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

 The colour of the thorax and elytra is a somewhat palo 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 costse, the interstices each with a single line 

 of punctures. 



The fomales differ from the males in having the antennse only 

 strongly dentate. 



The species known at present are all eastern.

Lycue (gen. 17) pnnctipennis, C. Waterh., Trans. Ent. Soc, 1878,

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

 scutelioque rufo-flavo ; elytria parallelis, rufo-flavis, sat fortiter 

 crebre striato-punctatis, interstitiis angustissimis, alternis parum 

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



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



The punctuation of the stria? 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 scutellum are 

 fuscous. 



Ditoneces rufescens. 



(Plate VII. fig. 8.) 



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

 scutello elytrisque rufo-flavis ; thorace longitudine haud latiori ; 

 elytris sat t'ortiter punetato-striatis, interstitiis angustissimis. 3 .

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. punctijjennis it is rather longer 

 than the joint.
