canaliculate ; elytris novemcostatis, costis alternatis elevatis, inter- 

 stitiis uniseriatim puuctatis. 5 . Long. 3 lin. 



Hah. Penang {J. C. Bowring, Esq.). 



The remark appended to the foregoing species applies also to this. 

 The colour of the thorax and elytra is a somewhat pale rusty red ; 

 the extreme apex of the elytra is a little dusky. 



DITONECES. 



Rostrum none. Antennae of the male with a slender pubescent 

 branch emitted from the third to tenth joints. Thorax even above, 

 with a very short longitudinal impression behind. Elytra pubescent, 

 with nine nearly equal costae, the interstices each with a single line 

 of punctures. 



The females differ from the males in having the antennae only 

 strongly dentate. 



The species known at present are all eastern. 



Ditoneces punctipennis.

Lvcus (gen. 17) punctipennis, C. Waterh., Trans. Ent. Soc, 1878, 

 "pp. 100 and 108. 



Nigro-piceus, supra subtiliter pubescens ; fronte fiava ; thorace 

 scuteUoque rufo-flavo ; elytris parallelis, rufo-flavis, sat fortiter 

 crebre striato-punctatis, interstitiis angustissimis, alternis parum 

 magis elevatis ; ore coxisque testaceis. J , $ . Long. 3| lin. 



Rab. Java (J. C. Bowring, Esq.). 



The punctuation of the striae of the elytra is rather strong ; the 

 alternate interstices are very slightly more elevated at the base than 

 the others. 



The female has the antennae shorter than those of the male and 

 strongly dentate ; the middle of the thorax and the scuteUum are 

 fuscous. 



Ditoneces rufescens. 



(Plate VII. fig. 8.) 



ParaUelus, depressus, pubescens, nigro-piceus ; capite, thorace, 

 scutello elytrisque rufo-flavis ; thorace longitudine baud latiori ; 

 elytris sat fortiter punctato-striatis, interstitiis angustissimis. c? . 



Long. 4 lin. 



Hab. Java (J. C. Bovrrmg, Esq.). 



This species differs from the preceding in having the thorax 

 rather longer and in having the branches emitted from the antennal 

 joints shorter, the branch of the sixth joint being about half the 

 length of the joint, whereas in D. punctipennis it is rather longer 

 than the joint.
