Bialysis. 



<Iissiiiiilis Walker, Dirt. Saund , 4; List, etc I, 128 (X. Americnnus 

 Wied. ?). - - Locality not given, but probably North America, from 

 the comparison to X. americanus. 



NB. 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. 



Macroccromys.

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

 states that this species is the same as the european C. ferruyinea. 

 About Sicus crucis Fabr. Ent Syst. IV, 264, 7, and Syst. Antl. 

 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 Com. ferruginea Meig.".
