Tricentus convergens is the type species of the genus, origin- 

 ally described from the Philippines by Walker and apparently 

 not uncommon. It may be at once recognized by the very high 

 and flattened, almost foliaceous, suprahumeral horns. 



Ferruginous, finely punctate, sparingly pubescent, with some- 

 times a white tomentose area above and behind the eyes. Supra- 

 humeral horns more than twice as long as the distance between 

 their bases, projecting strongly forward and upward, sub- 

 parallel, farther apart at their apices than at their bases, tips 

 much rounded and flattened, not at all sharp; posterior process 

 almost straight, tricarinate, dorsal carina high and sharp, ex- 

 tremity reaching just beyond internal angle of tegmina. Teg- 

 mina subhyaline, base brown and punctate. Undersurface of 

 body dark brown. Legs ferruginous. 



Length, from head to extremity of tegmen, 6 mm. ; length of 

 pronotal horns, 2 to 3 mm. ; width between extremities of horns, 

 2 to 3 mm.

Tricentrus fairmairei is one of the abundant species of the 

 genus as represented in the Islands. It may be recognized super- 

 ficially by the reddish tinge over the entire body and tegmina.
