ThivS, although a most distinct and remarkable genus, may be 

 considered a modification of Sijnelasma, wanting the prothoracic 

 tooth, and having the first three joints of its antennae plumosely 

 fringed. The species described by M. Thomson, C. antennalus, 

 is from Java. From the clause " antennarum art. 2 — 3 et 5 — 11 

 nigris, artic. .3° flavo, apice nigro," and from no mention being 

 made of the fringe clothing the upper part of the third joint, I 

 have come to the conclusion that the example described below is 

 a distinct although nearly alh'ed species, the more so that I have 

 recently seen another species from Pulo Penang, to which the 

 same remarks may be applied.
