neio species of Clerida. 403 



pore toto siibtus, prothoracis lateribus, antennis pedibusque 

 nigris, pronoto basi medio tuberculato, elytris unicostatis, 

 sutura parum elevata. 

 Long. 4|^ lin. 



Though allied to the preceding in colour, this species 

 can hardly be confounded with it, even if much larger 

 specimens than the type should be foimd, if the very much 

 finer and sparser pubescence and single conspicuous costa 

 of the elyti-a are noticed. The head is shining, spotless, 

 mouth, palpi and antennfB black, thorax shining, sides 

 widely black, "with a shallow depression each side of the 

 centre of the disk, and a shining tubercle in the middle of 

 the base ; elytra even, parallel, a single raised costa from 

 the base to near apex, the second and thu'd costas barely 

 visible.

Tenerus cruentatus, n. sp. 



Brevior, sanguineo-rufus, immaculatus, nitidus, pronoto 

 basi tuberculato, elytris unicostatis sutura vix elevata. 



Long. 3 lin. 



Allied to T. siamensis, but distinct by the coloration; 

 the thorax is visibly punctured under a very strong lens, 

 the elytra impunctate, the costa distinct, but terminating 

 before the apex.

Tenerus ceramensis, n. sp. 



Nigro-fliscus, capite feiTugineo, nigro-notato thorace 

 ferrugineo, disco et margine antico nigris elytris flavo- 

 feiTugineis limbo externo apiceque indeterminate fiiscis 

 tricostatis. 



Long. 5 lin. 



Head with the epistoma and crown black, finely punc- 

 tured, semiopaque ; thorax black in front and down part 

 of the sides, disk black ; elytra plainly three-costate, the 

 first conspicuous at the base, the third commencing in the 

 humeral callus, not very distinct but all traceable to near 

 the apex ; the margin, except at the base, and about one- 

 third of the elytra at the apex, fuscous.
