This species is the largest Tryponceus yet discovered ; it is 

 very near thoracicus, but is in every way more robust. The 

 spine or prolongation of the pygidium, viewed sideways, ap- 

 pears slightly raised, not depressed as in thoracicus ; the 

 apex of the rostrum is broader, and the tibiae are armed with 

 stronger and more robust teeth. All the plates of the sub- 

 structure are also much broader. 



I have two examples, both females, taken by Mr. Belt. 



Tryponceus bombacis, n. sp. 



Cylindricus, niger, nitidus ; fronte excavata punctata, inter oculos 

 tenuissime strigoso, rostro apice bituberculato ; pronoto dense et 

 grosse punctate-, lateribus marginato ; elytris parce punctatis ; pro— 

 pygidio pvgidioque dense punctatis, prosterno parallelo marginato. 

 L. '2i mill.

I took two examples of this species, one at Peradeniya on 

 a Ft'cus, the other at Kitulgal on a Bombax ; both are, I be- 

 lieve, females. This and the following, like the two Japanese 

 species, fall into Tryponceus rather than Trypeticus. All four 

 have certain characters in common, and probably represent a 

 section of the genus peculiar to Eastern Asia. 



Tryponceus veda, n. sp. 



Cylindricus, niger, nitidus ; antennis pedibusque rufo-piceis, pronoto 

 stria laterali integra parum dense punctato ; elytris sat parce 

 punctatis ; propygidio pygidioque dense punctatis. L. 3^ mill. 



c? . Fronte leviter impressa lateribus basique margine elevatis, 

 rostro apice obtuso reflexo, pronoto antice retuso, opaco ; pygidio 

 obtnso. 



5 . Fronte fortiter impressa, apice subbituberculato. 



Hob. Dikoya, Ceylon. 



The presternum is quadrate in front, sinuate at the base, and 

 punctured, with a broad, rather deep and wide sulcus on each 

 side, reaching from the base to three fourths of its length. 

 The mesosternum is obtuse, arcuate at the sides, and the 

 broader part has a similar sulcus to the presternum. 



I saw plenty of this species in a stump of iron-wood, with 

 a Platypus, which has the apices of the elytra bifurcate, but 

 only succeeded in securing two, which are fortunately one of 

 each sex. 



Teretrius cestivzis, n. sp. 



Cylindricus, subelongatus, niger, nitidus, undique sat dense punctu- 

 latus ; fronte convexa, stria laterali supra oculos, pronoto stria 

 marginali integra, interstitio lato ; prosterno basi proftmde inciso,
