 the comparison to X. americanus. 



KU. According to Loew, Monogr. etc. I, 16 the bristle-like fourth 

 antennal joint ascribed by Mr. Walker to this species renders it 

 very doubtful, whether it is properly referred to the Xylophagidae. 

 I do not remember having seen it in the Biit. Mus,

' Observation. Mr. Loew (Sillim. Journ. N. Ser. XXXVII, 317)

 76, 5, from the West Indies , Wiedemann (Auss. Zw. I, 86) says, 

 that it is in no way different „from errans and hence, the same 

 as Coen. ferruginea Meig.".
