The single specimen (in the Museum collection) of this 

 distinct and magnificent species is in a rather damaged con- 

 dition. There are but ten complete joints to the antenna;, 

 and these together surpass the body by about a third part. 

 The fine silky golden -yellow pubescence gives rather feeble 

 moire reflexions on the elytra. Owing to the shortness and 

 great thickness of the third and fourth joints of the antennas 

 I was at first inclined to place the species in Pachydissus ; 

 but the size and remaining characters seem to fit it better for 

 Neoceramhyx. As in the true PachydissuSj we see that even 

 amongst evidently nearly related species of the same genus 

 the third joint may vary considerably in length and thickness. 

 Jt must be admitted that Neoceramlnjx — taking N. paris, 

 Wied., as the type — cannot by any hard-and-fast characters 

 be differentiated from Pachydissus. The eyes offer no dis- 

 tinguishing character, and the anterior cotyloid cavities may 

 in some species of Puckydissus, and even in some specimens 

 of the same species, e. g. P. picipennis, be angulate externally, 

 while in others they are completely closed. It was unfortu- 

 nate that Lacordaire should have taken the characters of the 

 eyes and of the anterior coxal cavities as the basis of his sub- 

 division of this group.
