211. genus hybandoides distant 



Hybandoides Distant, Ann. Mag. Nat. Hist. XVI : 327 (igiS). 

 Platyceras Schmidt, Soc. Ent. XLI : 6. 22 (1926). 



Characters : A small but very distinct genus characterized by the simple, poirect anterior 

 pronotal horn and bituberculate base of the head. Head subquadrate, wider than high ; base arcuate, 

 sinuate and bituberculate ; eyes globular and protruding; ocelli small but conspicuous, farther from 

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

 margins of genjE sinuate and sloping downward; clypeus large, trilobed, extending for two-thirds its 

 length below inferior margins of genae, tip broad and truncate. Pronotum extended forward and 

 upward into a simple, porrect horn; metopidium vertical, twice as broad as high; median carina faintly 

 percurrent; humeral angles heavy, triangular and blunt ; anterior pronotal horn heavy, somewhat 

 flattened laterally, sharply carinate above and below, extending forward over the head, length variable; 

 posterior process slender, straight, impinging on tegmina, tip sharp and just reaching the internal 

 angles of the tegmina ; scutellum narrowly exposed on each side. Tegmina long, narrow, semiopaque; 

 basal and costal areas broadly coriaceous, punctate and pubescent; veins distinct but venation very 

 irregularly arranged particularly in the apical region ; usually five apical cells but an indefinite number 

 of discoidal cells; tip sharply pointed; no apical Hmbus. Legs simple; femora cylindrical; tibiffi 

 triquerate; hind tarsi longest.

212. Genus CENTROCHARES STAL 



Centpochares Stal, Analect. Hem. 386 (1866). 



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

 New World genus Pterygia. They are rough and spinose with broad spreading suprahumerals and more 

 or less foliaceous head and legs. The scutellum, however, is fully developed and entirely exposed 

 and the sides of the of the mesonota are armed with teeth. Head subtriangular, very roughly
