convex and bearing a pair of strong, well-developed suprahumeral horns which are variable in length 

 and in structure ; metopidium nearly vertical, broader than high ; median carina percurrent; humeral 

 angles heavy, triangular, blunt; posterior process long, tectiform, reaching to the internal angles of the 

 tegmina, impinging on the scutellum and on the tegmina; scutellum narrowl}* exposed on each side. 

 Tegmina long, semiopaque or translucent; basal and costal areas coriaceous and punctate ; five 

 apical cells; three or four discoidal cells; tip pointed; no apical limbus. Legs simple; tibia^ not 

 flattened ; all tarsi about equal in length. 



Type laticornis Fowler. 



Geographical distribution : This genus is known only from Mexico and Central America and 

 is represented by the foUowing two species : 



1. laticoynis Fowler, B. C. A. II : 162. i (1896). Panama, Honduras. 



2. oppugnans Walker, List Hom. B. M. SuppL 160 (i858). — PL 9, Mexico, Yucatan.

163. Genus BOCYDIUM Latreille 



Bocydium Latreille, Reg. Anim. II : 219 (1829). 

 Sphaeronotus Laporte, Ann. Ent. Soc. Fr. I : 229 (i832). 



Characters : One of the most remarkable of all of the genera of the Membracidje and with 

 structures as curious and bizarre as those of any insect of any family. The members of this genus are 

 characterized particularly by the fact that the pronotum bears slender spines on which are located inflated 

 and decorated globules of various numbers and sizes. Surely from the signs which are displayed above 

 their heads, these must be the pawn-brokers among insects. These insects are usually small in size and 

 deHcate in structure. Head subtriangular, trilobed; base feebly sinuate, lowest in the center ; eyes 

 large and globular; ocelli large, prominent, elevated, three times as far from each other as from the 

 eyes and situated close to the upper margin of the head, far above a line drawn through centers of eyes ; 

 inferior margins of genae flattened and extended slightly forward ; clypeus extended for half its length 

 below the inferior marginsof the genas to form the central lobe of the trilobed inferior outline of the 

 face. Pronotum convex and bearing a slender upright branched spine decorated with a number of
