Eemarks. I have several jears ago taken two specimens 

 in a warehouse at Kjobenhavn, perhaps imported from East- 

 India; also I have seen one specimen taken b}^ Dr. L. Reh 

 in the botanical garden at Haml)urg, where it is apparently 

 imported with plants from West-India. I have earlier de- 

 terminated it to be an Alloniscus and akin to All. cornutus
