TEICENTBUS.

narrow aud obliquely directed upward, triangularly subacute ; 

 the posterior process very broad and robust, strongly centrally 

 cariuate, the lateral carinatious more prominent on apical area, 

 its extreme apex obtusely acute and reaching the posterior angle 

 o£ the inner margin ; tegmina coarsely punctate on the black basal 



area ; legs normal. 



Length 7; breadth lat. pronot. process. 4i nnlhm. 



Hah. Sookna, o'3'i feet. 



This species is to be structurally recognized by the robust 

 pronotal posterior process and the non-carinate transverse 

 processes. 



B. Head and pronotum testaceous or ocliraceom.

 p. 247, t. Ix, f. <;(]'»0--!)- 



Head and pronotum dark ochraeeous, pilose; extreme apices of 

 transverse pronotal processes and about apical third of posterior 

 process black; body beneath fuscous, palely pilose; legs ochraeeous, 

 bases of femora narrowly fuscous ; tegmina pale ochraeeous, sub- 

 hyaline ; pronotum palely pilose : the latei-al transverse in-ocesses as 

 seen from above moderately broad, anteriorly a litth? amphate and 

 rounded, apices subacute, broadly carinate near middle ; posterior 

 process robust, tricarinate, sides oblique, apex about reaching the 

 posterior angle of inner margin. 



Length 5 ; breadth lat. pronot. process, oh milllm. 



Hah. Tenasserim : Myitta (Doheyti/). 



A small species, to be recognized by its pilose character, the 

 black apical area to the posterior pronotal process, and by its 

 general pale coloration. 



21S6. Tricentrus assamensis, sp. n. 



Head, pronotum and legs pale testaceous ; apices of lateral and 

 posterior pronotal processes black ; body beneath piceous, palely 

 pilose; tegmina subhyaline, talc-like, venation brownish-ochraceous, 

 base narrowly l)ro\vnish-ochraceous, opaque; pronotum thickly 

 punctate, lateral pronotal processes as seen from above somewhat 

 short and narrow, strong, medially carinate, apices subacute and 

 slightly recurved, as viewed in front narrower, more obliquely up- 

 wa"rdly directed and the ai)ices more acute; posterior process some- 

 what short, somewhat raised, centrally and laterally cariuate, the 

 central carination finely continued through i)ronotum, the apex not 

 quite reaching the posterior angle of the inner margin of the 

 tegmina; tegmina with the veins a little granulose, the basal 

 opaque area punctate. 



Jjength G ; breadth lat. pronot. process. 3.4 millim. 



Hah. Assam ; Margherita. 



Allied to the preceding species, T. selenus. Bnckt., but with the 

 lateral pronotal processes very much more slender and their apices 

 more broadlv black.
