MEGALOUACNK. 

 (Type, Ips. fasciata, E.) 



I have reiiained the genus Dacne of Lacordaire, retaining 

 that name in the sense it was originally given. The pre- 

 sent genus is very homogeneous. 



Sexual characters are here visible, the anterior or pos- 

 terior tibiie being curved, and sometimes crenulated; in 

 M. hcros the last ventral segment is sharply carinate ; in 

 all the prosternum is deeply punctured.
