Hagen.] 278 [March 17, 



There are five species known from Europe, six from North Am- 

 erica including one from Cuba, two from Africa, four from Ceylon, 

 two from the Pacific ; of course this is probably only a small part 

 of the actually existing species. The American species are M. 

 montanus, M. angulatus, M. variolosus, M. insipidus, M. Cubanus, 

 M. angustus (probably M. subanticus Walk.) all easily recognized. 

 Only one, M. angulatus, is also found in Europe, and M. montanus 

 much resembles European species. None of the American species 

 seems to be common except the widely-spread M. insipidus.
