TAXONUS AGRORUM. 201 



The species are generally distributed over the Euro- 

 pean continent, but are rare outside of it, although 

 one species is found in Brazil. They appear in the 

 spring and early summer, and with the second brood 

 in Autumn. As for the larvse they are cylindrical, 

 usually green, paler at the sides. They feed on herba- 

 ceous plants (PolygOmim, Eumex) and pass the pupa 

 state in stems. Nine European species are known, 

 six from North America and one from Brazil.
